According to Burnet, the opening scene of the Charmides is a glorication of the whole [family] connection Platos dialogues are not only a memorial to Socrates, but also the happier days of his own family.

According to Diogenes Lartius, the philosopher was named Aristocles after his grandfather. It was common in Athenian society for boys to be named after grandfathers or fathers. There no record of a line from Aristocles to Platos father, Ariston.

However, if Plato was not named after an ancestor named Plato there is no record of one , then the origin of his renaming as Plato Pythagoras, depicted as a medieval scholar in the Nuremberg Chronicle becomes a conundrum. The sources of Diogenes account for this fact by claiming that his wrestling coach, Ariston of Argos, dubbed him Platon, meaning broad, on account of his robust gure[22] or that Plato derived his name from the breadth , platyts of his eloquence, or else because he was very wide , plats across the forehead.

The fact that the philosopher in his maturity called himself Platon is indisputable, but the origin of this naming must remain moot unless the record is made to yield more information.

Apuleius informs us that Speusippus praised Platos quickness of mind and modesty as a boy, and the rst fruits of his youth infused with hard work and love of study. Although Socrates inuenced Plato directly as related in the dialogues, the inuence of Pythagoras upon Plato also appears to have signicant discussion in the philosophical literature.

Pythagoras, or in a broader sense, the Pythagoreans, allegedly exercised an important inuence on the work of Plato. According to R. Hare, this inuence consists of three points: 1 The platonic Republic might be related to the idea of a tightly organized community of like-minded thinkers, like the one established by Pythagoras in Croton.

It is probable that both were inuenced by Orphism. Pythagoras on Plato and others was so great that he and Aristophanes seem to present a somewhat dierent should be considered the most inuential of all Western portrait of Socrates from the one Plato paints. Some have philosophers. Aristotle attributes a dierent doctrine with respect to the Ideas to Plato and Socrates Metaphysics b Main article: Socratic problem Putting it in a nutshell, Aristotle merely suggests that The precise relationship between Plato and Socrates reSocrates idea of forms can be discovered through investigation of the natural world, unlike Platos Forms that exist beyond and outside the ordinary range of human understanding.

One story is that the name of the Academy comes from the ancient hero, Academus. Another story is that the name came from a supposed a former owner, a citizen of Athens also named Academus. Yet another account is that it was named after a member of the army of Castor and Pollux, an Arcadian named Echedemus.

NeoplaPlato and Socrates in a medieval depiction tonists revived the Academy in the early 5th century, and it operated until AD , when it was closed by Justinian mains an area of contention among scholars. Plato makes I of Byzantium, who saw it as a threat to the propagation it clear in his Apology of Socrates, that he was a devoted of Christianity.

Many intellectuals were schooled in the young follower of Socrates. In that dialogue, Socrates is Academy, the most prominent one being Aristotle. According to Diogenes were in fact guilty of corrupting the youth, and question- Laertius, Plato initially visited Syracuse while it was uning why their fathers and brothers did not step forward der the rule of Dionysius.

Later, Plato is mentioned along with Platos disciples, but the tyrant himself turned against Crito, Critobolus, and Apollodorus as oering to pay a Plato. Plato almost faced death, but he was sold into slavne of 30 minas on Socrates behalf, in lieu of the death ery, then Anniceris[42] bought Platos freedom for twenty penalty proposed by Meletus 38b. In the Phaedo, the minas,[43] and sent him home.

After Dionysiuss death, title character lists those who were in attendance at the according to Platos Seventh Letter, Dion requested Plato prison on Socrates last day, explaining Platos absence return to Syracuse to tutor Dionysius II and guide him to by saying, Plato was ill. Phaedo 59b become a philosopher king. Dionysius II seemed to acPlato never speaks in his own voice in his dialogues.

In the Second Letter, it says, no writing of Plato exists or ever will exist, but those now said to be his are those of a Socrates become beautiful and new c ; if the Letter is Platos, the nal qualication seems to call into question the dialogues historical delity. In any case, Xenophon. Dionysius expelled Dion and kept Plato against his will. Eventually Plato left Syracuse. Dion would return to overthrow Dionysius and ruled Syracuse for a short time before being usurped by Calippus, a fellow disciple of Plato.

A variety of sources have given accounts of Platos death. One story, based on a mutilated manuscript,[44] suggests Plato died in his bed, whilst a young Thracian girl played the ute to him. The account is based on Diogenes Laertiuss reference to an account by Hermippus, a thirdcentury Alexandrian. Crito reminds Socrates that orphans are at the mercy of chance, but Socrates is unconcerned. In the Theaetetus, he is found recruiting as a disciple a young man whose inheritance has been squandered.

Socrates twice compares the relationship of the older man and his boy lover to the fatherson relationship Lysis a, Republic 3. In several of Platos dialogues, Socrates promulgates the idea that knowledge is a matter of recollection, and not of learning, observation, or study. Socrates is often found arguing that knowledge is not empirical, and that it comes from divine insight.

In many middle period dialogues, such as the Phaedo, Republic and Phaedrus Plato advocates a belief in the immortality of the soul, and several dialogues end with long speeches imagining the afterlife. More than one dialogue contrasts knowledge and opinion, perception and reality, nature and custom, and body and soul.

Several dialogues tackle questions about art: Socrates says that poetry is inspired by the muses, and is not rational. He speaks approvingly of this, and other forms of divine madness drunkenness, eroticism, and dreaming in the Phaedrus ac , and yet in the Republic wants to outlaw Homers great poetry, and laughter as well. In Ion, Socrates gives no hint of the disapproval of Homer that he expresses in the Republic. The dialogue Ion suggests that Homer's Iliad functioned in the ancient Greek world as the Bible does today in the modern Christian world: as divinely inspired literature that can provide moral guidance, if only it can be properly interpreted.

Socrates and his company of disputants had something to say on many subjects, including politics and art, religion and science, justice and medicine, virtue and vice, Plato left and Aristotle right , a detail of The School of crime and punishment, pleasure and pain, rhetoric and Athens, a fresco by Raphael.

Aristotle gestures to the earth, reprhapsody, human nature and sexuality, as well as love and resenting his belief in knowledge through empirical observation and experience, while holding a copy of his Nicomachean Ethics wisdom. Plato holds his Timaeus and gestures to the heavens, representing his belief in The Forms. Plato often discusses the father-son relationship and the question of whether a fathers interest in his sons has much to do with how well his sons turn out.

In ancient Athens, a boy was socially located by his family identity, and Plato often refers to his characters in terms of their paternal and fraternal relationships.

Socrates was not a family man, and saw himself as the son of his mother, who was apparently a midwife. A divine fatalist, Socrates mocks men who spent exorbitant fees on tutors and trainers for their sons, and repeatedly ventures the idea that. In several dialogues, most notably the Republic, Socrates inverts the common mans intuition about what is knowable and what is real.

While most people take the objects of their senses to be real if anything is, Socrates is contemptuous of people who think that something has to be graspable in the hands to be real.

In the Theaetetus, he says such people are eu amousoi , an expression that means. In other words, such people live without the divine inspiration that gives him, and people like him, access to higher insights about reality.

The forms, according to Socrates, are archetypes or abstract representations of the many types of things, and properties we feel and see around us, that can only be perceived by reason Greek:. That is, they are universals. In other words, Socrates was able to recognize two worlds: the apparent world, which constantly changes, and an unchanging and unseen world of forms, which may be the cause of what is apparent. Socratess idea that reality is unavailable to those who use their senses is what puts him at odds with the common man, and with common sense.

Socrates says that he who sees with his eyes is blind, and this idea is most famously captured in his allegory of the cave, and more explicitly in his description of the divided line. The allegory of the cave begins Republic 7. Main article: Platonic epistemology Socrates says in the Republic that people who take the sun-lit world of the senses to be good and real are living pitifully in a den of evil and ignorance. Socrates admits Many have interpreted Plato as statingeven having that few climb out of the den, or cave of ignorance, and been the rst to writethat knowledge is justied true those who do, not only have a terrible struggle to attain belief, an inuential view that informed future develop[48] This interpretation is partly the heights, but when they go back down for a visit or ments in epistemology.

And this theory may events are shadows of their ideal or perfect forms, and again be seen in the Meno, where it is suggested that true exist only to the extent that they instantiate the perfect belief can be raised to the level of knowledge if it is bound versions of themselves.

Just as shadows are temporary, with an account as to the question of why the object inconsequential epiphenomena produced by physical obof the true belief is so Meno 97d98a.

For example, Socrates thinks That the modern theory of justied true belief as knowlthat perfect justice exists although it is not clear where edge which Gettier addresses is equivalent to Platos is acand his own trial would be a cheap copy of it. Socrates claims that the enlightened men Later in the Meno, Socrates uses a geometrical example to of society must be forced from their divine contemplaexpound Platos view that knowledge in this latter sense tions and be compelled to run the city according to their is acquired by recollection.

Socrates elicits a fact conlofty insights. Thus is born the idea of the "philosophercerning a geometrical construction from a slave boy, who king", the wise person who accepts the power thrust upon could not have otherwise known the fact due to the slave him by the people who are wise enough to choose a good boys lack of education.

The knowledge must be present, master. This is the main thesis of Socrates in the RepubSocrates concludes, in an eternal, non-experiential form.

In other words, if one deThe theory of Forms or theory of Ideas typically refers rives ones account of something experientially, because to the belief that the material world as it seems to us is the world of sense is in ux, the views therein attained not the real world, but only an image or copy of the will be mere opinions.

And opinions are characterized real world. In some of Platos dialogues, this is expressed by a lack of necessity and stability. On the other hand,. That apprehenwith wisdom, well suited to make decisions for the sion of forms is required for knowledge may be taken to community. These correspond to the reason part cohere with Platos theory in the Theaetetus and Meno.

Indeed, the apprehension of Forms may be at the base of the account required for justication, in that it oers In the Timaeus, Plato locates the parts of the soul within foundational knowledge which itself needs no account, the human body: Reason is located in the head, spirit in thereby avoiding an innite regression.

According to this model, the principles of Athenian democracy as it existed in his day are rejected as only Main article: The Republic Plato a few are t to rule. Instead of rhetoric and persuasion, Platos philosophical views had many societal implica- Plato says reason and wisdom should govern.

As Plato puts it: Until philosophers rule as kings or those who are now called kings and leading men genuinely and adequately philosophise, that is, until political power and philosophy entirely coincide, while the many natures who at present pursue either one exclusively are forcibly prevented from doing so, cities will have no rest from evils, Republic c-d.

There is some discrepancy between his early and later views. Some of the most famous doctrines are contained in the Republic during his middle period, as well as in the Laws and the Statesman. However, because Plato wrote dialogues, it is assumed that Socrates is often speaking for Plato.

This assumption may not be true in Plato in his academy, drawing after a painting by Swedish painter all cases. Carl Johan Wahlbom. Plato describes these philosopher kings as those who love the sight of truth Republic c and supports the idea with the analogy of a captain and his ship or a doctor and his medicine.

According to him, sailing and health are not things that everyone is qualied to practice by na Productive Workers the labourers, carpenters, ture. A large part of the Republic then addresses how plumbers, masons, merchants, farmers, ranchers, the educational system should be set up to produce these etc.

These correspond to the appetite part of the philosopher kings. However, it must be taken into account that the ideal Protective Warriors or Guardians those who are city outlined in the Republic is qualied by Socrates as adventurous, strong and brave; in the armed forces. According to Socrates, the true and healthy city is instead the one rst outlined in book II of the Republic, cd, containing farmers, craftsmen, merchants, and wage-earners, but lacking the guardian class of philosopher-kings as well as delicacies such as perfumed oils, incense, prostitutes, and pastries, in addition to paintings, gold, ivory, couches, a multitude of occupations such as poets and hunters, and war.

It is characterized by an undisciplined society existing in chaos, where the tyrant rises as popular champion leading to the formation of his private army and the growth of oppression.

In addition, the ideal city is used as an image to illuminate the state of ones soul, or the will, reason, and desires combined in the human body. Socrates is attempting to make an image of a rightly ordered human, and then later goes on to describe the dierent kinds of humans that can be observed, from tyrants to lovers of money in various kinds of cities. The ideal city is not promoted, but only used to magnify the dierent kinds of individual humans and the state of their soul.

However, the philosopher king image was used by many after Plato to justify their personal political beliefs. The philosophic soul according to Socrates has reason, will, and desires united in virtuous harmony. A philosopher has the moderate love for wisdom and the courage to act according to wisdom. Wisdom is knowledge about the Good or the right relations between all that exists.

According to Plato, a state made up of dierent kinds of souls will, overall, decline from an aristocracy rule by the best to a timocracy rule by the honorable , then to an oligarchy rule by the few , then to a democracy rule by the people , and nally to tyranny rule by one person, rule by a tyrant.

This regime is ruled by a philosopher king, and thus is grounded on wisdom and reason. In Book VIII, Plato states in order the other four imperfect societies with a description of the states structure and individual character.

In timocracy the ruling class is made up primarily of those with a warrior-like character. Oligarchy is made up of a society in which wealth is the criterion of merit and the wealthy are in control. Such secrecy is necessary in order not to expose them to unseemly and degrading treatment d. For a long time, Platos unwritten doctrine[65][66][67] had been controversial. Many modern books on Plato seem to diminish its importance; nevertheless, the rst important witness who mentions its existence is Aristotle, who in his Physics b writes: It is true, indeed, that the account he gives there [i.

The term " " literally means unwritten doctrines and it stands for the most fundamental metaphysical teaching of Plato, which he disclosed only orally, and some say only to his most trusted fellows, and which he may have kept secret from the public.

The importance of the unwritten doctrines does not seem to have been seriously questioned before Wherein it concerns states and rulers, Plato has made the 19th century. For instance he asks which is A reason for not revealing it to everyone is partially disbettera bad democracy or a country reigned by a tyrant. This is emphasised within write them in ink, sowing them through a pen with words, the Republic as Plato describes the event of mutiny on which cannot defend themselves by argument and canboard a ship.

The same argument is line with the democratic rule of many and the captain, repeated in Platos Seventh Letter c : every serialthough inhibited through ailments, the tyrant.

Platos ous man in dealing with really serious subjects carefully description of this event is parallel to that of democracy avoids writing. In the same letter he writes c : I within the state and the inherent problems that arise. It is, however, said that Plato once disclosed this knowledge to the public in his lecture On the Good , in which the Good is identied with the One the Unity, , the fundamental ontological principle.

The content of this lecture has been transmitted by several witnesses. Aristoxenus describes the event in the following words: Each came expecting to learn something about the things that are generally considered good for men, such as wealth, good health, physical strength, and altogether a kind of wonderful happiness.

But when the mathematical demonstrations came, including numbers, geometrical gures and astronomy, and nally the statement Good is One seemed to them, I imagine, utterly unexpected and strange; hence some belittled the matter, while others rejected it.

In Metaphysics he writes: Now since the Forms are the causes of everything else, he [i. Plato] supposed that their elements are the elements of all things. Accordingly the material principle is the Great and Small [i. From this account it is clear that he only employed two causes: that of the essence, and the material cause; for the Forms are the cause of the essence in everything else, and the One is the cause of it in the Forms. He also tells us what the material substrate is of which the Forms are predicated in the case of sensible things, and the One in that of the Forms - that it is this the duality the Dyad, , the Great and Small.

Further, he assigned to these two elements respectively the causation of good and of evil a. Hartzs is a teleological interpretation at the core, in which philosophers will ultimately exhaust the available body of knowledge and thus reach the end of history. Karl Popper, on the other hand, claims that dialectic is the art of intuition for visualising the divine originals, the Forms or Ideas, of unveiling the Great Mystery behind the common mans everyday world of appearances.

The usual system for making unique references to sections of the text by Plato derives from a 16th-century edition of Platos works by Henricus Stephanus. An overview of Platos writings according to this system can be found in The most important aspect of this interpretation of Platos the Stephanus pagination article. This scheme is ascribed by Diowhich has been considered erroneous by many but may genes Laertius to an ancient scholar and court astrologer in fact have been directly inuenced by oral transmission to Tiberius named Thrasyllus.

A modern scholar who recognized by the importance of the unwritten doctrine of Plato was The works are usually grouped into Early, sometimes [77][78] some into Transitional , Middle, and Late period. Heinrich Gomperz who described it in his speech during is thought worthy of the 7th International Congress of Philosophy in These sources have subsequently [80] writing are not condently ascertained. The role of dialectic in Platos thought is contested but there are two main interpretations: a type of reasoning and a method of intuition.

Each new idea exposes a aw in the accepted. Plato is not the author of the work. Three dialogues are often considered transiThe following works were transmitted under Platos tional or pre-middle": Euthydemus, Gorgias, and Meno. These works are labelled as clude in aporia, the so-called middle dialogues provide more clearly stated positive teachings that are often asNotheuomenoi spurious or Apocrypha.

A signicant distinction of though it does not relate to the theory of Forms in the the early Plato and the later Plato has been oered by same way. The rst book of the Republic is often thought scholars such as E.

Dodds and has been summarized to have been written signicantly earlier than the rest of by Harold Bloom in his book titled Agon: E. Dodds is the work, although possibly having undergone revisions the classical scholar whose writings most illuminated the when the later books were attached to it. This grouping is the only one proven by styist of the Protagoras to the transcendental psychologist, lometric analysis.

Some scholars[91] indi[85] Lewis Campbell was the rst to make exhaustive cate that the theory of Forms is absent from the late diuse of stylometry to prove objectively that the Critias, alogues, its having been refuted in the Parmenides, but Timaeus, Laws, Philebus, Sophist, and Statesman were there isn't total consensus that the Parmenides actually all clustered together as a group, while the Parmenides, refutes the theory of Forms.

Diogenes Laertius Lives 3. What is remarkable about Campbells conclusions is that, in spite 3. Some dialogues have no narrator but the others earlier.

Phaedrus, Crito, Euthyphro , some dialogues are narrated by Socrates, wherein he speaks in rst person examples: Lysis, Charmides, Republic. One dialogue, Protagoras, begins in dramatic form but quickly proceeds to Socrates. Five dialogues foreshadow the trial: In the Theaetetus d and the Euthyphro 2a b Socrates tells people that he is about to face corruption charges. In the Meno 94e95a , one of the men who brings legal charges against Socrates, Anytus, warns him about the trouble he may get into if he does not stop criticizing important people.

In the Gorgias, Socrates says that his trial will be like a doctor prosecuted by a cook who asks a jury of children to choose between the doctors bitter medicine and the cooks tasty treats e Platos Symposium Anselm Feuerbach, a.

Charmides and his guardian Critias are be written down. Examples of characters crossing between dialogues can be further multiplied. The Protagoras contains the largest gathering 3.

Main article: Trial of Socrates In the dialogues Plato is most celebrated and admired for, The trial of Socrates is the central, unifying event of the great Platonic dialogues. Because of this, Platos Apology is perhaps the most often read of the dialogues. In the Apology, Socrates tries to dismiss rumors that he is a sophist and defends himself against charges of disbelief in the gods and corruption of the young.

Socrates insists that long-standing slander will be the real cause of his demise, and says the legal charges are essentially false. Socrates famously denies being wise, and explains how his life as a philosopher was launched by the Oracle at Delphi.

He says that his quest to resolve the riddle of the oracle put him at odds with his fellow man, and that this is the reason he has been mistaken for a menace to the city-state.

Socrates is concerned with human and political virtue, has a distinctive personality, and friends and enemies who travel with him from dialogue to dialogue.

This is not to say that Socrates is consistent: a man who is his friend in one dialogue may be an adversary or subject of his mockery in another. For example, Socrates praises the wisdom of Euthyphro many times in the Cratylus, but makes him look like a fool in the Euthyphro. He disparages sophists generally, and Prodicus specically in the Apology, whom he also slyly jabs in the Cratylus for charging the hefty fee of fty drachmas for a course on language and grammar.

However, Socrates tells Theaetetus in his namesake dialogue that he admires Prodicus and has directed many pupils to him. Socrates ideas are also. Many of these comments on Plato were translated from Arabic into Latin and as such inuenced Medieval scholastic philosophers. Many of the greatest early modern scientists and artists who broke with Scholasticism and fostered the owering of the Renaissance, with the support of the Platoinspired Lorenzo grandson of Cosimo , saw Platos philosophy as the basis for progress in the arts and sciences.

His political views, too, were well-received: the vision of wise philosopher-kings of the Republic matched the views set out in works such as Machiavelli's The Prince. More problematic was Platos belief in metempsychosis, transmigration of the soul, as well as his ethical views on polyamory and euthanasia in particular , which did not match those of Christianity. It was Plethons student Bessarion who reconciled Plato with Christian theology, arguing that Platos views were only ideals, unattainable due to the fall of man.

The safest general characterisation of the European philosophical tradition is that it consists of a series of footnotes to Plato. Alfred North Whitehead, Process and Reality, Although their popularity has uctuated over the years, the works of Plato have never been without readers since the time they were written.

However, in the Byzantine Empire, the study of Plato continued. The only Platonic work known to western scholarship was Timaeus, until translations were made at a time post the fall of Constantinople, which occurred during ,[98] George Gemistos Plethon brought Platos original writings from Constantinople in the century of its fall.

It is believed that Plethon passed a copy of the Dialogues to Cosimo de' Medici when in the Council of Ferrara, called to unify the Greek and Latin Churches, was adjourned to Florence, where Plethon then lectured on the relation and dierences of Plato and Aristotle, and red Cosimo with his enthusiasm;[99] Cosimo would. By the 19th century, Platos reputation was restored, and at least on par with Aristotles. Notable Western philosophers have continued to draw upon Platos work since that time.

Platos inuence has been especially strong in mathematics and the sciences. He helped to distinguish between pure and applied mathematics by widening the gap between arithmetic, now called number theory and logistic, now called arithmetic. He regarded logistic as appropriate for business men and men of war who must learn the art of numbers or he will not know how to array his troops, while arithmetic was appropriate for philosophers because he has to arise out of the sea of change and lay hold of true being.

Albert Einstein suggested that the scientist who takes philosophy seriously would have to avoid systematization and take on many dierent roles, and possibly appear as a Platonist or Pythagorean, in that such a one would have the viewpoint of logical simplicity as an indispensable and eective tool of his research.

A number of these postmodern philosophers have thus appeared to disparage Platonism from more or less informed perspectives. Friedrich Nietzsche notoriously attacked Platos idea of the good itself along with many fundamentals of Christian morality, which he interpreted as Platon-. Martin Heidegger argued against Platos alleged obfuscation of Being in his incomplete tome, Being and Time , and the philosopher of science Karl Popper argued in The Open Society and Its Enemies that Platos alleged proposal for a utopian political regime in the Republic was prototypically totalitarian.

The political philosopher and professor Leo Strauss is considered by some as the prime thinker involved in the recovery of Platonic thought in its more political, and less metaphysical, form. Strauss political approach was in part inspired by the appropriation of Plato and Aristotle by medieval Jewish and Islamic political philosophers, especially Maimonides and Al-Farabi, as opposed to the Christian metaphysical tradition that developed from Neoplatonism.

Deeply inuenced by Nietzsche and Heidegger, Strauss nonetheless rejects their condemnation of Plato and looks to the dialogues for a solution to what all three latter day thinkers acknowledge as 'the crisis of the West.

These sources are medieval manuscripts written on vellum mainly from 9thth century AD Byzantium , papyri mainly from late antiquity in Egypt , and from the independent testimonia of other authors who quote various segments of the works which come from a variety of sources.

The text as presented is usually not much dierent from what appears in the Byzantine manuscripts, and papyri and testimonia just conrm the manuscript tradition. In some editions however the readings in the papyri or testimonia are favoured in some places by the editing critic of the text.

Reviewing editions of papyri for the Republic in , Slings suggests that the use of papyri is hampered due to some poor editing practices. While it has not survived to the present day, all the extant medieval Greek manuscripts are based on his edition.

Platos tripartite theory of soul Let us at the same time reect, seeing that Platonic Academy Providence rescues from its perils the world. Plato himself, by taking pains, advanced to old age. To be sure, he was the fortunate possessor of a strong and sound body his very name was given him because of his broad chest ; but his strength was much impaired by sea voyages and desperate adventures.

Nevertheless, by frugal living, by setting a limit upon all that rouses the appetites, and by painstaking attention to himself, he reached that advanced age in spite of many hindrances. Diogenes mentions as one of his sources the Universal History of Favorinus. According to Favorinus, Ariston, Platos family, and his family were sent by Athens to settle as cleruchs colonists retaining their Athenian citizenship , on the island of Aegina, from which they were expelled by the Spartans after Platos birth there.
