Values • Everyone will have a personal answer to this question that is unique to their situation. • They will refer to specific things they care about. • This is called subjective value. These things have subjective, or personal, importance. • (Opposite –universal or “Objective” value) • For Socrates, one universal value: TRUTH • This value was worth dying for…

The Trial and Death of Socrates • Socrates compared himself to a “Horse-fly” on society’s butt • He managed to piss off lots of powerful people with his constant questions • Eventually he was arrested on 2 charges:1. Impiety (for his “strange” view on the Gods)2. Corrupting the Youth (for encouraging the young not to fight in Athens’s constant wars over territory)
Death of Socrates • “I would rather die having spoken in my manner, than speak in your manner and live. …The difficulty, my friends, is not in avoiding death, but in avoiding unrighteousness; for that runs deeper than death…” • Quoted from Plato’s Book on the trial, Apology, 38e-39a
Plato: Everyone is Stupid • Socrates had a student, Plato, who was greatly upset by his execution.

Allegory (Myth) of the CAVE • 1 PEOPLE=2 CAVE=3 CHAINS=4 SHADOWS=5 ESCAPEE=6 OUTSIDE=7 SUN=8 REJECTION= -Plato’s famous fable about Truth -Come down on the floor – demonstration -Video: http://www.youtube.com/watch?v=LTWwY8Ok5I0-After: Each element of the story is symbolic. Figure out the symbolism, and the message of the myth.
Summary of the Myth • Plato sees that things in the material world do not last, but decay over time (impermanence) • Ideas and Concepts, however, are Eternal • He reasons that Ideas represent a Higher Realm than the world of sensory experience • Trust thought, not your senses • Truth is not a physical thing, but an Idea (Form)-http://www.youtube.com/watch?v=c6KVHMU3gb8 • What kind of epistemology is this? • Why are its (scary) implications?
What is our Reality isn’t REAL? • If there are “other Realms” that we lack the faculties to perceive, what else don’t we know? • If our senses deceive us, how can we be sure our experience is the Truth? • These kind of questions lead to an epistemology of doubt: SKEPTICISM • Various “Skepticisms” about Reality
What if we’re Dreaming? • Anyone who’s had a vivid dream knows it feels “Real” to your mind until you wake • It is impossible to prove this is not a dream(How would you prove it 100%?) • If this was a dream, what would you “wake up into?”“ Is all that we see or seemBut a dream within a dream? “ – Edgar Allan Poe
What if we’re Prisoners? • French Philosopher Rene Descartes asked:What if what I think of as the Outside World is an illusion created by an Evil Demon to trick me? • He didn’t really think this: he was testing the limits of knowledge. He was shocked he couldn’t disprove it! • Descartes finally decided: “Cogito, ergo Sum.” • This means, “I think, therefore I exist.” • Because he could experience his own thoughts from “within,” he was convinced his mind was real, but not necessarily his body or the Outside World!
