Ancient Greek Philosophers

1. Ancient Greek Philosophers

2. Socrates • 470-399BC • Laid the foundation for Western philosophy • Became known as the “wisest man in all of Greece” • Most of what is known about Socrates is derived from information of different sources. • Plato • Xenophone • Aristophanes • Aristotle

3. Socrates • Socrates was critical of Athenian democracy, and preached to his students, that a monarchy was preferable. • He praised the laws and government of Sparta • When his students began betraying Athens to Sparta, this became a catalyst for the trial against Socrates.

4. Plato’s Apology • In the defense of Socrates, contained in the Apology by Plato, Socrates questioned the men of Athens about their knowledge of good, beauty, and virtue. Finding they knew nothing and yet believed themselves to know much, Socrates came to the conclusion that he was only wise only in so far as he knew nothing. This made the prominent Athenians look foolish, turning them against him. • He was found guilty of corrupting the youth, inventing new deities (heresy), and disbelieving in the divine ( atheism).

5. Death of Socrates • He was sentenced to die by drinking a silver goblet of hemlock. • Socrates turned the pleas of his disciples to attempt an escape from prison. • According to the Phaedo, Socrates had a calm death. • According to Plato and Xenophone, Socrates had an opportunity to escape, as his followers were able to bribe the guards. But Socrates did not want to leave Athens.

6. The Death of Socrates • Socrates refused to escape for several reasons: • 1. He believed that such a fight would indicate a fear of death, which he believed that no true philosopher has. • 2. Even if he did leave, he, and his teaching would not fare better in another country. • 3. Having knowingly agreed to live under the city’s laws, he implicitly subjected himself to the possibility of being accused of crimes by its citizens and judged guilty by its jury. • So…at age 70 Socrates was put to death.

7. Socratic Method • Answering a question with a question • A method of inquiry, known as the Socratic method was probably his most important contribution. • It allows for the examination of key moral concepts such as Good and Justice. • It was first described by Plato in the Socratic Dialogues. • He is believed to be the father of political philosophy and ethics or moral philosophy.

8. Socrates beliefs • “Wisdom is limited to an awareness of ones own ignorance” • He believed that the best way for people to live was to focus on self-development, rather than the pursuit of material wealth. • Concentrate more on friendships and a sense of true community. • He stressed that “virtue was the most valuable of all possessions; the ideal life was spent in search of the Good. Truth lies beneath the shadows of existence, and that it is the job of the philosopher to show the rest how little they really know.”

9. Beliefs continued: • To truly be good and not just act with “right opinion”; one must come to know the unchanging Good in itself. • “Ideals belong in a world that only the wise amn can understand” • He also discussed reincarnation and the mystery religions • He objected to democracy

Governing class- The rulers • He believed that a person with sound reason and wisdom should govern- Therefore it should be a “philosopher king”, that is someone “who loves the sight of truth.” • He also addresses the education system in The Republic, therefore producing the philosopher king.

16. The Lyceum • In 336BC, Aristotle opened his own school The Lyceum. • This is after he tutored Alexander the Great • He believed that philosophy was also a science of that which is “actual” • He thought that in order to become “good”, one could not simply study what virtue is; one must actually be virtuous.

18. Diogenes- “The Cynic” • It was said of Diogenes that throughout his life he “searched with a lantern in the daylight for an honest man.” And though Diogenes apparently did not find an honest man, he had, in the process, “exposed the vanity and selfishness of man.” • He was a pupil of Antisthenes who founded the cynics. • Cynics held contempt for ease, wealth and the enjoyments of life. • Diogenes took this to heart- his clothing was the coarsest- his food the plainest- and his bed was the bare ground.

19. Cynicism • Like Socrates, the Cynics believed that VIRTUE was the greatest good. • The purpose of a cynic was to expose the follies of their times, as well as the timeless foibles of humankind. • “A cynic is a spy who aims to discover what things are friendly or hostile to man; after making accurate observations, he then comes back and reports the truth.”

I nuzzle the kind, bark at the greedy and bite scoundrels.”

23. Skeptics-Pyrrho • Pyrrho denied practically everything: he believed objective knowledge is impossible to achieve and that one should free oneself from opinions, passions, be calm at mind and soul and totally turn one’s back on the world. • To Pyrrho, life and death was one and the same. • When crossing a street…he never looked around, and if a wagon came against him he did not turn back, constantly being rescued by friends and disciples.
