Plato 
Apology [PDF ebook] 

This historically renowned oration was presented by Socrates in his own defense after he had been formally accused of corrupting the youth of Athens. It is not an apology in the traditional sense of expressing remorse for one’s actions; rather, Socrates’ Apology (recorded by his faithful student and protege Plato) is a succinct and compelling defense of the brilliant philosopher’s worldview, lifestyle, and teaching methods. A rewarding read for fans of philosophy and supporters of intellectual freedom.
