In their most common sense, the terms thought and thinking refer to cognitive processes that can happen independently of sensory stimulation . Their most paradigmatic forms are judging , reasoning , concept formation, problem solving , and deliberation . But other mental processes, like considering an idea , memory , or imagination , are also often included. These processes can happen internally independent of the sensory organs , unlike perception. But when understood in the widest sense, any mental event may be understood as a form of thinking, including perception and unconscious mental processes. In a slightly different sense, the term thought refers not to the mental processes themselves but to mental states or systems of ideas brought about by these processes.
247-502: The mind is that which thinks , feels , perceives , imagines , remembers , and wills . The totality of mental phenomena, it includes both conscious processes, through which an individual is aware of external and internal circumstances, and unconscious processes, which can influence an individual without intention or awareness. Traditionally, minds were often conceived as separate entities that can exist on their own but are more commonly understood as capacities of material brains in
494-423: A Jiva is either samsari (mundane, caught in cycle of rebirths) or mukta (liberated). According to this belief until the time the soul is liberated from the saṃsāra (cycle of repeated birth and death), it gets attached to one of these bodies based on the karma (actions) of the individual soul. Irrespective of which state the soul is in, it has got the same attributes and qualities. The difference between
741-404: A midlife crisis involving an inner conflict about personal identity , often associated with anxiety, a sense of lack of accomplishments in life, and an awareness of mortality. Intellectual faculties tend to decline in later adulthood, specifically the ability to learn complex unfamiliar tasks and later also the ability to remember, while people tend to become more inward-looking and cautious. It
988-473: A nerve net , like jellyfish , and organisms with bilaterally symmetric bodies , whose nervous systems tend to be more centralized. About 540 million years ago, vertebrates evolved within the group of bilaterally organized organisms. All vertebrates, like birds and mammals , have a central nervous system including a complex brain with specialized functions while invertebrates, like clams and insects , either have no brains or tend to have simple brains. With
1235-546: A resurrection . The oldest existing branches of Christianity, the Catholic Church and the Eastern and Oriental Orthodox churches, adhere to this view, as well as many Protestant denominations. Some Protestant Christians understand the soul as life, and believe that the dead have no conscious existence until after the resurrection (this is known as Christian conditionalism ). Some Protestant Christians believe that
1482-446: A bicycle or playing a musical instrument. Another distinction is between short-term memory , which holds information for brief periods, usually with the purpose of completing specific cognitive tasks, and long-term memory , which can store information indefinitely. Thinking involves the processing of information and the manipulation of concepts and ideas . It is a goal-oriented activity that often happens in response to experiences as
1729-460: A bodily change causes mental discomfort or when a limb moves because of an intention . According to substance dualism , minds or souls exist as distinct substances that have mental states while material things are another type of substance. This view implies that, at least in principle, minds can exist without bodies. Property dualism is another view, saying that mind and matter are not distinct individuals but different properties that apply to
1976-418: A body and a soul. Paul said that the "body wars against" the soul, "For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit" (Heb 4:12 NASB), and that "I buffet my body", to keep it under control. According to Thomas Aquinas , the soul is tota in toto corpore . This means that the soul is entirely contained in every single part of
2223-473: A calculator extend the mind's capacity to store and process information. The closely related view of enactivism holds that mental processes involve an interaction between organism and environment. The mind–body problem is the difficulty of providing a general explanation of the relationship between mind and body, for example, of the link between thoughts and brain processes. Despite their different characteristics, mind and body interact with each other, like when
2470-604: A changeless intelligible world. Instead, they only exist to the extent that they are instantiated. The mind learns to discriminate universals through abstraction from experience. This explanation avoids various of the objections raised against Platonism. Conceptualism is closely related to Aristotelianism. It states that thinking consists in mentally evoking concepts. Some of these concepts may be innate, but most have to be learned through abstraction from sense experience before they can be used in thought. It has been argued against these views that they have problems in accounting for
2717-483: A changeless realm different from the sensible world. Examples include the forms of goodness, beauty, unity, and sameness. On this view, the difficulty of thinking consists in being unable to grasp the Platonic forms and to distinguish them as the original from the mere imitations found in the sensory world. This means, for example, distinguishing beauty itself from derivative images of beauty. One problem for this view

On the level of syntax, the representational system has to possess two types of representations: atomic and compound representations. Atomic representations are basic whereas compound representations are constituted either by other compound representations or by atomic representations. On
3211-462: A complex neural network and cognitive processes emerge from their electrical and chemical interactions. The human brain is divided into regions that are associated with different functions. The main regions are the hindbrain , midbrain , and forebrain . The hindbrain and the midbrain are responsible for many biological functions associated with basic survival while higher mental functions, ranging from thoughts to motivation, are primarily localized in
3458-413: A complex physical environment through processes like behavioral flexibility, learning, and tool use. Other suggested mechanisms include the effects of a changed diet with energy-rich food and general benefits from an increased speed and efficiency of information processing. Besides the development of mind in general in the course of history, there is also the development of individual human minds . Some of
3705-405: A content that can be expressed by a declarative sentence . When a person believes that it is raining, they have the propositional attitude of belief towards the content "it is raining". Different types of propositional states are characterized by different attitudes towards their content. For instance, it is also possible to hope, fear, desire, or doubt that it is raining. A mental state or process
3952-446: A creative process of internally generating mental images. Unlike perception, it does not directly depend on the stimulation of sensory organs. Similar to dreaming , these images are often derived from previous experiences but can include novel combinations and elements. Imagination happens during daydreaming and plays a key role in art and literature but can also be used to come up with novel solutions to real-world problems. Motivation
4199-400: A different form of malfunctioning. Anxiety disorders involve intense and persistent fear that is disproportionate to the actual threat and significantly impairs everyday life, like social phobias , which involve irrational fear of certain social situations. Anxiety disorders also include obsessive–compulsive disorder , for which the anxiety manifests in the form of intrusive thoughts that
4446-466: A distinct phenomenology but contends that thinking still depends on sensory experience because it cannot occur on its own. On this view, sensory contents constitute the foundation from which thinking may arise. An often-cited thought experiment in favor of the existence of a distinctive cognitive phenomenology involves two persons listening to a radio broadcast in French, one who understands French and
4693-482: A great variety of methods to study the mind. Experimental approaches set up a controlled situation, either in the laboratory or the field, in which they modify independent variables and measure their effects on dependent variables . This approach makes it possible to identify causal relations between the variables. For example, to determine whether people with similar interests (independent variable) are more likely to become friends (dependent variables), participants of
4940-409: A heavenly gem whose reality the most learned of men hath failed to grasp, and whose mystery no mind, however acute, can ever hope to unravel". Bahá'u'lláh stated that the soul not only continues to live after the physical death of the human body but is in fact immortal. Heaven can be seen partly as the soul's state of nearness to God, and hell as a state of remoteness from God. Each state follows as
5187-516: A life force. The concept of jiva in Jainism is similar to ātman in Hinduism; however, some Hindu traditions differentiate between the two concepts, with jiva considered as individual self, while atman as that which is universal unchanging self that is present in all living beings and everything else as the metaphysical Brahman . The latter is sometimes referred to as jiva-ātman (a soul in

#17327805869825434-534: A living body). The Quran , the holy book of Islam , uses two words to refer to the soul: rūḥ (translated as spirit, consciousness, pneuma, or soul) and nafs (translated as self, ego, psyche, or soul), cognates of the Hebrew ruach and nefesh . The two terms are frequently used interchangeably, although rūḥ is more often used to denote the divine spirit or "the breath of life", while nafs designates one's disposition or characteristics. In Islamic philosophy,
5681-669: A long evolutionary history starting with the development of the nervous system and the brain . While it is generally accepted today that mind is not exclusive to humans and various non-human animals have some form of mind, there is no consensus at which point exactly the mind emerged. The evolution of mind is usually explained in terms of natural selection : genetic variations responsible for new or improved mental capacities, like better perception or social dispositions, have an increased chance of being passed on to future generations if they are beneficial to survival and reproduction . Minimal forms of information processing are already found in
5928-436: A low number of atomic representations. This applies to thought since human beings are capable of entertaining an infinite number of distinct thoughts even though their mental capacities are quite limited. Other characteristic features of thinking include systematicity and inferential coherence . Fodor argues that the language of thought hypothesis is true as it explains how thought can have these features and because there
6175-432: A more abstract level that cannot be achieved by physics. According to functionalism , mental concepts do not describe the internal constitution of physical substances but functional roles within a system. One consequence of this view is that mind does not depend on brains but can also be realized by other systems that implement the corresponding functional roles, possibly also computers. The hard problem of consciousness
6422-421: A more explicit explanation of what computation is. A further problem consists in explaining the sense in which thinking is a form of computing. The traditionally dominant view defines computation in terms of Turing machines , though contemporary accounts often focus on neural networks for their analogies. A Turing machine is capable of executing any algorithm based on a few very basic principles, such as reading
6669-488: A natural consequence of individual efforts, or the lack thereof, to develop spiritually. Bahá'u'lláh taught that individuals have no existence prior to their life here on earth and the soul's evolution is always towards God and away from the material world. The traditional doctrine in Buddhism regarding the soul, self, or ego is that it is non-existent as a separate, permanent entity. The non-existence of self ( anatman ),
6916-463: A new problem. On this view, the important difference is that this process happens inwardly as a form of simulation. This process is often much more efficient since once the solution is found in thought, only the behavior corresponding to the found solution has to be outwardly carried out and not all the others. When thinking is understood in a wide sense, it includes both episodic memory and imagination . In episodic memory, events one experienced in
7163-577: A person actively remembers the fact that the Eiffel Tower is in Paris then this state is mental because it is part of consciousness; when the person does not think about it, this belief is still a mental state because the person could bring it to consciousness by thinking about it. This view denies the existence of a "deep unconsciousness", that is, unconscious mental states that cannot in principle become conscious. Another theory says that intentionality
7410-401: A problem, developing a plan to address it, implementing the plan, and assessing whether it worked. Thinking in the form of decision-making involves considering possible courses of action to assess which one is the most beneficial. As a symbolic process, thinking is deeply intertwined with language and some theorists hold that all thought happens through the medium of language . Imagination is
7657-413: A reaction to particular external stimuli . Computationalism is the most recent of these theories. It sees thinking in analogy to how computers work in terms of the storage, transmission, and processing of information. Various types of thinking are discussed in academic literature. A judgment is a mental operation in which a proposition is evoked and then either affirmed or denied. Reasoning , on

7904-484: A reaction to particular external stimuli. On this view, having a particular thought is the same as having a disposition to behave in a certain way. This view is often motivated by empirical considerations: it is very difficult to study thinking as a private mental process but it is much easier to study how organisms react to a certain situation with a given behavior. In this sense, the capacity to solve problems not through existing habits but through creative new approaches
8151-486: A reaction to particular external stimuli. This view implies that mental phenomena are not private internal states but are accessible to empirical observation like regular physical phenomena. Functionalism agrees that mental states do not depend on the exact internal constitution of the mind and characterizes them instead in regard to their functional role. Unlike behaviorism, this role is not limited to behavioral patterns but includes other factors as well. For example, part of
8398-519: A regular language, like English or French, but has its own type of language with the corresponding symbols and syntax. This theory is known as the language of thought hypothesis . Inner speech theory has a strong initial plausibility since introspection suggests that indeed many thoughts are accompanied by inner speech. But its opponents usually contend that this is not true for all types of thinking. It has been argued, for example, that forms of daydreaming constitute non-linguistic thought. This issue
8645-470: A regular wall can be understood as computing an algorithm since they are "isomorphic to the formal structure of the program" in question under the right interpretation. This would lead to the implausible conclusion that the wall is thinking. Another objection focuses on the idea that computationalism captures only some aspects of thought but is unable to account for other crucial aspects of human cognition. A great variety of types of thinking are discussed in
8892-427: A representation of the world and the objects within it. This complex process underlying perceptual experience is shaped by many factors, including the individual's past experiences , cultural background, beliefs, knowledge, and expectations. Memory is the mechanism of storing and retrieving information. Episodic memory handles information about specific past events in one's life and makes this information available in
9139-428: A role in judgments on the morality of abortion . Some Christians espouse a trichotomic view of humans, which characterizes humans as consisting of a body ( soma ), soul ( psyche ), and spirit ( pneuma ); however, the majority of modern Bible scholars point out how the concepts of "spirit" and of "soul" are used interchangeably in many biblical passages, and so hold to dichotomy: the view that each human comprises
9386-432: A shadow. In some cases, it is connected to shamanistic beliefs among the various Inuit groups . Caribou Inuit groups also believed in several types of souls. Shinto distinguishes between the souls of living persons ( tamashii ) and those of dead persons ( mitama ), each of which may have different aspects or sub-souls. Sikhism considers soul ( atma ) to be part of God ( Waheguru ). Various hymns are cited from
9633-435: A solution, or of heuristics : rules that are understood but that do not always guarantee solutions. Cognitive science differs from cognitive psychology in that algorithms that are intended to simulate human behavior are implemented or implementable on a computer. In other instances, solutions may be found through insight, a sudden awareness of relationships. Soul In many religious and philosophical traditions,
9880-399: A specific direction to obtain what he or she wants. The question, then, is how it can be possible for conscious experiences to arise out of a lump of gray matter endowed with nothing but electrochemical properties. A related problem is to explain how someone's propositional attitudes (e.g. beliefs and desires) can cause that individual's neurons to fire and his muscles to contract in exactly

After giving the pairs time to interact, it is assessed whether the members of similar pairs have more positive attitudes toward one another than the members of dissimilar pairs. Thought Various theories of thinking have been proposed, some of which aim to capture the characteristic features of thought. Platonists hold that thinking consists in discerning and inspecting Platonic forms and their interrelations. It involves

Some of the difficulties of assessing animal minds are also reflected in the topic of artificial minds, that is, the question of whether computer systems implementing artificial intelligence should be considered a form of mind. This idea is consistent with some theories of the nature of mind, such as functionalism and its idea that mental concepts describe functional roles, which are implemented by biological brains but could in principle also be implemented by artificial devices. The Turing test
10868-440: A symbol from a cell, writing a symbol to a cell, and executing instructions based on the symbols read. This way it is possible to perform deductive reasoning following the inference rules of formal logic as well as simulating many other functions of the mind, such as language processing, decision making, and motor control. But computationalism does not only claim that thinking is in some sense similar to computation. Instead, it
11115-469: A symbolic process aimed at making sense of them, organizing their information, and deciding how to respond. Logical reasoning is a form of thinking that starts from a set of premises and aims to arrive at a conclusion supported by these premises. This is the case when deducing that "Socrates is mortal" from the premises "Socrates is a man" and "all men are mortal". Problem-solving is a closely related process that consists of several steps, such as identifying
11362-580: A therapist to change patterns of thinking, feeling, and acting. Psychoanalysis aims to help patients resolve conflicts between the conscious and the unconscious mind. Cognitive behavioral therapy focuses on conscious mental phenomena to identify and change irrational beliefs and negative thought patterns. Behavior therapy , a related approach, relies on classical conditioning to unlearn harmful behaviors. Humanistic therapies try to help people gain insight into their self-worth and empower them to resolve their problems. Drug therapies use medication to alter
11609-592: A time, either starting at the beginning and moving forward or starting at the end and moving backward. So when planning a trip, one could plan the different stages of the trip from origin to destiny in the chronological order of how the trip will be realized, or in the reverse order. Obstacles to problem solving can arise from the thinker's failure to take certain possibilities into account by fixating on one specific course of action. There are important differences between how novices and experts solve problems. For example, experts tend to allocate more time for conceptualizing
11856-552: A typical human concept of lifespan and time. According to Louis Ginzberg , the soul of Adam is the image of God . Every soul of human also escapes from the body every night, rises up to heaven, and fetches new life thence for the body of man. In Brahma Kumaris , human souls are believed to be incorporeal and eternal . God is considered to be the Supreme Soul, with maximum degrees of spiritual qualities, such as peace, love and purity. In Helena Blavatsky 's Theosophy ,
12103-582: A visit to the dentist. Another feature commonly ascribed to mental states is that they are private, meaning that others do not have this kind of direct access to a person's mental state and have to infer it from other observations, like the pain behavior of the person with the toothache. Some philosophers claim that knowledge of some or all mental states is infallible , for instance, that a person cannot be mistaken about whether they are in pain. A related view states that all mental states are either conscious or accessible to consciousness. According to this view, when
12350-470: A wide variety of states, such as perception, thinking, fantasizing, dreaming, and altered states of consciousness . In the case of phenomenal consciousness, the awareness involves a direct and qualitative experience of mental phenomena, like the auditory experience of attending a concert. Access consciousness, by contrast, refers to an awareness of information that is accessible to other mental processes but not necessarily part of current experience. For example,
12597-405: Is physicalism , also referred to as materialism , which states that everything is physical. According to eliminative physicalism , there are no mental phenomena, meaning that things like beliefs and desires do not form part of reality. Reductive physicalists defend a less radical position: they say that mental states exist but can, at least in principle, be completely described by physics without

For example, a belief is rational if it relies on strong supporting evidence and a decision is rational if it follows careful deliberation of all the relevant factors and outcomes. Mental states are irrational if they are not based on good reasons, such as beliefs caused by faulty reasoning, superstition , or cognitive biases , and decisions that give into temptations instead of following one's best judgment. Mental states that fall outside
13091-461: Is a central aspect of the mind–body problem: it is the challenge of explaining how physical states can give rise to conscious experience. Its main difficulty lies in the subjective and qualitative nature of consciousness, which is unlike typical physical processes. The hard problem of consciousness contrasts with the "easy problems" of explaining how certain aspects of consciousness function, such as perception, memory, or learning. Another approach to
13338-451: Is a dispositional belief. By activating the belief to consciously think about it or use it in other cognitive processes, it becomes occurrent until it is no longer actively considered or used. The great majority of a person's beliefs are dispositional most of the time. Traditionally, the mind was subdivided into mental faculties understood as capacities to perform certain functions or bring about certain processes. An influential subdivision in

Positive thinking involves focusing one's attention on the positive aspects of one's situation and is intimately related to optimism . The terms "thought" and "thinking" refer to a wide variety of psychological activities. In their most common sense, they are understood as conscious processes that can happen independently of sensory stimulation. This includes various different mental processes, like considering an idea or proposition or judging it to be true. In this sense, memory and imagination are forms of thought but perception
13832-512: Is a traditionally influential procedure to test artificial intelligence: a person exchanges messages with two parties, one of them a human and the other a computer. The computer passes the test if it is not possible to reliably tell which party is the human and which one is the computer. While there are computer programs today that may pass the Turing test, this alone is usually not accepted as conclusive proof of mindedness. For some aspects of mind, it
14079-493: Is acquired and information processed. The intellect is one mental capacity responsible for thought, reasoning, and understanding and is closely related to intelligence as the ability to acquire, understand, and apply knowledge. The brain is the physical organ responsible for most or all mental functions. The modern English word mind originates from the Old English word gemynd , meaning "memory". This term gave rise to
14326-426: Is an aspect of other mental processes in which mental resources like awareness are directed towards certain features of experience and away from others. This happens when a driver focuses on the traffic while ignoring billboards on the side of the road. Attention can be controlled voluntarily in the pursuit of specific goals but can also occur involuntarily when a strong stimulus captures a person's attention. Attention
14573-454: Is an entity or "spiritual spark" or "light" in the human body - because of which the body can sustain life. On the departure of this entity from the body, the body becomes lifeless – no amount of manipulations to the body can make the person make any physical actions. The soul is the "driver" in the body. It is the roohu or spirit or atma , the presence of which makes the physical body alive. Many religious and philosophical traditions support
14820-582: Is an internal state that propels individuals to initiate, continue, or terminate goal-directed behavior. It is responsible for the formation of intentions to perform actions and affects what goals someone pursues, how much effort they invest in the activity, and how long they engage in it. Motivation is affected by emotions, which are temporary experiences of positive or negative feelings like joy or anger. They are directed at and evaluate specific events, persons, or situations. They usually come together with certain physiological and behavioral responses. Attention

The terms "thought" and "thinking" can also be used to refer not to the mental processes themselves but to mental states or systems of ideas brought about by these processes. In this sense, they are often synonymous with the term "belief" and its cognates and may refer to

Therefore, Judaism embraces the commemoration of the day of one's death, nahala / Yahrtzeit , and not the birthday , as a festivity of remembrance, for only toward the end of life's struggles, tests and challenges could human souls be judged and credited for righteousness. Judaism places great importance on the study of the souls. Kabbalah and other mystic traditions go into greater detail into

The soul acts as a link between the material body and the spiritual self, and therefore shares some characteristics of both. The soul can be attracted either towards the spiritual or towards the material realm, being thus the battlefield of good and evil. It

Computationalist theories of thought are sometimes divided into functionalist and representationalist approaches. Functionalist approaches define mental states through their causal roles but allow both external and internal events in their causal network. Thought may be seen as a form of program that can be executed in

The long multiplication usually taught in school is an example of an algorithm for solving the problem of multiplying big numbers. Heuristics, on the other hand, are informal procedures. They are rough rules-of-thumb that tend to bring the thinker closer to the solution but success is not guaranteed in every case even if followed correctly. Examples of heuristics are working forward and working backward. These approaches involve planning one step at

Inner speech theories claim that thinking is a form of inner speech in which words are silently expressed in the thinker's mind. According to some accounts, this happens in a regular language, like English or French. The language of thought hypothesis , on the other hand, holds that this happens in

Present-day cognates include Dutch ziel and German Seele . In Judaism and in some Christian denominations, only human beings have immortal souls. Immortality
17043-419: Is commonly acknowledged today that animals have some form of mind, but it is controversial to which animals this applies and how their mind differs from the human mind. Different conceptions of the mind lead to different responses to this problem; when understood in a very wide sense as the capacity to process information, the mind is present in all forms of life, including insects, plants, and individual cells; on

This problem is often discussed through the contrast between weak and strong artificial intelligence. Weak or narrow artificial intelligence is limited to specific mental capacities or functions. It focuses on a particular task or a narrow set of tasks, like autonomous driving , speech recognition , or theorem proving . The goal of strong AI, also termed artificial general intelligence ,

Some, following John Calvin , believe that the soul persists as consciousness after death. Others, following Martin Luther , believe that the soul dies with the body , and is unconscious ("sleeps") until the resurrection of

In King Alfred 's translation of De Consolatione Philosophiae , it is used to refer to the immaterial, spiritual, or thinking aspect of a person, as contrasted with the person's physical body; in the Vespasian Psalter 77.50, it means "life" or "animate existence". The Old English word
18031-518: Is difficult to directly examine, manipulate, and measure it. Trying to circumvent this problem by investigating the brain comes with new challenges of its own, mainly because of the brain's complexity as a neural network consisting of billions of neurons, each with up to 10,000 links to other neurons. Psychology is the scientific study of mind and behavior. It investigates conscious and unconscious mental phenomena, including perception, memory, feeling, thought, decision, intelligence , and personality . It
18278-531: Is disputed within Judaism and the concept of immortality was most likely influenced by Plato . For example, Thomas Aquinas , borrowing directly from Aristotle 's On the Soul , attributed "soul" ( anima ) to all organisms but argued that only human souls are immortal. Other religions (most notably Hinduism and Jainism ) believe that all living things from the smallest bacterium to the largest of mammals are

It is sometimes argued that the experience of truth is central to thinking, i.e. that thinking aims at representing how the world is. It shares this feature with perception but differs from it in the way how it represents the world: without the use of sensory contents. One of

Psychology is a wide discipline that includes many subfields. Cognitive psychology is interested in higher-order mental activities like thinking, problem-solving, reasoning, and concept formation. Biological psychology seeks to understand
19019-441: Is imagism. It states that thinking involves entertaining a sequence of images where earlier images conjure up later images based on the laws of association. One problem with this view is that we can think about things that we cannot imagine. This is especially relevant when the thought involves very complex objects or infinities, which is common, for example, in mathematical thought. One criticism directed at associationism in general
19266-431: Is immortal, and eternal, and capable of receiving a fulness of joy. Latter-day Saint cosmology also describes "intelligences" as the essence of consciousness or agency. These are co-eternal with God, and animate the spirits. The union of a newly-created spirit body with an eternally-existing intelligence constitutes a "spirit birth", and justifies God's title "Father of our spirits". Some Confucian traditions contrast

He argues in favor of this claim by holding that it constitutes the best explanation of the characteristic features of thinking. One of these features is productivity : a system of representations is productive if it can generate an infinite number of unique representations based on
19760-431: Is in an important sense similar to hearing sounds, it involves the use of language and it constitutes a motor plan that could be used for actual speech. This connection to language is supported by the fact that thinking is often accompanied by muscle activity in the speech organs. This activity may facilitate thinking in certain cases but is not necessary for it in general. According to some accounts, thinking happens not in
20007-596: Is in this stele". It is one of the earliest references to a soul as a separate entity from the body. The 800-pound (360 kg) basalt stele is 3 ft (0.91 m) tall and 2 ft (0.61 m) wide. It was uncovered in the third season of excavations by the Neubauer Expedition of the Oriental Institute in Chicago, Illinois. The Baháʼí Faith affirms that "the soul is a sign of God,
20254-537: Is known as cognitivism , which is interested in how people mentally represent information processing. It had its foundations in the Gestalt psychology of Max Wertheimer , Wolfgang Köhler , and Kurt Koffka , and in the work of Jean Piaget , who provided a theory of stages/phases that describes children's cognitive development. Cognitive psychologists use psychophysical and experimental approaches to understand, diagnose, and solve problems, concerning themselves with
20501-456: Is light cannot be dark. Therefore, feathers cannot be dark". An important aspect of fallacies is that they seem to be rationally compelling on the first look and thereby seduce people into accepting and committing them. Whether an act of reasoning constitutes a fallacy does not depend on whether the premises are true or false but on their relation to the conclusion and, in some cases, on the context. Concepts are general notions that constitute
20748-426: Is more basic or fundamental since predicative experience is in some sense built on top of it and therefore depends on it. Another way how phenomenologists have tried to distinguish the experience of thinking from other types of experiences is in relation to empty intentions in contrast to intuitive intentions . In this context, "intention" means that some kind of object is experienced. In intuitive intentions ,
20995-427: Is mortal". Other theories of judgment focus more on the relation between the judged proposition and reality. According to Franz Brentano , a judgment is either a belief or a disbelief in the existence of some entity. In this sense, there are only two fundamental forms of judgment: "A exists" and "A does not exist". When applied to the sentence "all men are mortal", the entity in question is "immortal men", of whom it
21242-407: Is no beginning or end to the existence of soul. It is eternal in nature and changes its form until it attains liberation. In Jainism, jiva is the immortal essence or soul of a living organism, such as human, animal, fish, or plant, which survives physical death. The concept of Ajiva in Jainism means "not soul", and represents matter (including body), time, space, non-motion and motion. In Jainism,
21489-414: Is no good alternative explanation. Some arguments against the language of thought hypothesis are based on neural networks, which are able to produce intelligent behavior without depending on representational systems. Other objections focus on the idea that some mental representations happen non-linguistically, for example, in the form of maps or images. Computationalists have been especially interested in
21736-422: Is not clear what steps need to be taken, i.e. there is no clear formula that would lead to success if followed correctly. In this case, the solution may sometimes come in a flash of insight in which the problem is suddenly seen in a new light. Another way to categorize different forms of problem solving is by distinguishing between algorithms and heuristics . An algorithm is a formal procedure in which each step
21983-454: Is not. In a more restricted sense, only the most paradigmatic cases are considered thought. These involve conscious processes that are conceptual or linguistic and sufficiently abstract, like judging, inferring, problem solving, and deliberating. Sometimes the terms "thought" and "thinking" are understood in a very wide sense as referring to any form of mental process, conscious or unconscious. In this sense, they may be used synonymously with
22230-467: Is of greatest value in [them], that by which [they are] most especially in God's image: 'soul' signifies the spiritual principle in [humanity]." All souls living and dead will be judged by Jesus Christ when he comes back to earth . The Catholic Church teaches that the existence of each individual soul is dependent wholly upon God, stating: "The doctrine of the faith affirms that the spiritual and immortal soul
22477-407: Is often combined with the language of thought hypothesis by interpreting these sequences as symbols whose order is governed by syntactic rules. Various arguments have been raised against computationalism. In one sense, it seems trivial since almost any physical system can be described as executing computations and therefore as thinking. For example, it has been argued that the molecular movements in
22724-451: Is one form of non-deductive reasoning, for example, when one concludes that "the sun will rise tomorrow" based on one's experiences of all the previous days. Other forms of non-deductive reasoning include the inference to the best explanation and analogical reasoning . Fallacies are faulty forms of thinking that go against the norms of correct reasoning. Formal fallacies concern faulty inferences found in deductive reasoning. Denying
22971-626: Is only when the soul is attracted towards the spiritual and merges with the Self that it becomes eternal and divine. Rudolf Steiner claimed classical trichotomic stages of soul development, which interpenetrated one another in consciousness: In Surat Shabda Yoga , the soul is considered to be an exact replica and spark of the Divine. The purpose of Surat Shabd Yoga is to realize one's True Self as soul (Self-Realisation), True Essence (Spirit-Realisation) and True Divinity (God-Realisation) while living in
23218-422: Is outperformed by unconscious thought when complex problems with many variables are involved. This is sometimes explained through the claim that the number of items one can consciously think about at the same time is rather limited whereas unconscious thought lacks such limitations. But other researchers have rejected the claim that unconscious thought is often superior to conscious thought. Other suggestions for
23465-431: Is particularly relevant. The term "behaviorism" is also sometimes used in a slightly different sense when applied to thinking to refer to a specific form of inner speech theory. This view focuses on the idea that the relevant inner speech is a derivative form of regular outward speech. This sense overlaps with how behaviorism is understood more commonly in philosophy of mind since these inner speech acts are not observed by
23712-408: Is relevant to learning, which is the ability of the mind to acquire new information and permanently modify its understanding and behavioral patterns. Individuals learn by undergoing experiences, which helps them adapt to the environment. An influential distinction is between conscious and unconscious mental processes. Consciousness is the awareness of external and internal circumstances. It encompasses
23959-421: Is relevant to the question of whether animals have the capacity to think. If thinking is necessarily tied to language then this would suggest that there is an important gap between humans and animals since only humans have a sufficiently complex language. But the existence of non-linguistic thoughts suggests that this gap may not be that big and that some animals do indeed think. There are various theories about
24206-401: Is said that they do not exist. Important for Brentano is the distinction between the mere representation of the content of the judgment and the affirmation or the denial of the content. The mere representation of a proposition is often referred to as "entertaining a proposition". This is the case, for example, when one considers a proposition but has not yet made up one's mind about whether it
24453-409: Is said to be one whose souls are in harmony with each other, while an evil person is one whose souls are in conflict. The "free soul" is said to leave the body and journey to the spirit world during sleep, trance-like states , delirium , insanity , and death. The duality is also seen in the healing traditions of Austronesian shamans, where illnesses are regarded as a " soul loss " and thus to heal
24700-399: Is said to have mental illness or unconsciousness , while a dead soul may reincarnate to a disability , lower desire realms , or may even be unable to reincarnate. In theological reference to the soul, the terms "life" and "death" are viewed as emphatically more definitive than the common concepts of " biological life " and "biological death". Because the soul is said to be transcendent of
24947-404: Is said. Other arguments for the experience of thinking focus on the direct introspective access to thinking or on the thinker's knowledge of their own thoughts. Phenomenologists are also concerned with the characteristic features of the experience of thinking. Making a judgment is one of the prototypical forms of cognitive phenomenology. It involves epistemic agency, in which a proposition
25194-411: Is that its claim is too far-reaching. There is wide agreement that associative processes as studied by associationists play some role in how thought unfolds. But the claim that this mechanism is sufficient to understand all thought or all mental processes is usually not accepted. According to behaviorism , thinking consists in behavioral dispositions to engage in certain publicly observable behavior as
25441-422: Is the belief that humans have two or more souls, generally termed the "body soul", or "life soul", and the "free soul". The former is linked to bodily functions and awareness when awake, while the latter can freely wander during sleep or trance states. In some cases, there are a plethora of soul types with different functions. Soul dualism and multiple souls are prominent in the traditional animistic beliefs of
25688-412: Is the mark of the mental. A state is intentional if it refers to or represents something. For example, if a person perceives a piano or thinks about it then the mental state is intentional because it refers to a piano. This view distinguishes between original and derivative intentionality. Mental states have original intentionality while some non-mental phenomena have derivative intentionality. For instance,
25935-440: Is the process of interpreting and organizing sensory information to become acquainted with the environment. This information is acquired through sense organs receptive to various types of physical stimuli , which correspond to different forms of perception, such as vision , hearing , touch , smell , and taste . The sensory information received this way is a form of raw data that is filtered and processed to actively construct
26182-468: Is the totality of psychological phenomena and capacities, encompassing consciousness , thought , perception , feeling , mood , motivation , behavior , memory , and learning . The term is sometimes used in a more narrow sense to refer only to higher or more abstract cognitive functions associated with reasoning and awareness . Minds were traditionally conceived as immaterial substances or independent entities and contrasted with matter and body . In
26429-451: Is thought that happens in the background without being experienced. It is therefore not observed directly. Instead, its existence is usually inferred by other means. For example, when someone is faced with an important decision or a difficult problem, they may not be able to solve it straight away. But then, at a later time, the solution may suddenly flash before them even though no conscious steps of thinking were taken towards this solution in
26676-526: Is to create a complete artificial person that has all the mental capacities of humans, including consciousness, emotion, and reason. It is controversial whether strong AI is possible; influential arguments against it include John Searle 's Chinese Room Argument and Hubert Dreyfus 's critique based on Heideggerian philosophy. Mental health is a state of mind characterized by internal equilibrium and well-being in which mental capacities function as they should. Some theorists emphasize positive features such as
26923-440: Is to explain how humans can learn and think about Platonic forms belonging to a different realm. Plato himself tries to solve this problem through his theory of recollection, according to which the soul already was in contact with the Platonic forms before and is therefore able to remember what they are like. But this explanation depends on various assumptions usually not accepted in contemporary thought. Aristotelians hold that
27170-438: Is to realize that one's true self ( ātman ) is identical with the transcendent self Brahman according to Advaita Vedanta . The six orthodox schools of Hinduism believe that there is ātman (self, essence) in every being. In Hinduism and Jainism , a jiva ( Sanskrit : जीव , jīva , alternative spelling jiwa ; Hindi : जीव , jīv , alternative spelling jeev ) is a living being, or any entity imbued with
27417-429: Is true or false. The term "thinking" can refer both to judging and to mere entertaining. This difference is often explicit in the way the thought is expressed: "thinking that" usually involves a judgment whereas "thinking about" refers to the neutral representation of a proposition without an accompanying belief. In this case, the proposition is merely entertained but not yet judged . Some forms of thinking may involve
27664-443: The material existence, and is said to have (potentially) eternal life , the death of the soul is likewise said to be an eternal death . Thus, in the concept of divine judgment , God is commonly said to have options with regard to the dispensation of souls, ranging from Heaven (i.e., angels ) to hell (i.e., demons ), with various concepts in between. Typically both Heaven and hell are said to be eternal, or at least far beyond
27911-644: The Austronesian peoples , the Chinese people ( hún and pò ), the Tibetan people , most African peoples, most Native North Americans , ancient South Asian peoples, Northern Eurasian peoples, and in Ancient Egyptians (the ka and ba ). The belief in soul dualism is found throughout most Austronesian shamanistic traditions. The reconstructed Proto-Austronesian word for
28158-865: The Middle English words mind(e) , münd(e) , and mend(e) , resulting in a slow expansion of meaning to cover all mental capacities. The original meaning is preserved in expressions like call to mind and keep in mind . Cognates include the Old High German gimunt , the Gothic gamunds , the ancient Greek μένος , the Latin mens , and the Sanskrit manas . The mind encompasses many phenomena, including perception , memory , thought , imagination , motivation , emotion , attention , learning , and consciousness . Perception
28405-470: The history of philosophy was between the faculties of intellect and will . The intellect encompasses mental phenomena aimed at understanding the world and determining what to believe or what is true; the will is concerned with practical matters and what is good, reflected in phenomena like desire, decision-making, and action. The exact number and nature of the mental faculties are disputed and more fine-grained subdivisions have been proposed, such as dividing
28652-412: The soul is the non-material essence of a person, which includes one's identity , personality , and memories , an immaterial aspect or essence of a living being that is believed to be able to survive physical death . The concept of the soul is generally applied to humans, although it can also be applied to other living or even non-living entities, as in animism . The Modern English noun soul
28899-426: The visual and the auditory areas . A central function of the hippocampus is the formation and retrieval of long-term memories. It belongs to the limbic system , which plays a key role in the regulation of emotions through the amygdala . The motor cortex is responsible for planning, executing, and controlling voluntary movements. Broca's area is a separate region dedicated to speech production . The activity of
29146-522: The "body soul" is *nawa ("breath", "life", or "vital spirit"). It is located somewhere in the abdominal cavity , often in the liver or the heart (Proto-Austronesian *qaCay ). The "free soul" is located in the head. Its names are usually derived from Proto-Austronesian *qaNiCu ("ghost", "spirit [of the dead]"), which also apply to other non-human nature spirits. The "free soul" is also referred to in names that literally mean "twin" or "double", from Proto-Austronesian *duSa ("two"). A virtuous person
29393-456: The "mark of the mental", that is, the criteria that distinguish mental from non-mental phenomena. Epistemic criteria say that the unique feature of mental states is how people know about them. For example, if a person has a toothache, they have direct or non-inferential knowledge that they are in pain. But they do not have this kind of knowledge of the physical causes of the pain and may have to consult external evidence through visual inspection or
29640-756: The Jewish notions of nephesh (נפש) and ruah (רוח), meaning spirit, (also in the Septuagint, e.g. Genesis 1:2 רוּחַ אֱלֹהִים = πνεῦμα θεοῦ = spiritus Dei = "the Spirit of God"). Christians generally believe in the existence and eternal, infinite nature of the soul. The "origin of the soul" has provided a vexing question in Christianity. The major theories put forward include soul creationism , traducianism , and pre-existence . According to soul creationism, God creates each individual soul directly, either at
29887-418: The abilities of a person to realize their potential, express and modulate emotions, cope with adverse life situations, and fulfill their social role. Negative definitions, by contrast, see mental health as the absence of mental illness in the form of mental disorders . Mental disorders are abnormal patterns of thought, emotion, or behavior that deviate not only from how a mental capacity works on average but from
30134-433: The ability to discriminate between the pure Platonic forms themselves and the mere imitations found in the sensory world. According to Aristotelianism , to think about something is to instantiate in one's mind the universal essence of the object of thought. These universals are abstracted from sense experience and are not understood as existing in a changeless intelligible world, in contrast to Platonism. Conceptualism
30381-514: The ability to draw inferences from this concept to related concepts. Concept formation corresponds to acquiring these abilities. It has been suggested that animals are also able to learn concepts to some extent, due to their ability to discriminate between different types of situations and to adjust their behavior accordingly. In the case of problem solving , thinking aims at reaching a predefined goal by overcoming certain obstacles. This process often involves two different forms of thinking. On
30628-491: The academic literature. A common approach divides them into those forms that aim at the creation of theoretical knowledge and those that aim at producing actions or correct decisions, but there is no universally accepted taxonomy summarizing all these types. Thinking is often identified with the act of judging . A judgment is a mental operation in which a proposition is evoked and then either affirmed or denied. It involves deciding what to believe and aims at determining whether
30875-443: The antecedent is one type of formal fallacy, for example, "If Othello is a bachelor, then he is male. Othello is not a bachelor. Therefore, Othello is not male". Informal fallacies , on the other hand, apply to all types of reasoning. The source of their flaw is to be found in the content or the context of the argument. This is often caused by ambiguous or vague expressions in natural language , as in "Feathers are light. What
31122-416: The body are the soul of man." Latter-day Saints believe that the soul is the union of a pre-existing, God-made spirit, and a temporal body, which is formed by physical conception on earth. After death, the spirit continues to live and progress in the spirit world until the resurrection , when it is reunited with the body that once housed it. This reuniting of body and spirit results in a perfect soul that
31369-445: The body is a collection of elements and the soul is the essence. Soul or psyche ( Ancient Greek : ψυχή psykhḗ , of ψύχειν psýkhein , "to breathe", cf. Latin anima ) comprises the mental abilities of a living being: reason, character, free will , feeling, consciousness , qualia , memory, perception, thinking, and so on. Depending on the philosophical system, a soul can either be mortal or immortal . The ancient Greeks used
31616-402: The body. Human perceptual experiences depend on stimuli which arrive at one's various sensory organs from the external world and these stimuli cause changes in one's mental state, ultimately causing one to feel a sensation, which may be pleasant or unpleasant. Someone's desire for a slice of pizza, for example, will tend to cause that person to move his or her body in a specific manner and in
31863-427: The brain chemistry involved in the disorder through substances like antidepressants , antipsychotics , mood stabilizers , and anxiolytics . Various fields of inquiry study the mind, including psychology, neuroscience, philosophy, and cognitive science. They differ from each other in the aspects of mind they investigate and the methods they employ in the process. The study of the mind poses various problems since it
32110-447: The characteristic features of thinking. The theories listed here are not exclusive: it may be possible to combine some without leading to a contradiction. According to Platonism , thinking is a spiritual activity in which Platonic forms and their interrelations are discerned and inspected. This activity is understood as a form of silent inner speech in which the soul talks to itself. Platonic forms are seen as universals that exist in
32357-429: The characteristic features often ascribed to thinking and judging is that they are predicative experiences, in contrast to the pre-predicative experience found in immediate perception. On such a view, various aspects of perceptual experience resemble judgments without being judgments in the strict sense. For example, the perceptual experience of the front of a house brings with it various expectations about aspects of
32604-435: The cognitive level, maladaptive beliefs and patterns of thought can be responsible. Environmental factors involve cultural influences and social events that may trigger the onset of a disorder. There are various approaches to treating mental disorders, and the most suitable treatment usually depends on the type of disorder, its cause, and the individual's overall condition. Psychotherapeutic methods use personal interaction with
32851-482: The concept of mental modules is normally used to provide a more limited explanation restricted to certain low-level cognitive processes without trying to explain how they are integrated into higher-level processes such as conscious reasoning. Many low-level cognitive processes responsible for visual perception have this automatic and unconscious nature. In the case of visual illusions like the Müller-Lyer illusion ,
33098-482: The consumption of psychoactive drugs , like caffeine, antidepressants , alcohol, and psychedelics , temporarily affects brain chemistry with diverse effects on the mind, ranging from increased attention to mood changes, impaired cognitive functions, and hallucinations . Long-term changes to the brain in the form of neurodegenerative diseases and brain injuries can lead to permanent alterations in mental functions. Alzheimer's disease in its first stage deteriorates
33345-436: The contemporary discourse, they are more commonly seen as features of other entities and are often understood as capacities of material brains. The precise definition of mind is disputed and while it is generally accepted that some non-human animals also have mind, there is no agreement on where exactly the boundary lies. Despite these disputes, there is wide agreement that mind plays a central role in most aspects of human life as
33592-418: The contemporary discourse. The mind plays a central role in most aspects of human life but its exact nature is disputed. Some characterizations focus on internal aspects, saying that the mind is private and transforms information. Others stress its relation to outward conduct, understanding mental phenomena as dispositions to engage in observable behavior. The mind–body problem is the challenge of explaining
33839-415: The correct manner. These comprise some of the puzzles that have confronted epistemologists and philosophers of mind from at least the time of René Descartes . The above reflects a classical, functional description of how we work as cognitive, thinking systems. However the apparently irresolvable mind–body problem is said to be overcome, and bypassed, by the embodied cognition approach, with its roots in
34086-440: The dead . Various new religious movements deriving from Adventism including Christadelphians , Seventh-day Adventists , and Jehovah's Witnesses , similarly believe that the dead do not possess a soul separate from the body and are unconscious until the resurrection. The Church of Jesus Christ of Latter-day Saints teaches that the spirit and body together constitute the Soul of Man (Mankind), stating: "The spirit and
34333-429: The development of mind before birth, such as nutrition, maternal stress, and exposure to harmful substances like alcohol during pregnancy. Early childhood is marked by rapid developments as infants learn voluntary control over their bodies and interact with their environment on a basic level. Typically after about one year, this covers abilities like walking, recognizing familiar faces, and producing individual words. On
34580-413: The difference between the two forms of thinking include that conscious thought tends to follow formal logical laws while unconscious thought relies more on associative processing and that only conscious thinking is conceptually articulated and happens through the medium of language. Phenomenology is the science of the structure and contents of experience . The term "cognitive phenomenology" refers to
34827-418: The different areas is additionally influenced by neurotransmitters , which are signaling molecules that enhance or inhibit different types of neural communication. For example, dopamine influences motivation and pleasure while serotonin affects mood and appetite. The close interrelation of brain processes and the mind is seen by the effect that physical changes of the brain have on the mind. For instance,
35074-459: The domain of rational evaluation are arational rather than irrational. There is controversy regarding which mental phenomena lie outside this domain; suggested examples include sensory impressions, feelings, desires, and involuntary responses. Another contrast is between dispositional and occurrent mental states. A dispositional state is a power that is not exercised. If a person believes that cats have whiskers but does not think about this fact, it
35321-488: The earliest forms of life 4 to 3.5 billion years ago, like the abilities of bacteria and eukaryotic unicellular organisms to sense the environment, store this information, and react to it. Nerve cells emerged with the development of multicellular organisms more than 600 million years ago as a way to process and transmit information. About 600 to 550 million years ago, an evolutionary bifurcation happened into radially symmetric organisms with ring-shaped nervous systems or
35568-444: The emotional and social levels, they develop attachments with their primary caretakers and express emotions ranging from joy to anger, fear, and surprise. An influential theory by Jean Piaget divides the cognitive development of children into four stages. The sensorimotor stage from birth until two years is concerned with sensory impressions and motor activities while learning that objects remain in existence even when not observed. In
35815-404: The empiricist tradition has been associationism , the view that thinking consists in the succession of ideas or images. This succession is seen as being governed by laws of association, which determine how the train of thought unfolds. These laws are different from logical relations between the contents of thoughts, which are found in the case of drawing inferences by moving from the thought of
36062-404: The environment. According to this view, mental states and their contents are at least partially determined by external circumstances. For example, some forms of content externalism hold that it can depend on external circumstances whether a belief refers to one object or another. The extended mind thesis states that external circumstances not only affect the mind but are part of it, like a diary or
36309-422: The evolution of vertebrates, their brains tended to grow and the specialization of the different brain areas tended to increase. These developments are closely related to changes in limb structures, sense organs, and living conditions with a close correspondence between the size of a brain area and the importance of its function to the organism. An important step in the evolution of mammals about 200 million years ago
36556-472: The evolutionary processes responsible for human intelligence have been proposed. The social intelligence hypothesis says that the evolution of the human mind was triggered by the increased importance of social life and its emphasis on mental abilities associated with empathy , knowledge transfer , and meta-cognition . According to the ecological intelligence hypothesis, the main value of the increased mental capacities comes from their advantages in dealing with
36803-508: The experiential character of thinking or what it feels like to think. Some theorists claim that there is no distinctive cognitive phenomenology. On such a view, the experience of thinking is just one form of sensory experience. According to one version, thinking just involves hearing a voice internally. According to another, there is no experience of thinking apart from the indirect effects thinking has on sensory experience. A weaker version of such an approach allows that thinking may have
37050-402: The forebrain. The primary operation of many of the main mental phenomena is located in specific areas of the forebrain. The prefrontal cortex is responsible for executive functions , such as planning, decision-making, problem-solving, and working memory. The role of the sensory cortex is to process and interpret sensory information, with different subareas dedicated to different senses, like
37297-421: The functional role of pain is given by its relation to bodily injury and its tendency to cause behavioral patterns like moaning and other mental states, like a desire to stop the pain. Computationalism , a similar theory prominent in cognitive science, defines minds in terms of cognitions and computations as information processors. Theories under the umbrella of externalism emphasize the mind's dependency on
37544-399: The fundamental building blocks of thought. They are rules that govern how objects are sorted into different classes. A person can only think about a proposition if they possess the concepts involved in this proposition. For example, the proposition " wombats are animals" involves the concepts "wombat" and "animal". Someone who does not possess the concept "wombat" may still be able to read
37791-640: The hippocampus, reducing the ability to form new memories and recall existing ones. An often-cited case of the effects of brain injury is Phineas Gage , whose prefrontal cortex was severely damaged during a work accident when an iron rod pierced through his skull and brain. Gage survived the accident but his personality and social attitude changed significantly as he became more impulsive, irritable, and anti-social while showing little regard for social conventions and an impaired ability to plan and make rational decisions. Not all these changes were permanent and Gage managed to recover and adapt in some areas. The mind has
38038-560: The holy book Guru Granth Sahib (SGGS) that suggests this belief. "God is in the Soul and the Soul is in the God." The same concept is repeated at various pages of the SGGS. Example include that "The soul is divine; divine is the soul. Worship Him with love", and "The soul is the Lord, and the Lord is the soul; contemplating the Shabad, the Lord is found." The atma or soul according to Sikhism
38285-407: The house not directly seen, like the size and shape of its other sides. This process is sometimes referred to as apperception . These expectations resemble judgments and can be wrong. This would be the case when it turns out upon walking around the "house" that it is no house at all but only a front facade of a house with nothing behind it. In this case, the perceptual expectations are frustrated and
38532-508: The human body, and therefore ubiquitous and cannot be placed in a single organ, such as heart or brain, nor it is separable from the body (except after the body's death). In the fourth book of De Trinitate , Augustine of Hippo states that the soul is all in the whole body and all in any part of it. The present Catechism of the Catholic Church states that "[The term 'soul'] refers to the innermost aspect of [persons], that which
38779-540: The immortal rūḥ "drives" the mortal nafs, which comprises temporal desires and perceptions necessary for living. Several verses of the Quran that mention the rûh occur in chapters 17 ("The Night Journey") and 39 ("The Troops"). And they ask you, [O Muhammad], about the Rûh. Say, "The Rûh is of the affair of my Lord. And mankind has not been given of knowledge except a little. And remember your Rabb inside your-self Allah takes
39026-566: The impermanence of all things ( anitya ), and the suffering ( dukkha ) experienced by living beings due to attachment to ideas of self and permanence are central concepts in almost all Buddhist schools . The doctrine of Buddha-nature , while sometimes misinterpreted as referring to a "true self" or "soul" of some kind, actually depends upon acceptance of the concept of anatman to be properly understood. According to some Christian eschatology , when people die, their souls will be judged by God and determined to go to Heaven or to Hades awaiting
39273-482: The increased human mental capacities as a matter of degree rather than kind. Central considerations for this position are the shared evolutionary origin, organic similarities on the level of brain and nervous system, and observable behavior, ranging from problem-solving skills, animal communication , and reactions to and expressions of pain and pleasure. Of particular importance are the questions of consciousness and sentience , that is, to what extent non-human animals have
39520-498: The individual changes vary from person to person as a form of learning from experience, like forming specific memories or acquiring particular behavioral patterns. Others are more universal developments as psychological stages that all or most humans go through as they pass through early childhood , adolescence , adulthood , and old age . These developments cover various areas, including intellectual, sensorimotor, linguistic, emotional, social, and moral developments. Some factors affect
39767-449: The individual. Psychoanalytic theory studies symptoms caused by this process and therapeutic methods to avoid them by making the repressed thoughts accessible to conscious awareness. Mental states are often divided into sensory and propositional states. Sensory states are experiences of sensory qualities, often referred to as qualia , like colors, sounds, smells, pains, itches, and hunger. Propositional states involve an attitude towards
40014-490: The information stored in a memory may be accessible when drawing conclusions or guiding actions even when the person is not explicitly thinking about it. Unconscious or nonconscious mental processes operate without the individual's awareness but can still influence mental phenomena on the level of thought, feeling, and action. Some theorists distinguish between preconscious, subconscious, and unconscious states depending on their accessibility to conscious awareness. When applied to
40261-466: The intellect into the faculties of understanding and judgment or adding sensibility as an additional faculty responsible for sensory impressions. In contrast to the traditional view, more recent approaches analyze the mind in terms of mental modules rather than faculties. A mental module is an inborn system of the brain that automatically performs a particular function within a specific domain without conscious awareness or effort. In contrast to faculties,
40508-464: The judged proposition is true or false. Various theories of judgment have been proposed. The traditionally dominant approach is the combination theory. It states that judgments consist in the combination of concepts. On this view, to judge that "all men are mortal" is to combine the concepts "man" and "mortal". The same concepts can be combined in different ways, corresponding to different forms of judgment, for example, as "some men are mortal" or "no man
40755-467: The kitchen. This way, a perception can confirm or refute a thought depending on whether the empty intuitions are later fulfilled or not. The mind–body problem concerns the explanation of the relationship that exists between minds , or mental processes, and bodily states or processes. The main aim of philosophers working in this area is to determine the nature of the mind and mental states/processes, and how—or even if—minds are affected by and can affect
41002-544: The language of thought hypothesis since it provides ways to close the gap between thought in the human brain and computational processes implemented by computers. The reason for this is that processes over representations that respect syntax and semantics, like inferences according to the modus ponens , can be implemented by physical systems using causal relations. The same linguistic systems may be implemented through different material systems, like brains or computers. In this way, computers can think . An important view in
41249-575: The level of semantics, the semantic content or the meaning of the compound representations should depend on the semantic contents of its constituents. A representational system is linguistically structured if it fulfills these two requirements. The language of thought hypothesis states that the same is true for thinking in general. This would mean that thought is composed of certain atomic representational constituents that can be combined as described above. Apart from this abstract characterization, no further concrete claims are made about how human thought
41496-459: The liberated and non-liberated souls is that the qualities and attributes are manifested completely in case of siddha (liberated soul) as they have overcome all the karmic bondages whereas in case of non-liberated souls they are partially exhibited. Souls who rise victorious over wicked emotions while still remaining within physical bodies are referred to as arihants . Concerning the Jain view of
41743-488: The limbs are active, but when one is sleeping, the soul is active and reveals "an award of joy or sorrow drawing near" in dreams. Erwin Rohde writes that an early pre- Pythagorean belief presented the soul as lifeless when it departed the body, and that it retired into Hades with no hope of returning to a body. Plato was the first thinker in antiquity to combine the various functions of the soul into one coherent conception:
41990-436: The logical form of thought. For example, to think that it will either rain or snow, it is not sufficient to instantiate the essences of rain and snow or to evoke the corresponding concepts. The reason for this is that the disjunctive relation between the rain and the snow is not captured this way. Another problem shared by these positions is the difficulty of giving a satisfying account of how essences or concepts are learned by
42237-555: The meantime. In such cases, the cognitive labor needed to arrive at a solution is often explained in terms of unconscious thoughts. The central idea is that a cognitive transition happened and we need to posit unconscious thoughts to be able to explain how it happened. It has been argued that conscious and unconscious thoughts differ not just concerning their relation to experience but also concerning their capacities. According to unconscious thought theorists , for example, conscious thought excels at simple problems with few variables but
42484-535: The medium of a unique mental language called Mentalese . Central to this idea is that linguistic representational systems are built up from atomic and compound representations and that this structure is also found in thought. Associationists understand thinking as the succession of ideas or images. They are particularly interested in the laws of association that govern how the train of thought unfolds. Behaviorists , by contrast, identify thinking with behavioral dispositions to engage in public intelligent behavior as
42731-415: The mental processes which mediate between stimulus and response. They study various aspects of thinking, including the psychology of reasoning , and how people make decisions and choices, solve problems, as well as engage in creative discovery and imaginative thought. Cognitive theory contends that solutions to problems either take the form of algorithms : rules that are not necessarily understood but promise
42978-426: The mental states which either belong to an individual or are common among a certain group of people. Discussions of thought in the academic literature often leave it implicit which sense of the term they have in mind. The word thought comes from Old English þoht , or geþoht , from the stem of þencan "to conceive of in the mind, consider". Various theories of thinking have been proposed. They aim to capture
43225-466: The mind alone will always leave us with the mind–body problem which cannot be solved. Psychologists have concentrated on thinking as an intellectual exertion aimed at finding an answer to a question or the solution of a practical problem. Cognitive psychology is a branch of psychology that investigates internal mental processes such as problem solving, memory, and language; all of which are used in thinking. The school of thought arising from this approach
43472-413: The mind include psychology , neuroscience , cognitive science , and philosophy . They tend to focus on different aspects of the mind and employ different methods of investigation, ranging from empirical observation and neuroimaging to conceptual analysis and thought experiments . The mind is relevant to many other fields, including epistemology , anthropology , religion, and education. The mind
43719-415: The mind is able to think about something by instantiating the essence of the object of thought. So while thinking about trees, the mind instantiates tree-ness. This instantiation does not happen in matter, as is the case for actual trees, but in mind, though the universal essence instantiated in both cases is the same. In contrast to Platonism, these universals are not understood as Platonic forms existing in
43966-445: The mind through abstraction. Inner speech theories claim that thinking is a form of inner speech . This view is sometimes termed psychological nominalism . It states that thinking involves silently evoking words and connecting them to form mental sentences. The knowledge a person has of their thoughts can be explained as a form of overhearing one's own silent monologue. Three central aspects are often ascribed to inner speech: it
44213-401: The minds of non-human animals are fundamentally different from human minds and often point to higher mental faculties, like thinking, reasoning, and decision-making based on beliefs and desires. This outlook is reflected in the traditionally influential position of defining humans as " rational animals " as opposed to all other animals. Continuity views, by contrast, emphasize similarities and see
44460-477: The moment of conception or at some later time. According to traducianism, the soul comes from the parents by natural generation. According to the preexistence theory, the soul exists before the moment of conception. There have been differing thoughts regarding whether human embryos have souls from conception, or whether there is a point between conception and birth where the fetus acquires a soul , consciousness , and / or personhood . Stances in this question play
44707-432: The most favorable one. Decision theory is a formal model of how ideal rational agents would make decisions. It is based on the idea that they should always choose the alternative with the highest expected value. Each alternative can lead to various possible outcomes, each of which has a different value. The expected value of an alternative consists in the sum of the values of each outcome associated with it multiplied by
44954-550: The motives of others without rational basis. Psychotic disorders are among the most severe mental illnesses and involve a distorted relation to reality in the form of hallucinations and delusions , as seen in schizophrenia . Other disorders include dissociative disorders and eating disorders . The biopsychosocial model identifies three types of causes of mental disorders: biological, cognitive, and environmental factors. Biological factors include bodily causes, in particular neurological influences and genetic predispositions. On
45201-405: The nature of the soul. Kabbalah separates the soul into five elements, corresponding to the five worlds : Kabbalah proposed a concept of reincarnation, the gilgul ( nefesh habehamit – the "animal soul"). Some Jewish traditions assert that the soul is housed in the luz bone, though traditions disagree as to whether it is the atlas at the top of the spine, or the sacrum at bottom of
45448-430: The need for special sciences like psychology. For example, behaviorists aim to analyze mental concepts in terms of observable behavior without resorting to internal mental states. Type identity theory also belongs to reductive physicalism and says that mental states are the same as brain states. While non-reductive physicalists agree that everything is physical, they say that mental concepts describe physical reality on
45695-404: The norm of how it should work while usually causing some form of distress . The content of those norms is controversial and there are differences from culture to culture; for example, homosexuality was historically considered a mental disorder by medical professionals, a view which only changed in the second half of 20th century. There is a great variety of mental disorders, each associated with
45942-527: The object is presented through sensory contents. Empty intentions , on the other hand, present their object in a more abstract manner without the help of sensory contents. So when perceiving a sunset, it is presented through sensory contents. The same sunset can also be presented non-intuitively when merely thinking about it without the help of sensory contents. In these cases, the same properties are ascribed to objects. The difference between these modes of presentation concerns not what properties are ascribed to
46189-407: The one hand, divergent thinking aims at coming up with as many alternative solutions as possible. On the other hand, convergent thinking tries to narrow down the range of alternatives to the most promising candidates. Some researchers identify various steps in the process of problem solving. These steps include recognizing the problem, trying to understand its nature, identifying general criteria
46436-458: The other hand, is the process of drawing conclusions from premises or evidence. Both judging and reasoning depend on the possession of the relevant concepts, which are acquired in the process of concept formation . In the case of problem solving , thinking aims at reaching a predefined goal by overcoming certain obstacles. Deliberation is an important form of practical thought that consists in formulating possible courses of action and assessing
46683-406: The other side of the spectrum are views that deny the existence of mentality in most or all non-human animals based on the idea that they lack key mental capacities, like abstract rationality and symbolic language. The status of animal minds is highly relevant to the field of ethics since it affects the treatment of animals, including the topic of animal rights . Discontinuity views state that
46930-404: The other who does not. The idea behind this example is that both listeners hear the same sounds and therefore have the same non-cognitive experience. In order to explain the difference, a distinctive cognitive phenomenology has to be posited: only the experience of the first person has this additional cognitive character since it is accompanied by a thought that corresponds to the meaning of what
47177-434: The other. In this sense, the history of an organism's experience determines which thoughts the organism has and how these thoughts unfold. But such an association does not guarantee that the connection is meaningful or rational. For example, because of the association between the terms "cold" and "Idaho", the thought "this coffee shop is cold" might lead to the thought "Russia should annex Idaho". One form of associationism
47424-557: The overall state of a person rather than specific processes, the term unconscious implies that the person lacks any awareness of their environment and themselves, like during a coma . The unconscious mind plays a central role in psychoanalysis as the part of the mind that contains thoughts, memories, and desires not accessible to conscious introspection. According to Sigmund Freud , the psychological mechanism of repression keeps disturbing phenomena, like unacceptable sexual and aggressive impulses, from entering consciousness to protect
47671-399: The past are relived. It is a form of mental time travel in which the past experience is re-experienced. But this does not constitute an exact copy of the original experience since the episodic memory involves additional aspects and information not present in the original experience. This includes both a feeling of familiarity and chronological information about the past event in relation to
47918-503: The perceiver is surprised. There is disagreement as to whether these pre-predicative aspects of regular perception should be understood as a form of cognitive phenomenology involving thinking. This issue is also important for understanding the relation between thought and language. The reason for this is that the pre-predicative expectations do not depend on language, which is sometimes taken as an example for non-linguistic thought. Various theorists have argued that pre-predicative experience
48165-580: The person tries to alleviate by following compulsive rituals . Mood disorders cause intensive moods or mood swings that are inconsistent with the external circumstances and can last for extensive periods. For instance, people affected by bipolar disorder experience extreme mood swings between manic states of euphoria and depressive states of hopelessness. Personality disorders are characterized by enduring patterns of maladaptive behavior that significantly impair regular life, like paranoid personality disorder , which leads people to be deeply suspicious of
48412-686: The physical body. Similarly, the spiritual teacher Meher Baba held that "Atman, or the soul, is in reality identical with Paramatma the Oversoul – which is one, infinite, and eternal ... [and] [t]he sole purpose of creation is for the soul to enjoy the infinite state of the Oversoul consciously." Eckankar , founded by Paul Twitchell in 1965, defines Soul as the true self; the inner, most sacred part of each person. George Gurdjieff taught that humans are not born with immortal souls but could develop them through certain efforts. Greek philosophers, such as Socrates , Plato , and Aristotle , understood that
48659-414: The pie is tasty does not automatically lead to eating the pie, since various other mental states may still inhibit this behavior, for example, the belief that it would be impolite to do so or that the pie is poisoned. Computationalist theories of thinking, often found in the cognitive sciences, understand thinking as a form of information processing. These views developed with the rise of computers in
48906-399: The premises to the thought of the conclusion. Various laws of association have been suggested. According to the laws of similarity and contrast, ideas tend to evoke other ideas that are either very similar to them or their opposite. The law of contiguity, on the other hand, states that if two ideas were frequently experienced together, then the experience of one tends to cause the experience of
49153-517: The preoperational stage until seven years, children learn to interpret and use symbols in an intuitive manner. They start employing logical reasoning to physical objects in the concrete operational stage until eleven years and extend this capacity in the following formal operational stage to abstract ideas as well as probabilities and possibilities. Other important processes shaping the mind in this period are socialization and enculturation , at first through primary caretakers and later through peers and
49400-532: The present. Memory aims at representing how things actually were in the past, in contrast to imagination, which presents objects without aiming to show how things actually are or were. Because of this missing link to actuality, more freedom is involved in most forms of imagination: its contents can be freely varied, changed, and recombined to create new arrangements never experienced before. Episodic memory and imagination have in common with other forms of thought that they can arise internally without any stimulation of
49647-435: The present. When a person remembers what they had for dinner yesterday, they employ episodic memory. Semantic memory handles general knowledge about the world that is not tied to any specific episodes. When a person recalls that the capital of Japan is Tokyo, they usually access this general information without recalling the specific instance when they learned it. Procedural memory is memory of how to do things, such as riding
49894-424: The presented object but how the object is presented. Because of this commonality, it is possible for representations belonging to different modes to overlap or to diverge. For example, when searching one's glasses one may think to oneself that one left them on the kitchen table. This empty intention of the glasses lying on the kitchen table are then intuitively fulfilled when one sees them lying there upon arriving in
50141-465: The probability that this outcome occurs. According to decision theory, a decision is rational if the agent chooses the alternative associated with the highest expected value, as assessed from the agent's own perspective. Various theorists emphasize the practical nature of thought, i.e. that thinking is usually guided by some kind of task it aims to solve. In this sense, thinking has been compared to trial-and-error seen in animal behavior when faced with
50388-601: The problem and work with more complex representations whereas novices tend to devote more time to executing putative solutions. Deliberation is an important form of practical thinking. It aims at formulating possible courses of action and assessing their value by considering the reasons for and against them. This involves foresight to anticipate what might happen. Based on this foresight, different courses of action can be formulated in order to influence what will happen. Decisions are an important part of deliberation. They are about comparing alternative courses of action and choosing
50635-456: The process of aging. Some people are affected by mental disorders , for which certain mental capacities do not function as they should. It is widely accepted that non-human animals have some form of mind, but it is controversial to which animals this applies. The topic of artificial minds poses similar challenges, with theorists discussing the possibility and consequences of creating them using computers. The main fields of inquiry studying
50882-612: The question of how thinking can fit into the material world as described by the natural sciences . Cognitive psychology aims to understand thought as a form of information processing. Developmental psychology , on the other hand, investigates the development of thought from birth to maturity and asks which factors this development depends on. Psychoanalysis emphasizes the role of the unconscious in mental life. Other fields concerned with thought include linguistics , neuroscience , artificial intelligence , biology , and sociology . Various concepts and theories are closely related to
51129-491: The reasons for and against them. This may lead to a decision by choosing the most favorable option. Both episodic memory and imagination present objects and situations internally, in an attempt to accurately reproduce what was previously experienced or as a free rearrangement, respectively. Unconscious thought is thought that happens without being directly experienced. It is sometimes posited to explain how difficult problems are solved in cases where no conscious thought
51376-519: The relation between language and thought. One prominent version in contemporary philosophy is called the language of thought hypothesis . It states that thinking happens in the medium of a mental language. This language, often referred to as Mentalese , is similar to regular languages in various respects: it is composed of words that are connected to each other in syntactic ways to form sentences. This claim does not merely rest on an intuitive analogy between language and thought. Instead, it provides
51623-587: The relation between matter and mind. The dominant position today is physicalism , which says that everything is material, meaning that minds are certain aspects or features of some material objects. The evolutionary history of the mind is tied to the development of the nervous system , which led to the formation of brains. As brains became more complex, the number and capacity of mental functions increased with particular brain areas dedicated to specific mental functions. Individual human minds also develop as they learn from experience and pass through psychological stages in
51870-454: The relation between mind and matter uses empirical observation to study how the brain works and which brain areas and processes are associated with specific mental phenomena. The brain is the central organ of the nervous system and is present in all vertebrates and the majority of invertebrates . The human brain is of particular complexity and consists of about 86 billion neurons , which communicate with one another via synapses . They form
52117-401: The representation of objects without any propositions, as when someone is thinking about their grandmother. Reasoning is one of the most paradigmatic forms of thinking. It is the process of drawing conclusions from premises or evidence. Types of reasoning can be divided into deductive and non-deductive reasoning. Deductive reasoning is governed by certain rules of inference , which guarantee
52364-479: The researcher but merely inferred from the subject's intelligent behavior. This remains true to the general behaviorist principle that behavioral evidence is required for any psychological hypothesis. One problem for behaviorism is that the same entity often behaves differently despite being in the same situation as before. This problem consists in the fact that individual thoughts or mental states usually do not correspond to one particular behavior. So thinking that
52611-509: The same individual. Monist views, by contrast, state that reality is made up of only one kind. According to idealists , everything is mental. They understand material things as mental constructs, for example, as ideas or perceptions. According to neutral monists , the world is at its most fundamental level neither physical nor mental but neutral. They see physical and mental concepts as convenient but superficial ways to describe reality. The monist view most influential in contemporary philosophy
52858-417: The same time seeking closeness and conformity with friends and peers. Further developments in this period include improvements to the reasoning ability and the formation of a principled moral viewpoint. The mind also changes during adulthood but in a less rapid and pronounced manner. Reasoning and problem-solving skills improve during early and middle adulthood. Some people experience the mid-life transition as
53105-424: The same way by many different systems, including humans, animals, and even robots. According to one such view, whether something is a thought only depends on its role "in producing further internal states and verbal outputs". Representationalism, on the other hand, focuses on the representational features of mental states and defines thoughts as sequences of intentional mental states. In this sense, computationalism
53352-458: The same. Some religions understand the soul as an independent entity that constitutes the immaterial essence of human beings, is of divine origin, survives bodily death, and is immortal . The word spirit has various additional meanings not directly associated with mind, such as a vital principle animating living beings or a supernatural being inhabiting objects or places. Cognition encompasses certain types of mental processes in which knowledge
53599-405: The schooling system. Psychological changes during adolescence are provoked both by physiological changes and being confronted with a different social situation and new expectations from others. An important factor in this period is change to the self-concept , which can take the form of an identity crisis . This process often involves developing individuality and independence from parents while at
53846-466: The seat of consciousness, emotions, thoughts, and sense of personal identity. Various fields of inquiry study the mind; the main ones include psychology , cognitive science , neuroscience , and philosophy . The words psyche and mentality are usually used as synonyms of mind . They are often employed in overlapping ways with the terms soul , spirit , cognition , intellect , intelligence , and brain but their meanings are not exactly
54093-408: The second part of the 20th century, when various theorists saw thinking in analogy to computer operations. On such views, the information may be encoded differently in the brain, but in principle, the same operations take place there as well, corresponding to the storage, transmission, and processing of information. But while this analogy has some intuitive attraction, theorists have struggled to give
54340-413: The sensory organs. But they are still closer to sensation than more abstract forms of thought since they present sensory contents that could, at least in principle, also be perceived. Conscious thought is the paradigmatic form of thinking and is often the focus of the corresponding research. But it has been argued that some forms of thought also happen on the unconscious level . Unconscious thought
54587-417: The sentence but cannot entertain the corresponding proposition. Concept formation is a form of thinking in which new concepts are acquired. It involves becoming familiar with the characteristic features shared by all instances of the corresponding type of entity and developing the ability to identify positive and negative cases. This process usually corresponds to learning the meaning of the word associated with
54834-434: The sick, one must "return" the "free soul" (which may have been stolen by an evil spirit or got lost in the spirit world) into the body. If the "free soul" can not be returned, the afflicted person dies or goes permanently insane. The shaman heals within the spiritual dimension by returning 'lost' parts of the human soul from wherever they have gone. The shaman also cleanses excess negative energies, which confuse or pollute
55081-404: The solution should meet, deciding how these criteria should be prioritized, monitoring the progress, and evaluating the results. An important distinction concerns the type of problem that is faced. For well-structured problems , it is easy to determine which steps need to be taken to solve them, but executing these steps may still be difficult. For ill-structured problems, on the other hand, it
55328-436: The soul (ψυχή, psykhḗ ) must have a logical faculty, the exercise of which was the most divine of human actions. At his defense trial, Socrates even summarized his teachings as nothing other than an exhortation for his fellow Athenians to excel in matters of the psyche since all bodily goods are dependent on such excellence ( Apology 30a–b). Aristotle reasoned that a man's body and soul were his matter and form respectively:
55575-553: The soul after death. Many within these religions and philosophies see the soul as immaterial, while others consider it possibly material. According to Chinese traditions, every person has two types of soul called hun and po ( Chinese : 魂and 魄 ; pinyin : Hún and Pò ), which are respectively yang and yin . Taoism believes in Ten souls, Sanhunqipo ( Chinese : 三魂七魄 ; pinyin : Sān hún qī pò ) ( 三魂七魄 ) "three hun and seven po ". A living being that loses any of them
55822-619: The soul is "thetan", derived from the Greek word theta , symbolizing thought. Scientologists practice a form of counselling (called auditing ) which aims to address the soul to improve abilities, both worldly and spiritual. Soul dualism, also called "multiple souls" or "dualistic pluralism", is a common belief in Shamanism , and is essential in the universal and central concept of "soul flight" (also called "soul journey", " out-of-body experience ", " ecstasy ", or " astral projection "). It
56069-446: The soul is that which moves things (i.e., that which gives life, on the view that life is self-motion) by means of its thoughts, requiring that it be both a mover and a thinker. Drawing on the words of his teacher Socrates, Plato considered the psyche to be the essence of a person, being that which decides how humans behave. He considered this essence to be an incorporeal, eternal occupant of our being. Plato said that even after death,
56316-399: The soul is the field of our psychological activity (thinking, emotions, memory, desires, will, and so on) as well as of the paranormal or psychic phenomena, such as extrasensory perception or out-of-body experiences; however, the soul is not the highest, but a middle dimension of human beings. Higher than the soul is the spirit, which is considered to be the real self; the source of everything
56563-555: The soul or spirit. In Judaism , there was originally little to no concept of a soul. As seen in the Genesis , the divine breath simply animated bodies. Then Yahweh God formed man of dust from the ground and breathed into his nostrils the breath of life; and so the man became a living being. Judaism relates the quality of one's soul to one's performance of the commandments ( mitzvot ) and reaching higher levels of understanding, and thus closeness to God. A person with such closeness
56810-529: The soul, Virchand Gandhi said that "the soul lives its own life, not for the purpose of the body, but the body lives for the purpose of the soul. If we believe that the soul is to be controlled by the body then soul misses its power." The Hebrew terms נפש nefesh (literally "living being"), רוח ruach (literally "wind"), נשמה neshamah (literally "breath"), חיה chayah (literally "life") and יחידה yechidah (literally "singularity") are used to describe
57057-457: The soul. In some ethnic groups, there can also be more than two souls. Like among the Tagbanwa people , where a person is said to have six souls – the "free soul" (which is regarded as the "true" soul) and five secondary souls with various functions. Several Inuit groups believe that a person has more than one type of soul. One is associated with respiration, the other can accompany the body as
57304-565: The souls and bodies of the unrighteous will be destroyed in Hell rather than suffering eternally ( annihilationism ). Believers will inherit eternal life either in Heaven, or in a Kingdom of God on earth, and enjoy eternal fellowship with God. Other Christians reject the punishment of the soul. Paul the Apostle used psychē ( ψυχή ) and pneuma ( πνεῦμα ) specifically to distinguish between
57551-403: The souls at the time of their death, and those that do not die [He takes] during their sleep. Then He keeps those for which He has decreed death and releases the others for a specified term. Indeed in that are signs for a people who give thought.. In Jainism, every living being, from plant or bacterium to human, has a soul and the concept forms the very basis of Jainism. According to Jainism, there
57798-509: The souls themselves ( Atman and jiva ) and have their physical representative (the body) in the world. The actual self is the soul, while the body is only a mechanism to experience the karma of that life. Thus, if one sees a tiger then there is a self-conscious identity residing in it (the soul), and a physical representative (the whole body of the tiger, which is observable) in the world. Many people believe that non-biological things, such as rivers and mountains, also possess souls. This belief
58045-448: The spine. The Scientology view is that a person does not have a soul, it is a soul. It is the belief of the religion that they do not have the power to force adherents' conclusions. Therefore, a person is immortal, and may be reincarnated if they wish. Scientologists view that one's future happiness and immortality, as guided by their spirituality, is influenced by how they live and act during their time on earth. Scientology's term for
58292-454: The term " ensouled " to represent the concept of being alive, indicating that the earliest surviving Western philosophical view believed that the soul was that which gave the body life. The soul was considered the incorporeal or spiritual "breath" that animates (from the Latin anima , cf. "animal") the living organism. Francis M. Cornford quotes Pindar by saying that the soul sleeps while
58539-473: The term "mind". This usage is encountered, for example, in the Cartesian tradition , where minds are understood as thinking things, and in the cognitive sciences . But this sense may include the restriction that such processes have to lead to intelligent behavior to be considered thought. A contrast sometimes found in the academic literature is that between thinking and feeling . In this context, thinking
58786-509: The topic of thought. The term " law of thought " refers to three fundamental laws of logic: the law of contradiction, the law of excluded middle, and the principle of identity. Counterfactual thinking involves mental representations of non-actual situations and events in which the thinker tries to assess what would be the case if things had been different. Thought experiments often employ counterfactual thinking in order to illustrate theories or to test their plausibility. Critical thinking
59033-401: The truth of the conclusion if the premises are true. For example, given the premises "all men are mortal" and "Socrates is a man", it follows deductively that "Socrates is mortal". Non-deductive reasoning, also referred to as defeasible reasoning or non-monotonic reasoning , is still rationally compelling but the truth of the conclusion is not ensured by the truth of the premises.
