Abstract

In this work I argue that the Theaetetus is a dialogue about the relation between the concept of reason, understood as a kind of power of the mind, and perception, viewed as an unconscious process of the body. In the first chapter I examine Platos analysis of Protagorean epistemology. I try to show that in this section Plato is not arguing his own view about the sensible world. He is, rather, explaining and criticizing the fundamental principles of the protagorean epistemology. At the end of this section Plato explains the distinction between reason and perception. In my analysis of the second part, I argue that the mass of arguments of this section formulates a platonic thesis about the essence of knowledge. Finally, in my commentary of the third definition, I examine Dreams concept of logos and the meaning of the thesis that the elements are perceivable. (AU)
