Despite the fact that Socrates was perhaps the most celebrated thinker of ancient times, we know almost nothing about him as a person. He left no written documents. Those who wrote about him presented their own version of him, not the historical Socrates. Our basic sources of information about his personality and his doctrines are a comedy by Aristophanes (Clouds); Xenophon's 'Socratic' works; and almost every one of Plato's dialogues.

He was born at Athens in 470 B.C. or thereabouts. Though he did not engage actively in politics, he fulfilled whatever political obligations his citizen status or the institution of the lot imposed on him. This meant that he took part in various battles; and that in 406 he served as prytanis - or, as some would have it, chairman of the committee. This was the year of the 'Trial of the Six': the six generals sentenced to death by the People's Assembly for not stopping to pick up survivors after the naval victory at Arginusae. Apparently, not only was Socrates against the death sentence, but he refused to arrest one of the generals when ordered to do so by the Thirty Tyrants. He died in 399 B.C., by poison, having been sentenced to death by a jury under oath.


The accusation as formulated under oath at the preliminary hearing has been preserved entire: Socrates was accused of "impiety" and of "corrupting the young by his teachings". How did he defend himself against this accusation in court? None of our sources can be regarded as a reliable record of the defence speech, even though works survive that purport to give it - the Apology of Plato and that of Xenophon. In any case, Socrates' trial, condemnation, and death made an important contribution to the elevation of the thinker into a symbol.

It is chiefly from Plato's works that we know the content of Socrates' teaching. This is a headache for scholars, since it is impossible to sort out which elements are 'Socratic' and which are 'Platonic'. For sure Socrates never followed a systematic teaching pattern. It was mainly his way of arriving at a conclusion that made him celebrated and that was elevated by his disciples into a method. Socrates himself used to say that he was like a midwife - helping the person who talked with him to himself "give birth" to the answers to his perplexities, by inserting the right questions to extract the answer. Thus his method - the way the student-listener is led to conclusions by means of dialectic (question-and-answer) - was nicknamed "obstetrical". We have Aristotle's word for it that Socrates' contribution to philosophy was the pursuit of the inductive method and the definition of terms. Another element in Socratic teaching was the pursuit of ethical values. These Socrates tried to define with concepts of general validity (in contrast to the Sophists, who believed that ethical rules are inferred from discussion of each new situation). According to Socrates, ethical rules exist and one need only be familiar with them to eb sure to follow them in one's behaviour: to use his phrase, "Nobody [is] of their own volition evil". He supported the necessity of the Delphic prophecy "Know thyself", since he believed that anybody can, with suitable guidance, be led to self-knowledge.
