Because of his political associations with an earlier regime, the Athenian democracy put Socrates on trial, charging him with undermining state religion and corrupting young people. The speech he offered in his own defense, as reported in Plato's Απολογημα (Apology), provides us with many reminders of the central features of Socrates's approach to philosophy and its relation to practical life.
Ironic Modesty:
Explaining his mission as a philosopher, Socrates reports an oracular message telling him that "No one is wiser than you." (Apology 21a) He then proceeds through a series of ironic descriptions of his efforts to disprove the oracle by conversing with notable Athenians who must surely be wiser. In each case, however, Socrates concludes that he has a kind of wisdom that each of them lacks: namely, an open awareness of his own ignorance.
Questioning Habit:
The goal of Socratic interrogation, then, is to help individuals to achieve genuine self-knowledge, even if it often turns out to be negative in character. As his cross-examination of Meletus shows, Socrates means to turn the methods of the Sophists inside-out, using logical nit-picking to expose (rather than to create) illusions about reality. If the method rarely succeeds with interlocutors, it can nevertheless be effectively internalized as a dialectical mode of reasoning in an effort to understand everything.
Devotion to Truth:
Even after he has been convicted by the jury, Socrates declines to abandon his pursuit of the truth in all matters. Refusing to accept exile from Athens or a commitment to silence as his penalty, he maintains that public discussion of the great issues of life and virtue is a necessary part of any valuable human life. "The unexamined life is not worth living." (Apology 38a) Socrates would rather die than give up philosophy, and the jury seems happy to grant him that wish.
Dispassionate Reason:
Even when the jury has sentenced him to death, Socrates calmly delivers his final public words, a speculation about what the future holds. Disclaiming any certainty about the fate of a human being after death, he nevertheless expresses a continued confidence in the power of reason, which he has exhibited (while the jury has not). Who really wins will remain unclear.
Plato's dramatic picture of a man willing to face death rather than abandoning his commitment to philosophical inquiry offers up Socrates as a model for all future philosophers. Perhaps few of us are presented with the same stark choice between philosophy and death, but all of us are daily faced with opportunities to decide between convenient conventionality and our devotion to truth and reason. How we choose determines whether we, like Socrates, deserve to call our lives philosophical.
