Plato studied under Socrates and was Aristotles teacher. Together these three Greeks developed the basis of philosophical thinking for the entire Western world. Plato was also a writer, mathematician, and founder of the Academy in Athens, which was the first university in Europe. Philebus is one of Platos more difficult works to interpret. In Philebus the major theme revolves around the doctrine that good resides in thought and mind rather than in pleasure or the body.
