Socratic philosophy
Socrates
Σωκράτης
c. 469 BCE – 399 BCEHistorically documented person
Athenian philosopher (c. 469–399 BCE) who wrote nothing and changed the course of philosophy by making the question of how one should live its central concern. He conversed in the agora, examining those who believed they knew, without charging fees. Accused of impiety and of corrupting the young, he was sentenced to death and drank hemlock. We know him through Plato, Xenophon, Aristophanes and Aristotle, whose portraits disagree: the "Socratic problem".

The man who wrote nothing
Socrates left not a single written line. Everything we know about him comes from others: from the dialogues of his pupil Plato, from Xenophon's Socratic works, from the comedy in which Aristophanes mocked him in his lifetime, from the reports Aristotle—born fifteen years after his death—gathered in the Academy, and from the late compilation of Diogenes Laertius in the third century CE. These witnesses do not agree. Aristophanes' Socrates is a charlatan who speculates about the clouds and teaches how to win unjust lawsuits; Xenophon's is a sensible moralist who gives his friends sound advice; Plato's is a thinker of incomparable depth who, in the late dialogues, becomes the mouthpiece for doctrines he probably never held.
This gap between the sources is called the "Socratic problem". Friedrich Schleiermacher formulated it in 1818, asking what Socrates must have been for Plato and Xenophon to portray him as they did. Since then some have trusted Xenophon for his apparent sobriety; others, like Gregory Vlastos, have reconstructed a historical Socrates from Plato's early dialogues; and others, like Olof Gigon or Charles Kahn, have stressed that "Socratic discourses" were a literary genre practised by several disciples, none of whom meant to keep minutes. What follows separates, as far as possible, what the sources share from what each contributes.
Alopece
He was born in Athens around 469 BCE—Diogenes Laertius, following Apollodorus' chronology, places the birth in the fourth year of the 77th Olympiad—in the deme of Alopece, of the tribe Antiochis. His father, Sophroniscus, was a stonemason or sculptor; his mother, Phaenarete, a midwife, a craft Socrates himself would turn into an image of his method in the Theaetetus. He married Xanthippe late and had three sons by her—Lamprocles, Sophroniscus and Menexenus; Aristotle, quoted by Diogenes, also credits him with a second wife, Myrto, a report scholars consider doubtful.
He grew up in the Athens of Pericles, in the generation that saw the Parthenon rise and tragedy, sophistry and the inquiry into nature flourish. Plato has him converse as a young man with Parmenides and Zeno, probably a literary encounter, and presents him as interested in his youth in Anaxagoras' physics, which he supposedly abandoned because it gave no answer to the question of the good.
Soldier and citizen
He served as a hoplite, which implies some means in his youth. He fought at Potidaea (432–430 BCE), where, according to the account Plato gives Alcibiades in the Symposium, he saved Alcibiades' life and endured the winter barefoot; in the retreat from Delium (424 BCE), where his composure impressed the generals; and at Amphipolis (422 BCE). The Apology recalls these three campaigns as proof that he never deserted the post assigned to him.
He held only one public office, and by lot. In 406 BCE, as a member of the Council during his tribe's prytany, he opposed trying en bloc, against the law, the generals who had won at Arginusae, accused of failing to rescue the shipwrecked. Two years later, under the oligarchy of the Thirty, he and four others were ordered to arrest Leon of Salamis for execution, and he went home. Plato and Xenophon agree on both episodes.
Questioning as a calling
His calling was conversation. He practised it in the agora, in the gymnasia and in his friends' houses, without charging fees—unlike the sophists, with whom many confused him—and in a poverty the Apology calls extreme. His ugliness was famous: snub nose, bulging eyes, the look of a silenus. According to the Apology, his friend Chaerephon asked at Delphi whether anyone was wiser than Socrates and the Pythia answered no; Socrates, puzzled, examined politicians, poets and craftsmen, and concluded that his only advantage was not thinking he knew what he did not know. From then on he understood his examination of others as a service to the god.
That examination—the elenchus—consisted in asking for a definition of courage, piety or justice, obtaining the interlocutor's assent to other propositions and showing him that the initial definition was inconsistent with them. Aristotle credits him with two contributions: inductive arguments and the search for universal definitions, applied to moral questions, without separating those universals from things, as Plato would with the Forms. Socrates also spoke of a divine sign, his daimonion, a voice that since childhood had held him back from certain acts and never urged him to do anything.
The Clouds
In 423 BCE Aristophanes staged the Clouds, in which a Socrates suspended in a basket runs a "thinkery" where celestial phenomena are studied, Zeus is replaced by vortices and the unjust argument is taught. The comedy came third, but the caricature survived: in the Apology Socrates counts among his "first accusers" those who spread that image and names the comic poet explicitly. His association with Alcibiades, who betrayed Athens, and with Critias, the most radical of the Thirty, also weighed against him.
The trial
In the spring of 399 BCE Meletus, backed by Anytus and Lycon, accused him of not recognising the city's gods, of introducing new divinities and of corrupting the young; he asked for the death penalty. Since the amnesty of 403 barred prosecution for earlier political offences, the charge was framed in religious terms. Before a jury of some five hundred citizens Socrates defended himself without pleas or tears. He was convicted by a margin of about sixty votes, as can be inferred from Plato's Apology; invited to propose an alternative penalty, he first suggested being maintained at public expense in the Prytaneum and then a fine of thirty minae guaranteed by Plato, Crito, Critobulus and Apollodorus. The jury voted for death.
The execution was postponed for about thirty days because the sacred ship sent to Delos had not returned, and the city could execute no one in its absence. Crito offered him escape, and Socrates refused: in the dialogue that bears Crito's name, the Laws of Athens remind him that he has lived seventy years under their protection and may not answer one injustice with another.
The death
The Phaedo narrates the last day. Plato was not present—"Plato, I believe, was ill", says the narrator—and the dialogue, centred on proofs of the soul's immortality, is a work of art and doctrine rather than a record. Towards evening Socrates bathed, said farewell to his wife and sons, drank the poison—hemlock, by the traditional identification—and walked about until his legs felt heavy. As the cold rose towards his heart he uncovered his face and told Crito that they owed a cock to Asclepius and must not forget to pay it. They were, according to Phaedo, his last words.
What remained
His circle gave rise to rival schools: Plato's Academy, the Cynics who claimed descent from Antisthenes, Aristippus' Cyrenaics, Euclides' Megarians. The Stoics held him up as the model sage, and Epictetus quotes him constantly. In modern times Kierkegaard devoted his dissertation to Socratic irony (1841), Nietzsche made him the symptom of a decadence (1889) and Jacques-Louis David fixed in 1787 the image of his serene death. He remains, for the Western tradition, the figure of the philosopher who preferred death to ceasing to examine life.

Apology of Socrates
Ἀπολογία Σωκράτους
Socrates' defence speech before the Athenian court in 399 BCE, in three parts: the defence against the "first accusers" and against Meletus; the counter-proposal of a penalty after the verdict; and closing words to the jurors. It contains the account of the Delphic oracle, the image of the gadfly that rouses the city, the statement that he will obey the god rather than the Athenians and the dictum that the unexamined life is not worth living. It is the main source for reconstructing the trial and Socrates' understanding of himself.

Crito
Κρίτων
In prison, at dawn, his old friend Crito tells Socrates that the ship from Delos is about to arrive and offers him an escape, already arranged and paid for. Socrates examines whether it is just to flee: one must not answer an injustice with another, and the personified Laws of Athens remind him that for seventy years he has accepted living under them. It is the classic text on the obligation to obey the law and one of the first arguments about the compact between citizen and city.

Recorded oral teaching · c. 385 BCE
Phaedo
Φαίδων
Account of Socrates' last day, told by Phaedo of Elis to Echecrates at Phlius. Socrates talks with the Thebans Simmias and Cebes, who had frequented Pythagoreans, about why the philosopher does not fear death, and sets out four arguments for the immortality of the soul and a myth about the fate of souls. The dialogue closes with the death scene: the bath, the farewell to his family, the cup of poison and the last words to Crito about the cock owed to Asclepius (118a).

Memorabilia (Memoirs of Socrates)
Ἀπομνημονεύματα
Four books that begin by refuting one by one the charges of impiety and corruption of the young, and go on to dozens of short conversations: Socrates advises his son Lamprocles to be patient with Xanthippe, talks with the sophist Antiphon about poverty, with Aristippus about self-mastery, with craftsmen and generals about their trades. It is the portrait of a practical and pious teacher and the second great source on Socrates alongside Plato.

Apocryphal quotes or disputed attributions (5)
«I know that I know nothing.»
The formula appears in no ancient text about Socrates. It is a later simplification of Apology 21d, where Socrates says something more precise: that he does not think he knows what he does not know. In Plato Socrates claims to know some things (for instance, that doing wrong is bad, Apology 29b).
«Know thyself.»
It is one of the maxims inscribed at the temple of Apollo at Delphi, older than Socrates and ascribed in antiquity to several of the Seven Sages. Socrates quotes and discusses it (Phaedrus 229e, Charmides 164d), but it is not his.
«There is only one good, knowledge, and one evil, ignorance.»
Only Diogenes Laertius (II 31) transmits it, more than six centuries later and without naming a source. It sums up Socratic intellectualism as a slogan, but it is not found in Plato or Xenophon.
«Education is the kindling of a flame, not the filling of a vessel.»
Attributed to Socrates online, it comes from Plutarch, On Listening (Moralia 48c), who says the mind is not a vessel to be filled but kindling to be set alight. Plutarch lived five centuries later.
«The "triple filter test": before you tell me something, is it true, is it good, is it useful?»
A moralising anecdote circulating in self-help books and chain emails since the late twentieth century. It has no ancient source.
Last words
Later account by witnesses
«"Crito, we owe a cock to Asclepius. Pay it and do not neglect it."»ὦ Κρίτων, ἔφη, τῷ Ἀσκληπιῷ ὀφείλομεν ἀλεκτρυόνα· ἀλλὰ ἀπόδοτε καὶ μὴ ἀμελήσητε.
Plato, Phaedo 118a. According to the narrator, Phaedo of Elis, he spoke them when the chill of the poison had reached his abdomen: he uncovered his face and said these words, "which were his last". Crito answered that it would be done and asked whether he had anything else to say; Socrates no longer replied. The testimony is literary and second-hand—Plato states in the same dialogue (59b) that he was ill and absent—hence its classification as a witness account transmitted by another. The Greek verb is plural, "we owe": Jowett translates "I owe", Azcárate "debemos un gallo a Esculapio". Asclepius was the god of healing, to whom a cock was offered after recovery. The sentence has been interpreted in many ways: Nietzsche saw in it the confession that life is a disease; Georges Dumézil (1984), thanks for the cure of a false opinion; others, an outstanding vow for Plato's illness or a simple act of piety. Xenophon transmits no last words.

Ask
What their work answers
Twelve great human questions and what their texts allow us to answer, with references. We never put words in their mouth.
What is the Absolute? Does God exist?
A god who entrusts him with a mission and warns him by a sign
A personal GodStated explicitly
Socrates wrote nothing; his relation to the divine is known through Plato and Xenophon, who agree on the essentials. In Plato's Apology he speaks of “the god” of Delphi as someone who has assigned him a post in the city and whom he will obey rather than the Athenians, and he describes a divine sign, a voice that since childhood turns him away from what he should not do. Xenophon, in the Memorabilia, attributes to him an argument from design: eyes, eyelids or affection for offspring show the work of a wise craftsman who loves living beings, and the gods care for humans and see everything. It is a personal dealing with the divine, though Socrates avoids speculating about its nature.
Compare this question with other teachersWho am I? Is there a true self?
What we are is the soul, and caring for it matters above all
A created, immortal soulInferred from their doctrine
In Plato's Apology Socrates sums up his life in an exhortation: not to care for the body or for wealth before the soul, so that it may become as good as possible. The Alcibiades I, of disputed authenticity, draws the conclusion that the human being is his soul, and the Delphic command to know oneself becomes a lifelong task. On immortality, the Socrates of the Apology is cautious and leaves two possibilities open; the arguments of the Phaedo are already Plato's elaboration. Xenophon, for his part, attributes to him the idea that the soul is what in the human shares in the divine. The core attributable to Socrates is that the true self is the soul.
Compare this question with other teachersWhy do we suffer?
Nobody does wrong knowingly: evil is ignorance and harms the soul
Ignorance of what we areInferred from their doctrine
Plato's dialogues attribute to Socrates two theses that together answer the question. First: no one errs willingly; whoever does wrong does so because he takes for good what is not, so that evil is a form of ignorance. Second: the greatest harm is not to suffer injustice but to commit it, because it spoils the only thing that matters, the soul; hence he would rather suffer it than commit it. Thus his reproach to the Athenians in the Apology: they care for wealth, fame and honours and not for the soul or for truth. The suffering that truly counts arises from not knowing oneself and confusing the goods of the body with one's own good.
Compare this question with other teachersWhat happens after death?
Either a dreamless sleep or a journey: in either case, not an evil
Silence or reserveStated explicitly
In Plato's Apology, already condemned, Socrates reasons that fearing death is thinking one knows what one does not know. He proposes two possibilities: either death is being nothing and feeling nothing, like a dreamless sleep, which would be a gain; or it is a migration of the soul to another place, where he could converse with poets and heroes of the past, which would be an immense good. To the good man, he concludes, no evil befalls in life or after death. His last words to the court leave the question open: who goes to the better lot, nobody knows but the god. The proofs of immortality in the Phaedo are already Plato's.
Compare this question with other teachersHow is liberation or salvation attained?
Examining oneself and others: an unexamined life is not worth living
Through direct knowledgeStated explicitly
Socrates promises no salvation, but his whole life is a method for making the soul better. In Plato's Apology he says that the greatest good for a man is to converse every day about virtue and to examine himself and others, and that an unexamined life is not worth living. The instrument is refutation: questioning until the interlocutor discovers that he does not know what he thought he knew, the first step to truly seeking it. If virtue is knowledge, as Aristotle attributes to him, knowing oneself — in the Delphic sense — is the way to become good. His own death, accepted without committing injustice, appears in the dialogues as proof of that freedom.
Compare this question with other teachersIs a teacher necessary?
He does not teach: like a midwife, he delivers what the other carries
The teacher is withinStated explicitly
Plato's Socrates rejects the title of teacher: in the Apology he states that he has never been anyone's teacher nor charged for conversation. In the Theaetetus he describes himself as a midwife: barren of wisdom himself, he helps others give birth to what they carried within and to tell whether it is true or false offspring; what they find they learn not from him but from themselves. His own guidance was inner: a divine sign that turned him away from certain actions. The Meno adds the Platonic theory of recollection, by which seeking and learning are remembering. The outer teacher only asks; truth lies in the soul of the seeker.
Compare this question with other teachersIs the world real?
A world arranged by provident gods, though physics does not occupy him
A good and real creationInferred from their doctrine
The sources agree that Socrates turned away from the investigation of nature. Aristotle states that he dealt with moral questions and not with nature as a whole; Xenophon says he did not discuss how the cosmos came about and considered those who did so foolish. In Plato's Apology he denies knowing anything of what lies beneath the earth or in the sky. But when he speaks of the world he does so in terms of providence: in the Memorabilia he argues that the arrangement of the organs and the beauty of the universe reveal a wise craftsman who cares for living beings, and that the gods have ordered the cosmos for the benefit of humans.
Compare this question with other teachersWhat is love?
He claims to know only love: the desire that improves the beloved
Longing and unionInferred from their doctrine
The man who claimed to know nothing declared himself expert in one thing alone: love. So Plato has him say in the Symposium and the Lysis. In the Symposium Socrates sets out what, he says, Diotima taught him: Eros is the desire to possess the good for ever and to beget in beauty, and it leads by degrees from beautiful bodies to Beauty itself. The Alcibiades of Aeschines of Sphettus, another Socratic, presents his love for the young man as a force that, by divine gift, could make him better without teaching him anything. Xenophon adds conversations on friendship. Socratic love is longing for the good that raises both lover and beloved.
Compare this question with other teachersAre we free, or is everything determined?
The god assigned him a post, and he answers for how he holds it
Destiny and responsibilityInferred from their doctrine
Socrates does not discuss the theoretical problem of freedom, but his life, as Plato and Xenophon tell it, is ordered by a charge. In the Apology he interprets the Delphic oracle as a mission: the god has set him beside the city like a gadfly, and abandoning that post for fear of death would be like deserting in battle. The divine sign turns him away from certain actions and, significantly, did not stop him on the day of the trial. At the same time, responsibility is fully his: in the Crito he chooses not to flee because committing injustice is never permitted. The thesis that nobody errs willingly, however, complicates any reading in terms of free will.
Compare this question with other teachersWhy meditate or pray?
Asking the gods for the good, unspecified, and to be beautiful within
Ritual and self-cultivationStated explicitly
The sources show a Socrates pious in the ways of his city. Xenophon relates that he sacrificed at home and at the public altars, consulted divination and asked the gods simply for good things, since they know best what is fitting; modest sacrifices from someone with little please them no less than great ones. In Plato's Phaedrus, at the end of the conversation, he prays to Pan and the gods of the place to grant him to be beautiful within and that what is outside be in friendship with what is within. Plato also relates that at Potidaea he stood absorbed in thought from dawn to the following dawn.
Compare this question with other teachersCan reason know the ultimate?
He knows he does not know: he tests the god's word by reason
Faith and reason help each otherStated explicitly
Plato's Apology relates how Socrates received the reply of the Delphic oracle — no one was wiser than he — and, instead of simply accepting it, set out to examine it by questioning politicians, poets and craftsmen. He concluded that his wisdom lay in not thinking he knew what he did not know, and that human wisdom is worth little or nothing: the truly wise one is the god. Reason, exercised in dialogue, does not reach a final science of the ultimate, but it purges false opinions and guides life; divine signs and dreams complete that limited knowledge. Aristotle credits him with the search for universal definitions and inductive arguments.
Compare this question with other teachersWithdraw from the world or transform it?
True politics is making the citizens' souls better
The revolution is innerStated explicitly
Socrates did not withdraw from Athens: he spent his life in the agora, served as a hoplite and fulfilled his public offices, opposing the majority and the Thirty when justice required it. But, according to Plato's Apology, he abstained from active politics because his divine sign prevented him and because whoever truly fights for justice does not survive long in it. His task was another: to urge each citizen, in private, to care for the soul before wealth. In the Gorgias he claims to be one of the few Athenians practising the true political art, because he seeks his fellow citizens' good and not their pleasure. Changing the city begins with changing souls.

Anecdotes and stories
Anecdotes and stories
Testimonyantes del 431 a. C. (incierto)
The Delphic oracle
Origin of the story: Plato, Apology 20e–23b, where Socrates calls Chaerephon's brother as witness, Chaerephon being dead. Xenophon (Apology 14) gives a different version: the oracle supposedly said no one was more free, just or sensible than Socrates. Some scholars doubt the consultation took place; others accept it because it appears in a speech delivered before hundreds of Athenians.
Testimony432–424 a. C.
Potidaea and Delium
Origin of the story: Plato, Symposium 219e–221c; the Laches (181b) confirms the conduct at Delium through the general Laches. It is a literary testimony in a character's mouth, but it agrees with the Apology (28e) on the three campaigns. The Aristophanes quotation comes from the Clouds (362).
Documented406–404 a. C.
The Arginusae generals and Leon of Salamis
Origin of the story: Plato, Apology 32b–e; Xenophon, Hellenica I 7.14–15 and Memorabilia I 1.18 and IV 4.2–3. It is one of the few episodes in Socrates' life attested by two independent authors and by a historian narrating the events apart from Socrates.
Disputed423 a. C.
Socrates stands up in the theatre
Origin of the story: Aelian, Varia Historia II 13 (2nd–3rd century CE). There is no contemporary testimony. Plutarch (On the Education of Children 14) attributes a similar reaction to Socrates when mocked by comedy. The story of a bribe to Aristophanes is incompatible with the chronology.

Unverifiables. V a. C. (tradicional)
Xanthippe and the water
Origin of the story: Diogenes Laertius II 36–37 (3rd century CE); the image of the difficult wife is already in Xenophon, Symposium 2.10, where Antisthenes calls her "the most intolerable of women", and Memorabilia II 2. The bucket scene appears only in late sources and belongs to a repertoire of jokes about philosophers; it inspired many Baroque paintings.
Testimony401 a. C.
Xenophon asks for advice
Origin of the story: Xenophon, Anabasis III 1.4–7, in which the author himself narrates the episode. It is the only surviving autobiographical testimony of a private conversation with Socrates.

Connections
Connections
Influences, discipleships and affinities. Documented relations are distinguished from similarities identified by analysis.
Teacher of
Plato frequented Socrates in his youth, attended the trial (Apology 34a, 38b) and made him the protagonist of almost all his dialogues.
Documented relation
Teacher of
Jenofonte
A pupil in his youth; he wrote the Memorabilia, the Apology, the Symposium and the Oeconomicus, and recounts in the Anabasis how he asked him for advice.
Documented relation
Teacher of
Antístenes
A follower of Socrates present at his death (Phaedo 59b); founder of the tradition that would lead to Cynicism.
Documented relation
Contemporary of
Aristófanes
He caricatured him in the Clouds (423 BCE); Plato seats them together in the Symposium.
Documented relation
Influenced
He never knew him, but in the Metaphysics credits him with induction and universal definition and discusses his moral intellectualism in the Nicomachean Ethics.
Documented relation
Influenced
A pupil of Antisthenes according to Diogenes Laertius (VI 21); Plato allegedly called him "a Socrates gone mad" (VI 54).
Documented relation
Influenced
According to Diogenes Laertius (VII 2–3), he became a philosopher after reading the second book of Xenophon's Memorabilia in Athens.
Documented relation
Influenced
The Discourses recorded by Arrian hold up Socrates as the constant model of the philosophical life.
Documented relation
Met
Plato narrates a meeting between a very young Socrates and the aged Parmenides in the dialogue Parmenides; it is almost certainly a literary fiction.
Similarity identified by analysis
Ideas akin to
The speakers of the Phaedo, Simmias and Cebes, had frequented the Pythagorean Philolaus; the immortality of the soul and the philosophical life as purification bring Plato's Socrates close to the Pythagorean tradition.
Similarity identified by analysis
Ideas akin to
Oral teachers known through their disciples, centred on virtue and self-examination; Karl Jaspers grouped them among the "paradigmatic individuals".
Similarity identified by analysis
Ideas akin to
Neither wrote anything, both were executed by the authority of their city and their figure reaches us through disciples who disagree; the comparison has been a commonplace since the Christian apologists.
