91-399: Based on the by then antiquated principle of maintaining harmony between the microcosm and macrocosm , Paracelsianism fell rapidly into decline in the later 17th century with the rise of the scientific movement, but left its mark on medical practices. It was responsible for the widespread introduction of mineral therapies and several other iatrochemical techniques. Spagyric , or spagyria ,

182-454: A certain sense common, but, as a general rule, private; for, when everyone has a distinct interest, men will not complain of one another, and they will make more progress because everyone will be attending to his own business... And further, there is the greatest pleasure in doing a kindness or service to friends or guests or companions, which can only be rendered when a man has private property. These advantages are lost by excessive unification of

273-518: A city is likely impossible, however, generally assuming that philosophers would refuse to rule and the people would refuse to compel them to do so. Whereas the Republic is premised on a distinction between the sort of knowledge possessed by the philosopher and that possessed by the king or political man, Socrates explores only the character of the philosopher; in the Statesman , on the other hand,

364-570: A firm conclusion, or aporetically , has stimulated debate over the meaning of the Socratic method . Socrates is said to have pursued this probing question-and-answer style of examination on a number of topics, usually attempting to arrive at a defensible and attractive definition of a virtue . While Socrates' recorded conversations rarely provide a definite answer to the question under examination, several maxims or paradoxes for which he has become known recur. Socrates taught that no one desires what

455-430: A historical view which posited a structural similarity between the human being (the microcosm , i.e., the small order or the small universe ) and the cosmos as a whole (the macrocosm , i.e., the great order or the great universe ). Given this fundamental analogy, truths about the nature of the cosmos as a whole may be inferred from truths about human nature, and vice versa. One important corollary of this view

546-491: A hot thing cold). Therefore, they cannot truly be opposites but rather must both be manifestations of some underlying unity that is neither. This underlying unity (substratum, arche ) could not be any of the classical elements, since they were one extreme or another. For example, water is wet, the opposite of dry, while fire is dry, the opposite of wet. This initial state is ageless and imperishable, and everything returns to it according to necessity. Anaximenes in turn held that

637-466: A participant referred to as the Eleatic Stranger discusses the sort of knowledge possessed by the political man, while Socrates listens quietly. Although rule by a wise man would be preferable to rule by law, the wise cannot help but be judged by the unwise, and so in practice, rule by law is deemed necessary. Both the Republic and the Statesman reveal the limitations of politics, raising

728-460: A precursor to Epicurus ' total break between science and religion. Pythagoras lived at approximately the same time that Xenophanes did and, in contrast to the latter, the school that he founded sought to reconcile religious belief and reason. Little is known about his life with any reliability, however, and no writings of his survive, so it is possible that he was simply a mystic whose successors introduced rationalism into Pythagoreanism, that he

819-519: A single good , which was apparently combined with the Eleatic doctrine of Unity . Their work on modal logic , logical conditionals , and propositional logic played an important role in the development of logic in antiquity, and were influences on the subsequent creation of Stoicism and Pyrrhonism . During the Hellenistic and Roman periods, many different schools of thought developed in

910-499: A transcendental mathematical relation. Heraclitus must have lived after Xenophanes and Pythagoras, as he condemns them along with Homer as proving that much learning cannot teach a man to think; since Parmenides refers to him in the past tense, this would place him in the 5th century BC. Contrary to the Milesian school , which posits one stable element as the arche , Heraclitus taught that panta rhei ("everything flows"),

1001-584: A treatise called Microcosmus ), by the Andalusian mystic Ibn Arabi (1165–1240), by the German cardinal Nicholas of Cusa (1401–1464), and by numerous others. The revival of Hermeticism and Neoplatonism in the Renaissance , both of which had reserved a prominent place for the microcosm–macrocosm analogy, also led to a marked rise in popularity of the latter. Some of the most notable proponents of

1092-512: A wide variety of subjects, including astronomy , epistemology , mathematics , political philosophy , ethics , metaphysics , ontology , logic , biology , rhetoric and aesthetics . Greek philosophy continued throughout the Hellenistic period and later evolved into Roman philosophy . Greek philosophy has influenced much of Western culture since its inception, and can be found in many aspects of public education. Alfred North Whitehead once claimed: "The safest general characterization of

1183-409: Is a method developed by Paracelsus and his followers which was thought to improve the efficacy of existing medicines by separating them into their primordial elements (the tria prima : sulphur, mercury, and salt) and then again recombining them. Paracelsian physicians held that through this method the medically beneficial ingredients of a compound (the purified tria prima ) were separated from

1274-582: Is a story that Protagoras , too, was forced to flee and that the Athenians burned his books. Socrates, however, is the only subject recorded as charged under this law, convicted, and sentenced to death in 399 BC (see Trial of Socrates ). In the version of his defense speech presented by Plato, he claims that it is the envy he arouses on account of his being a philosopher that will convict him. Numerous subsequent philosophical movements were inspired by Socrates or his younger associates. Plato casts Socrates as

1365-470: Is ancient, and may be found in many philosophical systems world-wide, such as for example in ancient Mesopotamia , in ancient Iran , or in ancient Chinese philosophy . However, the terms microcosm and macrocosm refer more specifically to the analogy as it was developed in ancient Greek philosophy and its medieval and early modern descendants. In contemporary usage, the terms microcosm and macrocosm are also employed to refer to any smaller system that

1456-538: Is bad, and so if anyone does something that truly is bad, it must be unwillingly or out of ignorance; consequently, all virtue is knowledge. He frequently remarks on his own ignorance (claiming that he does not know what courage is, for example). Plato presents him as distinguishing himself from the common run of mankind by the fact that, while they know nothing noble and good, they do not know that they do not know, whereas Socrates knows and acknowledges that he knows nothing noble and good. The great statesman Pericles

1547-577: Is derived from the Republic , the Laws , and the Statesman . The first of these contains the suggestion that there will not be justice in cities unless they are ruled by philosopher kings ; those responsible for enforcing the laws are compelled to hold their women, children, and property in common ; and the individual is taught to pursue the common good through noble lies ; the Republic says that such

1638-409: Is no coming into being or passing away, genesis or decay, they said that things appear to come into being and pass away because the elements out of which they are composed assemble or disassemble while themselves being unchanging. Leucippus also proposed an ontological pluralism with a cosmogony based on two main elements: the vacuum and atoms. These, by means of their inherent movement, are crossing

1729-523: Is not always easy to distinguish between the two. While the Socrates presented in the dialogues is often taken to be Plato's mouthpiece, Socrates' reputation for irony , his caginess regarding his own opinions in the dialogues, and his occasional absence from or minor role in the conversation serve to conceal Plato's doctrines. Much of what is said about his doctrines is derived from what Aristotle reports about them. The political doctrine ascribed to Plato

1820-548: Is representative of a larger one, and vice versa. Among ancient Greek and Hellenistic philosophers, notable proponents of the microcosm–macrocosm analogy included Anaximander ( c.  610  – c.  546 BCE ), Plato ( c.  428 or 424  – c.  348 BCE ), the Hippocratic authors (late 5th or early 4th century BCE and onwards), and the Stoics (3rd century BCE and onwards). In later periods,

1911-458: Is that the cosmos as a whole may be considered to be alive, and thus to have a mind or soul (the world soul ), a position advanced by Plato in his Timaeus . Moreover, this cosmic mind or soul was often thought to be divine, most notably by the Stoics and those who were influenced by them, such as the authors of the Hermetica . Hence, it was sometimes inferred that the human mind or soul

2002-405: Is the arche of everything. Pythagoreanism also incorporated ascetic ideals, emphasizing purgation, metempsychosis , and consequently a respect for all animal life; much was made of the correspondence between mathematics and the cosmos in a musical harmony. Pythagoras believed that behind the appearance of things, there was the permanent principle of mathematics, and that the forms were based on

2093-571: The Bundahishn , a Zoroastrian encyclopedic work, and the Avot de-Rabbi Nathan , a Jewish Rabbinical text . Medieval philosophy was generally dominated by Aristotle , who – despite having been the first to coin the term "microcosm" – had posited a fundamental and insurmountable difference between the region below the Moon (the sublunary world , consisting of the four elements ) and

2184-592: The φύσις of all things." Xenophanes was born in Ionia , where the Milesian school was at its most powerful and may have picked up some of the Milesians' cosmological theories as a result. What is known is that he argued that each of the phenomena had a natural rather than divine explanation in a manner reminiscent of Anaximander's theories and that there was only one god, the world as a whole, and that he ridiculed

2275-615: The European philosophical tradition is that it consists of a series of footnotes to Plato". Clear, unbroken lines of influence lead from ancient Greek and Hellenistic philosophers to Roman philosophy , Early Islamic philosophy , Medieval Scholasticism , the European Renaissance and the Age of Enlightenment . Greek philosophy was influenced to some extent by the older wisdom literature and mythological cosmogonies of

2366-569: The Hellenistic world and then the Greco-Roman world. The spread of Christianity throughout the Roman world, followed by the spread of Islam , ushered in the end of Hellenistic philosophy and the beginnings of Medieval philosophy , which was dominated by the three Abrahamic traditions: Jewish philosophy , Christian philosophy , and early Islamic philosophy . Pyrrho of Elis , a Democritean philosopher, traveled to India with Alexander

2457-530: The New Academy , although some ancient authors added further subdivisions, such as a Middle Academy . The Academic skeptics did not doubt the existence of truth ; they just doubted that humans had the capacities for obtaining it. They based this position on Plato's Phaedo , sections 64–67, in which Socrates discusses how knowledge is not accessible to mortals. While the objective of the Pyrrhonists

2548-591: The absence of pain in the body and trouble in the mind". The founder of Stoicism, Zeno of Citium , was taught by Crates of Thebes, and he took up the Cynic ideals of continence and self-mastery, but applied the concept of apatheia (indifference) to personal circumstances rather than social norms, and switched shameless flouting of the latter for a resolute fulfillment of social duties. Logic and physics were also part of early Stoicism, further developed by Zeno's successors Cleanthes and Chrysippus . Their metaphysics

2639-479: The ancient Near East , though the extent of this influence is widely debated. The classicist Martin Litchfield West states, "contact with oriental cosmology and theology helped to liberate the early Greek philosophers' imagination; it certainly gave them many suggestive ideas. But they taught themselves to reason. Philosophy as we understand it is a Greek creation". Subsequent philosophic tradition

2730-720: The anthropomorphism of the Greek religion by claiming that cattle would claim that the gods looked like cattle, horses like horses, and lions like lions, just as the Ethiopians claimed that the gods were snub-nosed and black and the Thracians claimed they were pale and red-haired. Xenophanes was highly influential to subsequent schools of philosophy. He was seen as the founder of a line of philosophy that culminated in Pyrrhonism , possibly an influence on Eleatic philosophy , and

2821-455: The arche was air, although John Burnet argues that by this, he meant that it was a transparent mist, the aether . Despite their varied answers, the Milesian school was searching for a natural substance that would remain unchanged despite appearing in different forms, and thus represents one of the first scientific attempts to answer the question that would lead to the development of modern atomic theory; "the Milesians," says Burnet, "asked for

2912-527: The cosmos as a whole (the macrocosm , from Koinē Greek: μακρὸς κόσμος , romanized:  makròs kósmos , lit.   'great universe'). The view was elaborated by the Jewish philosopher Philo (c. 20 BCE–50 CE), who adopted it from Hellenistic philosophy . Similar ideas can also be found in early rabbinical literature . In the Middle Ages, the analogy became a prominent theme in

3003-504: The pre-Socratics gained currency with the 1903 publication of Hermann Diels' Fragmente der Vorsokratiker , although the term did not originate with him. The term is considered useful because what came to be known as the "Athenian school" (composed of Socrates, Plato, and Aristotle ) signaled the rise of a new approach to philosophy; Friedrich Nietzsche 's thesis that this shift began with Plato rather than with Socrates (hence his nomenclature of "pre-Platonic philosophy") has not prevented

3094-426: The pyramids . Thales inspired the Milesian school of philosophy and was followed by Anaximander , who argued that the substratum or arche could not be water or any of the classical elements but was instead something "unlimited" or "indefinite" (in Greek, the apeiron ). He began from the observation that the world seems to consist of opposites (e.g., hot and cold), yet a thing can become its opposite (e.g.,

3185-555: The regimes described in Plato's Republic and Laws , and refers to the theory of forms as "empty words and poetic metaphors". He is generally presented as giving greater weight to empirical observation and practical concerns. Aristotle's fame was not great during the Hellenistic period , when Stoic logic was in vogue, but later peripatetic commentators popularized his work, which eventually contributed heavily to Islamic, Jewish, and medieval Christian philosophy. His influence

3276-563: The sage and the fool. Slight as the difference may appear between the positions of the Academic skeptics and the Pyrrhonists, a comparison of their lives leads to the conclusion that a practical philosophical moderation was the characteristic of the Academic skeptics whereas the objectives of the Pyrrhonists were more psychological. Following the end of the skeptical period of the Academy with Antiochus of Ascalon , Platonic thought entered

3367-460: The Great 's army where Pyrrho was influenced by Buddhist teachings, most particularly the three marks of existence . After returning to Greece, Pyrrho started a new school of philosophy, Pyrrhonism , which taught that it is one's opinions about non-evident matters (i.e., dogma ) that prevent one from attaining eudaimonia . Pyrrhonism places the attainment of ataraxia (a state of equanimity ) as

At least twenty-nine of his treatises have survived, known as the corpus Aristotelicum , and address a variety of subjects including logic , physics , optics , metaphysics , ethics , rhetoric , politics , poetry , botany, and zoology. Aristotle is often portrayed as disagreeing with his teacher Plato (e.g., in Raphael 's School of Athens ). He criticizes

3549-400: The Milesian school, in suggesting that the substratum could appear in a variety of different guises, implied that everything that exists is corpuscular, Parmenides argued that the first principle of being was One, indivisible, and unchanging. Being, he argued, by definition implies eternality, while only that which is can be thought; a thing which is , moreover, cannot be more or less, and so

3640-530: The analogy in the rabbinical work Avot de-Rabbi Natan had still been relatively simple and crude, much more elaborate versions of this application were given by Bahya ibn Paquda and Joseph ibn Tzaddik (in his Sefer ha-Olam ha-Katan , "Book of the Microcosm"), both of whom compared human parts with the heavenly bodies and other parts of the cosmos at large. The analogy was linked to the ancient theme of " know thyself " (Greek: γνῶθι σεαυτόν, gnōthi seauton ) by

3731-531: The analogy was already in use by earlier Jewish philosophers. In his commentary on the Sefer Yetzirah ("Book of Creation"), Saadia Gaon (882/892–942) put forward a set of analogies between the cosmos, the Tabernacle , and the human being. Saadia was followed in this by a number of later authors, such as Bahya ibn Paquda, Judah Halevi, and Abraham ibn Ezra. Whereas the physiological application of

3822-504: The analogy was especially prominent in the works of those philosophers who were heavily influenced by Platonic and Stoic thought, such as Philo of Alexandria ( c.  20 BCE  – c.  50 CE ), the authors of the early Greek Hermetica ( c.  100 BCE–300 CE ), and the Neoplatonists (3rd century CE and onwards). The analogy was also employed in late antique and early medieval religious literature, such as in

3913-581: The choice of "Early Greek Philosophy" over "pre-Socratic philosophy" most notably because Socrates is contemporary and sometimes even prior to philosophers traditionally considered "pre-Socratic" (e.g., the Atomists). The early Greek philosophers (or "pre-Socratics") were primarily concerned with cosmology , ontology , and mathematics. They were distinguished from "non-philosophers" insofar as they rejected mythological explanations in favor of reasoned discourse. Thales of Miletus , regarded by Aristotle as

4004-461: The closest element to this eternal flux being fire. All things come to pass in accordance with Logos , which must be considered as "plan" or "formula", and "the Logos is common". He also posited a unity of opposites , expressed through dialectic , which structured this flux, such as that seeming opposites in fact are manifestations of a common substrate to good and evil itself. Heraclitus called

4095-515: The concept in this period include Marsilio Ficino (1433 – 1499), Heinrich Cornelius Agrippa (1486–1535), Francesco Patrizi (1529–1597), Giordano Bruno (1548–1600), and Tommaso Campanella (1568–1639). It was also central to the new medical theories propounded by the Swiss physician Paracelsus (1494–1541) and his many followers , most notably Robert Fludd (1574–1637). Andreas Vesalius (1514–1564) in his anatomy text De fabrica wrote that

4186-445: The conclusion being that one cannot look to nature for guidance regarding how to live one's life. Protagoras and subsequent sophists tended to teach rhetoric as their primary vocation. Prodicus , Gorgias , Hippias , and Thrasymachus appear in various dialogues , sometimes explicitly teaching that while nature provides no ethical guidance, the guidance that the laws provide is worthless, or that nature favors those who act against

4277-607: The difference between the changing, perceptible world and the unchanging, intelligible realm. Platonism stands in opposition to nominalism , which denies the existence of such abstract entities. Around 266 BC, Arcesilaus became head of the Platonic Academy , and adopted skepticism as a central tenet of Platonism , making Platonism nearly the same as Pyrrhonism . After Arcesilaus, Academic skepticism diverged from Pyrrhonism. This skeptical period of ancient Platonism, from Arcesilaus to Philo of Larissa , became known as

4368-585: The ethics of Cynicism to articulate Stoicism . Epicurus studied with Platonic and Pyrrhonist teachers before renouncing all previous philosophers (including Democritus , on whose atomism the Epicurean philosophy relies). The philosophic movements that were to dominate the intellectual life of the Roman Empire were thus born in this febrile period following Socrates' activity, and either directly or indirectly influenced by him. They were also absorbed by

4459-550: The expanding Muslim world in the 7th through 10th centuries AD, from which they returned to the West as foundations of Medieval philosophy and the Renaissance , as discussed below. Plato was an Athenian of the generation after Socrates . Ancient tradition ascribes thirty-six dialogues and thirteen letters to him, although of these only twenty-four of the dialogues are now universally recognized as authentic; most modern scholars believe that at least twenty-eight dialogues and two of

4550-459: The first philosopher, held that all things arise from a single material substance, water. It is not because he gave a cosmogony that John Burnet calls him the "first man of science", but because he gave a naturalistic explanation of the cosmos and supported it with reasons. According to tradition, Thales was able to predict an eclipse and taught the Egyptians how to measure the height of

4641-512: The freedom from fears and desires was happiness itself. Platonism is the philosophy of Plato , asserting the existence of abstract objects , which exist in a realm distinct from both the physical world and the mind. Central to Platonism is the Theory of Forms , where ideal Forms or perfect archetypes are considered the true reality, with the physical world being an imperfect reflection. This philosophy has influenced Western thought , emphasizing

4732-430: The harmful and toxic ones, turning even some poisons into medicines. This procedure involved fermentation , distillation , and extraction of mineral components from the ash of the plant . These processes were in use in medieval alchemy generally for the separation and purification of metals from ores (see Calcination ), and salts from brines and other aqueous solutions . Originally coined by Paracelsus,

4823-429: The heavens, placed it in cities, introduced it into families, and obliged it to examine into life and morals, and good and evil." By this account he would be considered the founder of political philosophy . The reasons for this turn toward political and ethical subjects remain the object of much study. The fact that many conversations involving Socrates (as recounted by Plato and Xenophon ) end without having reached

4914-529: The human body "in many respects corresponds admirably to the universe and for that reason was called the little universe by the ancients." Analogies between microcosm and macrocosm are found throughout the history of Jewish philosophy . According to this analogy, there is a structural similarity between the human being (the microcosm , from Koinē Greek : μικρὸς κόσμος , romanized:  mikròs kósmos , Hebrew : עולם קטן , romanized :  ʻolam qāṭān , lit.   'small universe') and

5005-466: The laws. Socrates , believed to have been born in Athens in the 5th century BC , marks a watershed in ancient Greek philosophy. Athens was a center of learning, with sophists and philosophers traveling from across Greece to teach rhetoric, astronomy, cosmology, and geometry. While philosophy was an established pursuit prior to Socrates, Cicero credits him as "the first who brought philosophy down from

5096-471: The letters were in fact written by Plato, although all of the thirty-six dialogues have some defenders. A further nine dialogues are ascribed to Plato but were considered spurious even in antiquity. Plato's dialogues feature Socrates, although not always as the leader of the conversation. (One dialogue, the Laws , instead contains an "Athenian Stranger".) Along with Xenophon , Plato is the primary source of information about Socrates' life and beliefs and it

5187-438: The main interlocutor in his dialogues , deriving from them the basis of Platonism (and by extension, Neoplatonism ). Plato's student Aristotle in turn criticized and built upon the doctrines he ascribed to Socrates and Plato, forming the foundation of Aristotelianism . Antisthenes founded the school that would come to be known as Cynicism and accused Plato of distorting Socrates' teachings. Zeno of Citium in turn adapted

5278-798: The microcosm–macrocosm analogy were the Epistles of the Brethren of Purity , an encyclopedic work written in the 10th century by an anonymous group of Shi'i Muslim philosophers. Having been brought to al-Andalus at an early date by the hadith scholar and alchemist Maslama al-Majriti of the Umayyad state of Córdoba (died 964), the Epistles were of central importance to Sephardic philosophers such as Bahya ibn Paquda (c. 1050–1120), Judah Halevi (c. 1075–1141), Joseph ibn Tzaddik (died 1149), and Abraham ibn Ezra (c. 1090–1165). Nevertheless,

5369-507: The most famous is perhaps the Allegory of the Cave . It likens most humans to people tied up in a cave, who look only at shadows on the walls and have no other conception of reality. If they turned around, they would see what is casting the shadows (and thereby gain a further dimension to their reality). If some left the cave, they would see the outside world illuminated by the sun (representing

5460-552: The most famous of which is his theory of forms . It holds that non-material abstract (but substantial ) forms (or ideas), and not the material world of change known to us through our physical senses, possess the highest and most fundamental kind of reality. He argued extensively in the Phaedo , Phaedrus , and Republic for the immortality of the soul, and he believed specifically in reincarnation . Plato often uses long-form analogies (usually allegories ) to explain his ideas;

5551-419: The most influential philosophers of all time, stressed the implication that understanding relies upon first-hand observation. Aristotle moved to Athens from his native Stageira in 367 BC and began to study philosophy (perhaps even rhetoric, under Isocrates ), eventually enrolling at Plato's Academy . He left Athens approximately twenty years later to study botany and zoology , became a tutor of Alexander

5733-477: The only human good, but he had also accepted a limited role for its utilitarian side, allowing pleasure to be a secondary goal of moral action. Aristippus and his followers seized upon this, and made pleasure the sole final goal of life, denying that virtue had any intrinsic value. The Megarian school flourished in the 4th century BC. It was founded by Euclides of Megara , one of the pupils of Socrates . Its ethical teachings were derived from Socrates, recognizing

5824-412: The oppositional processes ἔρις ( eris ), "strife", and hypothesized that the apparently stable state of δίκη ( dikê ), or "justice", is the harmonic unity of these opposites. Parmenides of Elea cast his philosophy against those who held "it is and is not the same, and all things travel in opposite directions,"—presumably referring to Heraclitus and those who followed him. Whereas the doctrines of

5915-507: The period of Middle Platonism , which absorbed ideas from the Peripatetic and Stoic schools. More extreme syncretism was done by Numenius of Apamea , who combined it with Neopythagoreanism . Also affected by the neopythagoreans, the neoplatonists , first of them Plotinus , argued that mind exists before matter, and that the universe has a singular cause which must therefore be a single mind. As such, neoplatonism became essentially

6006-415: The physician and philosopher Isaac Israeli (c. 832–932), who suggested that by knowing oneself, a human being may gain knowledge of all things. This theme of self-knowledge returned in the works of Joseph ibn Tzaddik, who added that in this way humans may come to know God himself. The macrocosm was also associated with the divine by Judah Halevi, who saw God as the spirit, soul, mind, and life that animates

6097-666: The predominance of the "pre-Socratic" distinction. Since 2016, however, current scholarship has transitioned from calling philosophy before the Athenian school "pre-Socratic" to simply "Early Greek Philosophy". André Laks and Glenn W. Most have been partly responsible for popularizing this shift in describing the era preceding the Athenian School through their comprehensive, nine volume Loeb editions of Early Greek Philosophy . In their first volume, they distinguish their systematic approach from that of Hermann Diels, beginning with

6188-539: The question of what political order would be best given those constraints; that question is addressed in the Laws , a dialogue that does not take place in Athens and from which Socrates is absent. The character of the society described there is eminently conservative, a corrected or liberalized timocracy on the Spartan or Cretan model or that of pre-democratic Athens . Plato's dialogues also have metaphysical themes,

6279-580: The rarefaction and condensation of the Milesians is impossible regarding Being; lastly, as movement requires that something exist apart from the thing moving (viz. the space into which it moves), the One or Being cannot move, since this would require that "space" both exist and not exist. While this doctrine is at odds with ordinary sensory experience, where things do indeed change and move, the Eleatic school followed Parmenides in denying that sense phenomena revealed

6370-609: The region above the Moon (the superlunary world, consisting of a fifth element ). Nevertheless, the microcosm–macrocosm analogy was adopted by a wide variety of medieval thinkers working in different linguistic traditions: the concept of microcosm was known in Arabic as ʿālam ṣaghīr , in Hebrew as olam katan , and in Latin as microcosmus or minor mundus . The analogy was elaborated by alchemists such as those writing under

6461-500: The state." Cynicism was founded by Antisthenes , who was a disciple of Socrates, as well as Diogenes , his contemporary. Their aim was to live according to nature and against convention. Antisthenes was inspired by the ascetism of Socrates, and accused Plato of pride and conceit. Diogenes, his follower, took the ideas to their limit, living in extreme poverty and engaging in anti-social behaviour. Crates of Thebes was, in turn, inspired by Diogenes to give away his fortune and live on

6552-400: The streets of Athens. The Cyrenaics were founded by Aristippus of Cyrene, who was a pupil of Socrates . The Cyrenaics were hedonists and held that pleasure was the supreme good in life, especially physical pleasure, which they thought more intense and more desirable than mental pleasures. Pleasure is the only good in life and pain is the only evil. Socrates had held that virtue was

6643-450: The ultimate form of goodness and truth). If these travelers then re-entered the cave, the people inside (who are still only familiar with the shadows) would not be equipped to believe reports of this 'outside world'. This story explains the theory of forms with their different levels of reality, and advances the view that philosopher-kings are wisest while most humans are ignorant. One student of Plato, Aristotle , who would become another of

6734-434: The universe, while according to Maimonides (1138–1204), the relationship between God and the universe is analogous to the relationship between the intellect and the human being.

Philosophy was used to make sense of the world using reason. It dealt with

His theories were not well known by the time of Plato , however, and they were ultimately incorporated into the work of his student, Democritus . Sophism arose from the juxtaposition of physis (nature) and nomos (law). John Burnet posits its origin in the scientific progress of the previous centuries which suggested that Being was radically different from what

6916-578: The way to achieve eudaimonia. To bring the mind to ataraxia Pyrrhonism uses epoché ( suspension of judgment ) regarding all non-evident propositions. Pyrrhonists dispute that the dogmatists – which includes all of Pyrrhonism's rival philosophies – have found truth regarding non-evident matters. For any non-evident matter, a Pyrrhonist makes arguments for and against such that the matter cannot be concluded, thus suspending belief and thereby inducing ataraxia. Epicurus studied in Athens with Nausiphanes , who

7007-573: The word comes from the Ancient Greek σπάω spao ('to separate, to draw out') and ἀγείρω ageiro ('to combine', 'to recombine', 'to gather'). In its original use, the word spagyric was commonly used synonymously with the word alchemy , however, in more recent times it has often been adopted by alternative medicine theorists and various techniques of holistic medicine . Microcosm and macrocosm The microcosm–macrocosm analogy (or, equivalently, macrocosm–microcosm analogy ) refers to

7098-464: The works of most Jewish philosophers. In the Avot de-Rabbi Natan (compiled c. 700–900), human parts are compared with parts belonging to the larger world: the hair is like a forest, the lungs like the wind, the loins like counsellors, the stomach like a mill, etc. The microcosm–macrocosm analogy was a common theme among medieval Jewish philosophers, just as it was among the Arabic philosophers who were their peers. Especially influential concerning

7189-498: The world as it actually was; instead, the only thing with Being was thought, or the question of whether something exists or not is one of whether it can be thought. In support of this, Parmenides' pupil Zeno of Elea attempted to prove that the concept of motion was absurd and as such motion did not exist. He also attacked the subsequent development of pluralism, arguing that it was incompatible with Being. His arguments are known as Zeno's paradoxes . The power of Parmenides' logic

7280-455: Was Protagoras , whom he presents as teaching that all virtue is conventional. It was Protagoras who claimed that "man is the measure of all things, of the things that are, that they are, and of the things that are not, that they are not," which Plato interprets as a radical perspectivism , where some things seem to be one way for one person (and so actually are that way) and another way for another person (and so actually are that way as well);

7371-399: Was a follower of Democritus and a student of Pyrrho of Elis . He accepted Democritus' theory of atomism, with improvements made in response to criticisms by Aristotle and others. His ethics were based on "the pursuit of pleasure and the avoidance of pain". This was, however, not simple hedonism , as he noted that "We do not mean the pleasures of the prodigal or of sensuality . . . we mean

7462-483: Was based in materialism , which was structured by logos , reason (but also called God or fate). Their logical contributions still feature in contemporary propositional calculus . Their ethics was based on pursuing happiness, which they believed was a product of 'living in accordance with nature'. This meant accepting those things which one could not change. One could therefore choose whether to be happy or not by adjusting one's attitude towards their circumstances, as

7553-430: Was closely associated with this new learning and a friend of Anaxagoras , however, and his political opponents struck at him by taking advantage of a conservative reaction against the philosophers; it became a crime to investigate the things above the heavens or below the earth, subjects considered impious. Anaxagoras is said to have been charged and to have fled into exile when Socrates was about twenty years of age. There

7644-427: Was divine in nature as well. Apart from this important psychological and noetic (i.e., related to the mind ) application, the analogy was also applied to human physiology . For example, the cosmological functions of the seven classical planets were sometimes taken to be analogous to the physiological functions of human organs , such as the heart , the spleen , the liver , the stomach , etc. The view itself

7735-402: Was experienced by the senses and, if comprehensible at all, was not comprehensible in terms of order; the world in which people lived, on the other hand, was one of law and order, albeit of humankind's own making. At the same time, nature was constant, while what was by law differed from one place to another and could be changed. The first person to call themselves a sophist, according to Plato,

7826-449: Was kept at natural limit of consumption. 'Unnatural' trade, as opposed to the intended limit, was classified as the acquisition of wealth to attain more wealth instead of to purchase more goods. Cutting more along the grain of reality, Aristotle did not only set his mind on how to give people direction to make the right choices but wanted each person equipped with the tools to perform this moral duty. In his own words, "Property should be in

7917-548: Was simply a rationalist whose successors are responsible for the mysticism in Pythagoreanism, or that he was actually the author of the doctrine; there is no way to know for certain. Pythagoras is said to have been a disciple of Anaximander and to have imbibed the cosmological concerns of the Ionians, including the idea that the cosmos is constructed of spheres, the importance of the infinite, and that air or aether

8008-419: Was so influenced by Socrates as presented by Plato that it is conventional to refer to philosophy developed prior to Socrates as pre-Socratic philosophy . The periods following this, up to and after the wars of Alexander the Great , are those of "Classical Greek" and " Hellenistic philosophy ", respectively. The convention of terming those philosophers who were active prior to the death of Socrates as

8099-696: Was such that Avicenna referred to him simply as "the Master"; Maimonides , Alfarabi , Averroes , and Aquinas as "the Philosopher". Aristotle opposed the utopian style of theorizing, deciding to rely on the understood and observed behaviors of people in reality to formulate his theories. Stemming from an underlying moral assumption that life is valuable, the philosopher makes a point that scarce resources ought to be responsibly allocated to reduce poverty and death. This 'fear of goods' led Aristotle to exclusively support 'natural' trades in which personal satiation

8190-573: Was such that some subsequent philosophers abandoned the monism of the Milesians, Xenophanes, Heraclitus, and Parmenides, where one thing was the arche . In place of this, they adopted pluralism , such as Empedocles and Anaxagoras . There were, they said, multiple elements which were not reducible to one another and these were set in motion by love and strife (as in Empedocles) or by Mind (as in Anaxagoras). Agreeing with Parmenides that there

8281-417: Was the attainment of ataraxia , after Arcesilaus the Academic skeptics did not hold up ataraxia as the central objective. The Academic skeptics focused on criticizing the dogmas of other schools of philosophy, in particular of the dogmatism of the Stoics . They acknowledged some vestiges of a moral law within, at best but a plausible guide, the possession of which, however, formed the real distinction between
