The present thesis is an attempt to give a definition of philosophy by looking at the philosopher's definition of sophistry. My main goal has been to understand the conceptual framework in which sophistry and philosophy ara positioned as polar concepts in order to question if there can be a theorethical basis for demarcating philosohy from false philosophy. I tried to focus on two important characters in Ancient Greece. The first one is Plato, the first philosopher, and the other is Gorgias, the father of sophistry. The comparison between their thoughts is intended to see how the philosopher has constructed himself as the opposite of the sophist.
