A Short Introduction to Socrates

An excellent short introduction to by far one of the most significant philosophers to have ever lived. One could say, that through Plato and Aristotle and the real flowering of thought that occurred through them, that Socrates was the most important philosophers to have ever lived. He wrote nothing for posterity, but the idea of Socrates, the idea of that gadfly, that person always questioning, down into and out of the most minutiae thought, transcended the times he lived in and really propelled not only his city-state of Athens forward, but impacted the course of western civilization. He lived philosophy in a way that others can only aspire to. 

And all that he knew is that he didn't know anything.
