Abstract

In the first third of the Theatetus, Socrates develops a Protagorean-Heraclitean account of Theatetus' thesis that knowledge is perception. It is natural to think that Plato's presentation of the views reveals that the theories of Theaetetus, Protagoras and Heraclitus are linked by implication . I show that this position does not take sufficient account of the explicatory relations between the concepts of the theories. According proper space to explication not only allows one to be clearer about the structure of the transitions but clarifies many of the puzzles surrounding that part of the dialogue
