Greek Philosopher. Born in 470 BC, he is known as the founder of Ethics and Philosophy. For him philosophical research was a relentless examination of ourselves. He thought that only those who know do not of knowing, wants to know the Truth. His search method was the dialogue, and his doctrine can be summarized in the aphorism “Know thyself”. In 399 BC, he was accused of corrupting the morality of athenian youth because of his public dialogues, was tried and sentenced to death. According to Plato, he accepted serenely his destiny.  (bio by: Lucy Caldarelli)
