Existentialist Philosopher-Socrates

Socrates was a Greek philosopher in the 469 BC – 399 BC. He was a teacher to Plato,  Xenophon, Aristotle, and Aristophanes. He was a critic of democracy and he clashed with the politics that was current in his time in Athens. He made several offences that led him to his death trial such as praising Sparta, archrival to Athens, directly and indirectly and holding a position as a social and moral critic. Rather than upholding a status quo and accepting the development of what he perceived as immorality within his region, Socrates questioned the collective notion of "might makes right" that he felt was common in Greece during this period. His attempts to improve the Athenians' sense of justice may have been the source of his execution.
He came up with dialectic analysis where to solve a problem, he would break it down into a series of questions which gradually distill the answer a person seeks. This was used to test scientific hypothesies as well as in politics, philosophy and ethics.
Socrates is notorious for asking questions but never answering them, claiming to lack the wisdom to answer the questions he asked of others. He believes that people should be worried about the "wellfare of their souls instead of being concerned with their families, careers, and political responsibilities.
Socrates' belief in the immortality of the soul, and his conviction that the gods had singled him out as a divine emissary seemed to provoke, if not ridicule, at least annoyance. Socrates also questioned the Sophistic doctrine that virtue can be taught. He said that successful fathers did not produce sons of their own quality. Socrates argued that moral excellence was more a matter of divine bequest than parental nurture. This belief may have contributed to his lack of anxiety about the future of his own sons.
