Age of Pericles

 

Golden Age after defeat of Persia

Built Parthenon

Instigated direct democracy

 

Peloponnesian War

Sparta surrounded Athens. Pericles knew that the Athenian army could not beat the Spartans, so they remained inside the protected walls of Athens. Plague broke out. Pericles died.  After 25 years of war, the Spartans destroyed the Athenian navy and Athens surrendered.  The city walls were torn down.  The Athenians wondered why they lost and a period of great self-examination began for Athens.

 

In this context Socrates and Plato taught.

 

(Plato’s cave)

 

Socrates thought that questions of truth were directly related to how one should live one’s life and how the polis was to be run. 

 

What is reality like?  What is true?  Is everything one unchanging eternal whole, like Zeno argued, or is everything made up of atoms constantly moving and changing?

 

His first task was to answer the Sophists and Skeptics.  What can we know for certain? This is different from facts (there is a desk in my room); it means those things that are eternally true and never change.

The model—Pythagoras. 

 

The same model of truth. That which is true is relational and proportional. 

 

Man must have a balance in life, the passions (Hubris: remember the anger of Achilles) must be controlled by reason.  This is the proper relation within human beings, to avoid Hubris (self pride, arrogance, passions).

 

The Pythagorean theorem plays right into this idea of knowledge.  Recall that a true rectilinear triangle is not something physical or drawn, but something substantiated by a mathematical relationship, a relational statement. It is immutable.  We can distinguish between the drawn triangle and the true form of the triangle.  True form suffers no change and should be the proper focus of the soul.

 

This means that true and eternal things are not found in the physical world, but in the world of forms.

 

 

 

 

 

Theory of the forms

The ideal                                  The particular

Horse                                       Black Beauty

Perfect                                     imperfect copy

Eternal                                      changing

 

We become wise by thinking about the forms; they are more important than the material world.  This means that being able to think properly is more important than experience; experience only gives us information about the particular, imperfect things, not about truth itself.  Thus experience is not that important.

 

What is to be avoided at all costs is a slavish adherence to experience, as if experience can lead us to perfect truth.  Experiences flood in by the thousands each day, yet the world is full of villains and fools, all of whom have had experience.  You cannot make a distinction between the wise and the foolish based on who has had more experience.  If this is true, then the fact that three people constitute more collective experience than one counts for nothing.  Self-deception is not eliminated by multiplying the number of those deceived.  “It is not majorities that establish truth.  It cannot be majorities that cut the path to knowledge.”

 

In the context of the defeat of Athens by Sparta: Plato and Socrates both said that the problem of truth must be dealt with before we can determine how to live life and how the polis should be run.  Plato’s theory of the forms answered the problem of truth.  If experience does not lead to truth, majorities mean nothing.  Democracy cannot work.  What was the weakness of Athens that allowed them to be defeated by Sparta?  The assumptions of democracy.
