Ancient Greek philosophy arose in the 6th century BC. Philosophy was used to make sense of the world using reason. It dealt with 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 .
117-465: In Ancient Greek philosophy , ataraxia ( Greek : ἀταραξία , from ἀ- indicating negation or absence and ταραχ- tarach- ' to disturb, trouble ' with the abstract noun suffix -ία ), generally translated as ' unperturbedness ' , ' imperturbability ' , ' equanimity ' , or ' tranquility ' , is a lucid state of robust equanimity characterized by ongoing freedom from distress and worry. In non-philosophical usage, ataraxia

Theology Theology is the study of religious belief from a religious perspective, with a focus on the nature of divinity . It is taught as an academic discipline , typically in universities and seminaries . It occupies itself with the unique content of analyzing the supernatural , but also deals with religious epistemology , asks and seeks to answer
351-454: 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
468-518: 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,
585-757: A commitment conflicts with academic freedom. In some contexts, theology has been held to belong in institutions of higher education primarily as a form of professional training for Christian ministry. This was the basis on which Friedrich Schleiermacher , a liberal theologian, argued for the inclusion of theology in the new University of Berlin in 1810. For instance, in Germany , theological faculties at state universities are typically tied to particular denominations, Protestant or Roman Catholic, and those faculties will offer denominationally-bound (konfessionsgebunden) degrees, and have denominationally bound public posts amongst their faculty; as well as contributing "to
702-570: 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
819-491: 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
936-466: 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
1053-460: 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
1170-1026: A primary purpose at their foundation. Seminaries and bible colleges have continued this alliance between the academic study of theology and training for Christian ministry. There are, for instance, numerous prominent examples in the United States, including Phoenix Seminary , Catholic Theological Union in Chicago, The Graduate Theological Union in Berkeley, Criswell College in Dallas, The Southern Baptist Theological Seminary in Louisville, Trinity Evangelical Divinity School in Deerfield, Illinois, Dallas Theological Seminary , North Texas Collegiate Institute in Farmers Branch, Texas, and
1287-746: A religious tradition; or it may be used to compare , challenge (e.g. biblical criticism ), or oppose (e.g. irreligion ) a religious tradition or worldview . Theology might also help a theologian address some present situation or need through a religious tradition, or to explore possible ways of interpreting the world. The term "theology" derives from the Greek theologia (θεολογία), a combination of theos (Θεός, ' god ') and logia (λογία, 'utterances, sayings, oracles ')—the latter word relating to Greek logos (λόγος, 'word, discourse , account, reasoning '). The term would pass on to Latin as theologia , then French as théologie , eventually becoming

During the Hellenistic and Roman periods, many different schools of thought developed in

Ataraxia , as both a mental and katastematic pleasure, is key to a person's happiness. In Stoicism, unlike Pyrrhonism or Epicureanism, ataraxia , or tranquillity of the mind, is not the ultimate goal of life. Instead, the goal is a life of virtue according to nature, which
1638-499: 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"),

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

For instance: The earliest universities were developed under the aegis of the Latin Church by papal bull as studia generalia and perhaps from cathedral schools . It is possible, however, that the development of cathedral schools into universities was quite rare, with the University of Paris being an exception. Later they were also founded by kings ( University of Naples Federico II , Charles University in Prague , Jagiellonian University in Kraków ) or by municipal administrations ( University of Cologne , University of Erfurt ). In

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
2106-448: Is constituted by a triple aspect: what is taught by God, teaches of God, and leads to God ( Latin : Theologia a Deo docetur, Deum docet, et ad Deum ducit ). This indicates the three distinct areas of God as theophanic revelation , the systematic study of the nature of divine and, more generally, of religious belief , and the spiritual path . Christian theology as the study of Christian belief and practice concentrates primarily upon

2457-541: Is in fault not religion. Theology is a science that may justly be compared to the Box of Pandora . Many good things lie uppermost in it; but many evil lie under them, and scatter plagues and desolation throughout the world."

However, since Stoics in a state of apatheia do not care about matters outside of themselves and are not susceptible to emotion, they would be unable to be disturbed by anything at all, meaning that they were also in a stage of mental tranquillity and thus in a state of ataraxia .

In some contemporary contexts, a distinction is made between theology, which is seen as involving some level of commitment to the claims of the religious tradition being studied, and religious studies , which by contrast is normally seen as requiring that the question of the truth or falsehood of the religious traditions studied be kept outside its field. Religious studies involves

Since at least the eighteenth century, various authors have criticized the suitability of theology as an academic discipline. In 1772, Baron d'Holbach labeled theology "a continual insult to human reason" in Le Bon sens . Lord Bolingbroke , an English politician and political philosopher, wrote in Section IV of his Essays on Human Knowledge , "Theology

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
3042-523: 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

Whatever the case, there are various Buddhist theories and discussions on the nature of Buddhahood and the ultimate reality / highest form of divinity , which has been termed "buddhology" by some scholars like Louis de La Vallée-Poussin . This is a different usage of the term than when it is taken to mean the academic study of Buddhism , and here would refer to

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.

Richard Hooker defines theology as "the science of things divine". The term can, however, be used for a variety of disciplines or fields of study. Theology considers whether the divine exists in some form, such as in physical , supernatural , mental , or social realities , and what evidence for and about it may be found via personal spiritual experiences or historical records of such experiences as documented by others.

In the Renaissance , especially with Florentine Platonist apologists of Dante 's poetics, the distinction between 'poetic theology' ( theologia poetica ) and 'revealed' or Biblical theology serves as stepping stone for a revival of philosophy as independent of theological authority.

It served as the capstone to the Trivium and Quadrivium that young men were expected to study. This meant that the other subjects (including philosophy ) existed primarily to help with theological thought. In this context, medieval theology in the Christian West could subsume fields of study which would later become more self-sufficient, such as metaphysics (Aristotle's " first philosophy ", or ontology (the science of being).

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.

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

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 ).

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
9009-526: The manifestations of thousands of gods and their aspects. In recent decades the study of Hinduism has also been taken up by a number of academic institutions in Europe, such as the Oxford Centre for Hindu Studies and Bhaktivedanta College . There are also other traditions of Hindu theology, including the various theologies of Shaivism (which include dualistic and non-dualistic strands) as well as
9126-507: 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
9243-552: 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;
9360-419: 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
9477-477: 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
9594-412: 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
9711-507: 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
9828-511: The physical and the mental. They consider mental, not physical, pleasures to be of high importance because physical pleasures exist only in the present; while mental pleasures exist in the past, the present, and the future. Epicureans further separate pleasure into what they call kinetic pleasure, those that come about through action or change, and katastematic pleasures, those that come about through an absence of distress. Those who achieved freedom from physical disturbance were said to be in
9945-666: 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
10062-556: The question of revelation . Revelation pertains to the acceptance of God , gods , or deities , as not only transcendent or above the natural world, but also willing and able to interact with the natural world and to reveal themselves to humankind. Theologians use various forms of analysis and argument ( experiential , philosophical , ethnographic , historical , and others) to help understand , explain , test, critique , defend or promote any myriad of religious topics . As in philosophy of ethics and case law , arguments often assume
10179-539: 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,
10296-580: 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
10413-500: 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
10530-400: 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
10647-562: The study of religions that worship a supposed deity (a theos ), i.e. more widely than monotheism ; and presuppose a belief in the ability to speak and reason about this deity (in logia ). They suggest the term is less appropriate in religious contexts that are organized differently (i.e., religions without a single deity, or that deny that such subjects can be studied logically). Hierology has been proposed, by such people as Eugène Goblet d'Alviella (1908), as an alternative, more generic term. As defined by Thomas Aquinas , theology
10764-526: The study of historical or contemporary practices or of those traditions' ideas using intellectual tools and frameworks that are not themselves specifically tied to any religious tradition and that are normally understood to be neutral or secular. In contexts where 'religious studies' in this sense is the focus, the primary forms of study are likely to include: Sometimes, theology and religious studies are seen as being in tension, and at other times, they are held to coexist without serious tension. Occasionally it
10881-513: The study of the nature of what a Buddha is. In Mahayana Buddhism , a central concept in its buddhology is the doctrine of the three Buddha bodies (Sanskrit: Trikāya ). This doctrine is shared by all Mahayana Buddhist traditions. Within Hindu philosophy , there are numerous traditions of philosophical speculation on the nature of the universe, of God (termed Brahman , Paramatma , Ishvara , and/or Bhagavan in some schools of Hindu thought) and of
10998-402: The term natural theology , which denoted theology based on reasoning from natural facts independent of specifically Christian revelation) or that are specific to another religion (such as below). Theology can also be used in a derived sense to mean "a system of theoretical principles; an (impractical or rigid) ideology". The term theology has been deemed by some as only appropriate to
11115-521: The term passed into English in the 14th century, although it could also be used in the narrower sense found in Boethius and the Greek patristic authors, to mean rational study of the essential nature of God, a discourse now sometimes called theology proper . From the 17th century onwards, the term theology began to be used to refer to the study of religious ideas and teachings that are not specifically Christian or correlated with Christianity (e.g., in
11232-525: The texts of the Old Testament and the New Testament as well as on Christian tradition. Christian theologians use biblical exegesis, rational analysis and argument. Theology might be undertaken to help the theologian better understand Christian tenets, to make comparisons between Christianity and other traditions, to defend Christianity against objections and criticism, to facilitate reforms in
11349-1075: The theologies of the Goddess centered Shakta traditions which posit a feminine deity as the ultimate. In Japan, the term theology ( 神学 , shingaku ) has been ascribed to Shinto since the Edo period with the publication of Mano Tokitsuna's Kokon shingaku ruihen ( 古今神学類編 , 'categorized compilation of ancient theology'). In modern times, other terms are used to denote studies in Shinto—as well as Buddhist—belief, such as kyōgaku ( 教学 , 'doctrinal studies') and shūgaku ( 宗学 , 'denominational studies'). English academic Graham Harvey has commented that Pagans "rarely indulge in theology". Nevertheless, theology has been applied in some sectors across contemporary Pagan communities, including Wicca , Heathenry , Druidry and Kemetism . As these religions have given precedence to orthopraxy , theological views often vary among adherents. The term
11466-450: 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
11583-476: The university started to come under challenge during the European Enlightenment , especially in Germany. Other subjects gained in independence and prestige, and questions were raised about the place of a discipline that seemed to involve a commitment to the authority of particular religious traditions in institutions that were increasingly understood to be devoted to independent reason. Since
11700-423: The void and creating the real material bodies. 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
11817-578: 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
11934-498: 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
12051-440: The world, prefer the designation Buddhist philosophy to the term Buddhist theology , since Buddhism lacks the same conception of a theos or a Creator God . Jose Ignacio Cabezon, who argues that the use of theology is in fact appropriate, can only do so, he says, because "I take theology not to be restricted to discourse on God.... I take 'theology' not to be restricted to its etymological meaning. In that latter sense, Buddhism
12168-455: 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);
12285-399: 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
12402-483: 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
12519-430: 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
12636-402: 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,
12753-449: 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
12870-548: 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
12987-419: 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
13104-696: 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
13221-573: 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
13338-469: 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
13455-485: Was the ideal mental state for soldiers entering battle. Achieving ataraxia is a common goal for Pyrrhonism , Epicureanism , and Stoicism , but the role and value of ataraxia within each philosophy varies in accordance with their philosophical theories. The mental disturbances that prevent one from achieving ataraxia also vary among the philosophies, and each philosophy has a different understanding as to how to achieve ataraxia . In Pyrrhonism, ataraxia
13572-464: Was the study of church or canon law : universities played an important role in training people for ecclesiastical offices, in helping the church pursue the clarification and defence of its teaching, and in supporting the legal rights of the church over against secular rulers. At such universities, theological study was initially closely tied to the life of faith and of the church: it fed, and was fed by, practices of preaching , prayer and celebration of
13689-718: Was used with the meaning 'discourse on God' around 380 BC by Plato in The Republic . Aristotle divided theoretical philosophy into mathematike , physike , and theologike , with the latter corresponding roughly to metaphysics , which, for Aristotle, included discourse on the nature of the divine. Drawing on Greek Stoic sources, the Latin writer Varro distinguished three forms of such discourse: Some Latin Christian authors, such as Tertullian and Augustine , followed Varro's threefold usage. However, Augustine also defined theologia as "reasoning or discussion concerning
