 devoted young followers. In that dialogue, Socrates is presented as mentioning Plato by name as one of those youths close enough to him to have been corrupted, if he were in fact guilty of corrupting the youth, and questioning why their fathers and brothers did not step forward to testify against him if he was indeed guilty of such a crime (33d-34a). Later, Plato is mentioned along with Crito, Critobolus, and Apollodorus as offering to pay a fine of 30 minas on Socrates' behalf, in lieu of the death penalty proposed by Meletus (38b). In the Phaedo

 seem to present a somewhat different portrait of Socrates than Plato paints. Some have called attention to the problem of taking Plato's Socrates to be his mouthpiece, given Socrates' reputation for irony.

The precise relationship between Plato and Socrates remains an area of contention among scholars.

Philosophy


Recurrent Themes

Sanzio 01 Plato Aristotle
Plato often discusses the father-son relationship and the "question" of whether a father's interest in his sons has much to do with how well his sons turn out. A boy in ancient Athens 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 good character is a gift from the gods. 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 father-son relationship (Lysis 213a, Republic 3.403b), and in the Phaedo, Socrates' disciples, towards whom he displays more concern than his biological sons, say they will feel "fatherless" when he is gone. Many dialogues, like these, suggest that man-boy love (which is "spiritual") is a wise man's substitute for father-son biology (which is "bodily").

In several dialogues, Socrates floats the idea that Knowledge
Knowledge

Knowledge is defined in the Oxford English Dictionary as expertise, and skills acquired by a person through experience or education; the theoretical or practical understanding of a subject, what is known in a particular field or in total; facts and information or awareness or familiarity gained by experience of a fact or situation....
 is a matter of recollection, and not of learning, observation, or study. He maintains this view somewhat at his own expense, because in many dialogues, Socrates complains of his forgetfulness. Socrates is often found arguing that knowledge is not empirical, and that it comes from divine insight. He is quite consistent in believing in the immortality of the soul, and several dialogues end with long speeches imagining the afterlife
Afterlife

The afterlife is the concept of a continued existence for the soul, spirit or mind of a being after biological death. The major views on the afterlife derive from religion, esotericism and metaphysics....
. More than one dialogue contrasts knowledge and opinion, perception and reality

 and custom, and body and soul. The only contrast to this is his Parmenides.

Ion (dialogue)

In Plato's Ion Socrates discusses with the title character the question of whether the rhapsode, a professional performer of poetry, gives his performance on account of his skill and knowledge or by virtue of divine possession....
, 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.

On politics and art, religion and science, justice and medicine, virtue and vice, crime and punishment, pleasure and pain, rhetoric and rhapsody, human nature and sexuality, love and wisdom, Socrates and his company of disputants had something to say.

Metaphysics


"Platonism" is a term coined by scholars to refer to the intellectual consequences of denying, as Socrates often does, the reality of the material world. In several dialogues, most notably the Republic, Socrates inverts the common man's 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
Theaetetus (dialogue)

The The?tetus is one of Plato's Dialogues of Plato concerning the epistemology. The framing of the dialogue begins when Euclid of Megara tells his friend Terpsion that he had written a book many years ago based on what Socrates had told him of a conversation he'd had with Theaetetus when [Theaetetus] was quite a young man....
, he says such people are "eu a-mousoi", an expression that means literally, "happily without the muses" (Theaetetus 156a). In other words, such people live without the divine inspiration that gives him, and people like him, access to higher insights about reality.

Socrates's 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
Allegory of the cave

The Allegory of the Cave, also commonly known as Myth of the Cave, Metaphor of the Cave or the Parable of the Cave, is an allegory used by the Ancient Greece philosopher Plato in his work The Republic to illustrate "our nature in its education and want of education"....
, and more explicitly in his description of the divided line. The allegory of the cave (begins Republic 7.514a) is a paradoxical analogy wherein Socrates argues that the invisible world is the most intelligible ("noeton") and that the visible world ("(h)oraton") is the least knowable, and the most obscure. (This is exactly the opposite of what Socrates says to Euthyphro in the soothsayer's namesake dialogue. There, Socrates tells Euthyphro that people can agree on matters of logic and science, and are divided on moral matters, which are not so easily verifiable.)

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 that few climb out of the den, or cave of ignorance, and those who do, not only have a terrible struggle to attain the heights, but when they go back down for a visit or to help other people up, they find themselves objects of scorn and ridicule.

According to Socrates, physical objects and physical events are "shadows" of their ideal or perfect forms, and exist only to the extent that they instantiate the perfect versions of themselves. Just as shadows are temporary, inconsequential epiphenomena produced by physical objects, physical objects are themselves fleeting phenomena caused by more substantial causes, the ideals of which they are mere instances. For example, Socrates thinks that perfect justice exists (although it is not clear where) and his own trial would be a cheap copy of it.

The allegory of the cave (often said by scholars to represent Plato's own epistemology and metaphysics) is intimately connected to his political ideology (often said to also be Plato's own), that only people who have climbed out of the cave and cast their eyes on a vision of goodness are fit to rule. Socrates claims that the enlightened men of society must be forced from their divine contemplations and compelled to run the city according to their lofty insights. Thus is born the idea of the "philosopher-king", the wise person who accepts the power thrust upon him by the people who are wise enough to choose a good master. This is the main thesis of Socrates in the Republic, that the most wisdom the masses can muster is the wise choice of a ruler.

The word metaphysics derives from the fact that Aristotle's musings about divine reality came after ("meta") his lecture notes on his treatise on nature ("physics"). The term is in fact applied to Aristotle's own teacher, and Plato's "metaphysics" is understood as Socrates' division of reality into the warring and irreconcilable domains of the material and the spiritual. The theory has been of incalculable influence in the history of Western philosophy and religion.

. However, because Plato wrote dialogues, it is assumed that Socrates is often speaking for Plato. This assumption may not be true in all cases.

Plato, through the words of Socrates, asserts that societies have a tripartite class structure corresponding to the appetite/spirit/reason structure of the individual soul. The appetite/spirit/reason stand for different parts of the body. The body parts symbolize the castes of society.

  • Productive Which represents the abdomen.(Workers) — the labourers, carpenters, plumbers, masons, merchants, farmers, ranchers, etc. These correspond to the "appetite" part of the soul.
  • Protective Which represents the chest.(Warriors or Guardians) — those who are adventurous, strong and brave; in the armed forces. These correspond to the "spirit" part of the soul.
  • Governing Which represents the head. (Rulers or Philosopher Kings) — those who are intelligent, rational, self-controlled, in love with wisdom, well suited to make decisions for the community. These correspond to the "reason" part of the soul and are very few.


According to this model, the principles of Athenian democracy

Athenian democracy developed in the Ancient Greece city-state of Classical Athens, comprising the central city-state of Athens and the surrounding territory of Attica, around 500 BC....
 (as it existed in his day) are rejected as only a few are fit to rule. Instead of rhetoric and persuasion, 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,... nor, I think, will the human race." (Republic 473c-d)


Plato describes these "philosopher kings" as "those who love the sight of truth" (Republic 475c) and supports the idea with the analogy of a captain and his ship or a doctor and his medicine. Sailing and health are not things that everyone is qualified to practice by nature. A large part of the Republic then addresses how the educational system should be set up to produce these philosopher kings.

However, it must be taken into account that the ideal city outlined in the Republic is qualified by Socrates as the ideal luxurious city, examined to determine how it is that injustice and justice grow in a city (Republic 372e). According to Socrates, the "true" and "healthy" city is instead the one first outlined in book II of the Republic, 369c–372d, 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.

In addition, the ideal city is used as an image to illuminate the state of one's soul, or the will

Wherein it concerns states and rulers, Plato has made interesting arguments. For instance he asks which is better - a bad democracy or a country reigned by a tyrant. He argues that it is better to be ruled by a bad tyrant (since then there is only one person committing bad deeds) than be a bad democracy (since here all the people are now responsible for such actions.)

Unwritten Doctrine

] of the participant is different from what he says in his so-called unwritten teaching (???afa d??µata)." The term ???afa d??µata literally means unwritten doctrine and it stands for the most fundamental metaphysical teaching of Plato which he disclosed only to his most trusted fellows and kept secret from the public.

The reason for not revealing it to everyone is partially discussed in Phaedrus (276 c) where Plato criticizes the written transmission of knowledge as faulty, favoring instead the spoken logos
Logos

is an important term in philosophy, analytical psychology, rhetoric and religion.Heraclitus established the term in Western philosophy as meaning both the source and fundamental order of the cosmos....
: "he who has knowledge of the just and the good and beautiful ... will not, when in earnest, write them in ink, sowing them through a pen with words which cannot defend themselves by argument and cannot teach the truth effectually." The same argument is repeated in Plato's Seventh Letter (344 c): "every serious man in dealing with really serious subjects carefully avoids writing." In the same letter he writes (341 c): "I can certainly declare concerning all these writers who claim to know the subjects which I seriously study ... there does not exist, nor will there ever exist, any treatise of mine dealing therewith." Such secrecy is necessary in order not "to expose them to unseemly and degrading treatment" (344 d).

It is however said that Plato once disclosed this knowledge to the public in his lecture On the Good (?e?? t??a???), in which the Good (t? ??a???) is identified with the One (the Unity, t? ??), the fundamental ontological principle. The content of this lecture has been transmitted by several witnesses, among others Aristoxenus
Aristoxenus

Aristoxenus of Taranto was a Greek peripatetic philosopher, and writer on music and rhythm.He was taught first by his father Spintharus , a pupil of Socrates and also a musician, and later by the Pythagoras, Lamprus of Erythrae and Xenophilus, from whom he learned the theory of music....

 he writes: "Now since the Forms are the causes of everything else, he [i.e. Plato] supposed that their elements are the elements of all things. Accordingly the material principle is the Great and Small [i.e. the Dyad], and the essence is the One (t? ??), since the numbers are derived from the Great and Small by participation in the One" (987 b). "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, ? d???), the Great and Small (t? µ??a ?a? t? µ?????). Further, he assigned to these two elements respectively the causation of good and of evil" (988 a).

Works

Thirty-five dialogues and thirteen letters have traditionally been ascribed to Plato, though modern scholarship doubts the authenticity of at least some of these. Plato's writings have been published in several fashions; this has led to several conventions regarding the naming and referencing of Plato's texts.

The usual system for making unique references to sections of the text by Plato derives from a 16th century edition of Plato's works by Henricus Stephanus. An overview of Plato's writings according to this system can be found in the Stephanus pagination

 Lives 3.37). What is remarkable about Campbell's conclusions is that, in spite of all the stylometric studies that have been conducted since his time, perhaps the only chronological fact about Plato's works that can now be said to be proven by stylometry is the fact that Critias, Timaeus, Laws, Philebus, Sophist, and Statesman are the latest of Plato's dialogues, the others earlier.

Increasingly in the most recent Plato scholarship, writers are skeptical of the notion that the order of Plato's writings can be established with any precision, though Plato's works are still often characterized as falling at least roughly into three groups. The following represents one such division which is relatively common. It should, however, be kept in mind that many of the positions in the ordering are still highly disputed, and also that the very notion that Plato's dialogues can or should be "ordered" is by no means universally accepted.

Early dialogues
Socrates figures in all of these, and they are considered the most faithful representations of the historical Socrates; hence they are also called the Socratic dialogues. Most of them consist of Socrates discussing a subject, often an ethical one (friendship, piety) with a friend or with someone presumed to be an expert on it. Through a series of questions he will show that apparently they do not understand it at all. It is left to the reader to figure out if "he" really understands "it". This makes these dialogues "indirect" teachings.

Middle dialogues
Late in the early dialogues Plato's Socrates actually begins supplying answers to some of the questions he asks, or putting forth positive doctrines. This is generally seen as the first appearance of Plato's own views. The first of these, that goodness is wisdom and that no one does evil willingly, was perhaps Socrates' own view. What becomes most prominent in the middle dialogues is the idea that knowledge comes of grasping unchanging forms or essences, paired with the attempts to investigate such essences. The immortality of the soul, and specific doctrines about justice, truth, and beauty, begin appearing here. The Symposium and the Republic are considered the centrepieces of Plato's middle period. The Parmenides and Theaetetus

Late dialogues

The Parmenides presents a series of criticisms of the theory of Forms which are widely taken to indicate Plato's abandonment of the doctrine. Some recent publications (e.g., Meinwald (1991)) have challenged this characterisation. In most of the remaining dialogues the theory is either absent or at least appears under a different guise in discussions about kinds or classes of things (the Timaeus

, is that this is what philosophy is always in the business of doing, and is doing even in the early dialogues.

The late dialogues are also an important place to look for Plato's mature thought on most of the issues dealt with in the earlier dialogues. There is much work still to be done by scholars on the working out of what these views are. The later works are agreed to be difficult and challenging pieces of philosophy. On the whole they are more sober and logical than earlier works, but may hold out the promise of steps towards a solution to problems which were systematically laid out in prior works.

Narration of the dialogues

Plato never presents himself as a participant in any of the dialogues, and with the exception of the Apology
Apology (Plato)

Apology is Plato's version of the Speech given by Socrates as he defends himself against the charges of being a man "who corrupted the young, refused to worship the deity, and created new deities"....

, also begin in dramatic form but then proceed to virtually uninterrupted narration by followers of Socrates, and all, apparently, based on their distant memory or secondhand reports. Phaedo, an account of Socrates' final conversation and hemlock drinking, is narrated by Phaedo to Echecrates in a foreign city many years after the execution took place. The Symposium is narrated by Apollodorus, a Socratic disciple, apparently to Glaucon. Apollodorus assures his listener that he is recounting the story, which took place when he himself was an infant, not from his own memory, but as remembered by Aristodemus, who told him the story years ago. In the beginning of the Theaetetus (142c-143b), Euclides
Euclid of Megara

Euclid of Megara, , was a Ancient Greece Socrates philosopher who founded the Megarian school of philosophy. He was a pupil of Socrates in the late 5th century BC, and was present at his death....
 says that he compiled the conversation from notes he took based on what Socrates told him of his conversation with the title character. The rest of the Theaetetus is presented as a "book" written in dramatic form and read by one of Euclides' slaves (143c). Some scholars take this as an indication that Plato had by this date wearied of the narrated form. With the exception of the Theaetetus, Plato gives no explicit indication as to how these orally transmitted conversations came to be written down. Other dialogues, such as the Phaedo, Symposium, and Parmenides, do suggest that such conversations were faithfully recalled and transmitted by Socrates' followers.

Trial of Socrates

The trial of Socrates is the central, unifying event of the great Platonic dialogues. Because of this, Plato's Apology
Apology (Plato)

Apology is Plato's version of the Speech given by Socrates as he defends himself against the charges of being a man "who corrupted the young, refused to worship the deity, and created new deities"....
 is perhaps the most often read of the dialogues. In the Apology, Socrates tries to dismiss rumors that he is a sophist
Sophism

Sophism can mean two very different things: In the modern definition, a sophism is a confusing or illogical argument used for deceiving someone....
 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 of Athens.

Unity and Diversity of the Dialogues

If Plato's important dialogues do not refer to Socrates' execution explicitly, they allude to it, or use characters or themes that play a part in it. Five dialogues foreshadow the trial: In the Theaetetus
Theaetetus (dialogue)

The The?tetus is one of Plato's Dialogues of Plato concerning the epistemology.

Two other important dialogues, the Symposium
Symposium (Plato)

The Symposium is a philosophical dialogue written by Plato sometime after 385 BC. It is a discussion on the nature of love, taking the form of a group of speeches, both satirical and serious, given by a group of men at a symposium or a wine drinking gathering at the house of the Tragedy#Greek tragedy Agathon at Athens....

 slandered him in a comic play, and blames him for causing his bad reputation, and ultimately, his death. In the Symposium, the two of them are drinking together with other friends. The character Phaedrus is linked to the main story line by character (Phaedrus is also a participant in the Symposium and the Protagoras) and by theme (the philosopher as divine emissary, etc.) The Protagoras is also strongly linked to the Symposium by characters: all of the formal speakers at the Symposium (with the exception of Aristophanes) are present at the home of Callias in that dialogue.

 are present for the discussion in the Protagoras. Examples of characters crossing between dialogues can be further multiplied. The Protagoras contains the largest gathering of Socratic associates.

In the dialogues for which Plato is most celebrated and admired, 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
Cratylus (dialogue)

Cratylus is the name of a dialogue by Plato. Most modern scholars agree that it was written mostly during Plato's so-called middle period....

Cratylus was an History of Athens philosopher from late 5th century BC, mostly known through his portrayal in Plato's dialogue Cratylus . Little is known of Cratylus or his mentor Heraclitus ....
 (384b-c), Socrates says that he studied with Cratylus, and took his one-drachma course because he could not afford the full fifty-drachma course. Socrates' ideas are also not consistent within or between or among dialogues.
