Man lives amidst shadows. He creates opinions about things that he is not even sure if they exist. And even these things are not entirely real. The scientist can transcend the flawed world of the senses — of the things as they appear to us — and elaborate hypotheses about reality. But only the philosopher comes to see the light and, from it, he can see things as they really are. This is the Platonic theory about the world, a fascinating blend of theory of knowledge and metaphysics.
Although Leonard Peikoff (and Objectivism) disagrees entirely with Plato, he admits the genius of the philosopher. Plato was the first to gather all the “suggestions” that had been produced by the pre-Socratics and the sophists, in addition to all the teachings of Socrates in a coherent whole. In doing so, he created philosophy as it is, for better or for worse.
