query: What years did Socrates live?
passage: Socrates
The year of birth of Socrates stated is an assumed date,[50] or estimate,[51] given the fact of the dating of anything in ancient history in part being sometimes reliant on argument stemming from the inexact period floruit of individuals.[52] Diogenes Laërtius stated Socrates birth date was "the sixth day of Thargelion, the day when the Athenians purify the city".[53] Contemporaneous sources state, he was born not very much later than sometime after the year 471,[54] his date of birth is within the period of years ranging 470 to 469BC,[55] or within a range 469 to 468BC (corresponding to the fourth year of the 77th Olympiad).[36][37]
passage: History of Western civilization before AD 500
Ancient Greek philosophy arose in the 6th century BC and continued through the Hellenistic period, at which point Ancient Greece was incorporated into the Roman Empire. It dealt with a wide variety of subjects, including political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric, and aesthetics. Plato was a Classical Greek philosopher, mathematician and writer of philosophical dialogues. He was the founder of the Academy in Athens which was the first institution of higher learning in the Western world. Inspired by the admonition of his mentor, Socrates, prior to his unjust execution that "the unexamined life is not worth living", Plato and his student, the political scientist Aristotle, helped lay the foundations of Western philosophy and science. Plato's sophistication as a writer is evident in his Socratic dialogues.
