In his use of critical reasoning, by his unwavering commitment to truth, and through the vivid example of his own life, fifth-century Athenian Socrates set the standard for all subsequent Western philosophy. Since he left no literary legacy of his own, we are dependent upon contemporary writers like Aristophanes and Xenophon for our information about his life and work.

As a pupil of Archelaus during his youth, Socrates showed a great deal of interest in the scientific theories of Anaxagoras, but he later abandoned inquiries into the physical world for a dedicated investigation of the development of moral character. Having served with some distinction as a soldier at Delium and Amphipolis during the Peloponnesian War, Socrates dabbled in the political turmoil that consumed Athens after the War, then retired from active life to work as a stonemason and to raise his children with his wife, Xanthippe. After inheriting a modest fortune from his father, the sculptor Sophroniscus, Socrates used his marginal financial independence as an opportunity to give full-time attention to inventing the practice of philosophical dialogue.

For the rest of his life, Socrates devoted himself to free-wheeling discussion with the aristocratic young citizens of Athens, insistently questioning their unwarranted confidence in the truth of popular opinions, even though he often offered them no clear alternative teaching.
Unlike the professional Sophists of the time, Socrates pointedly declined to accept payment for his work with students, but despite (or, perhaps, because) of this lofty disdain for material success, many of them were fanatically loyal to him. Their parents, however, were often displeased with his influence on their offspring, and his earlier association with opponents of the democratic regime had already made him a controversial political figure.
Although the amnesty of 405 forestalled direct prosecution for his political activities, an Athenian jury found other charges—corrupting the youth and interfering with the religion of the city—upon which to convict Socrates, and they sentenced him to death in 399 B.C.E.
Accepting this outcome with remarkable grace, Socrates drank hemlock and died in the company of his friends and disciples.( Rhodes dodecanese guide - directory greece rhodos kos e.t.c )
