True Belief and Cognition-An Interpretation of Theaetetus 208c4-209d3

Abstract

In the last passage of the Theaetetus (208c6-210b3), Socrates tries to define knowledge of an object as true belief with the logos which means the description distinguishing it from any other object. At first half of this passage (208c4-209d3), Plato put in question how to specify an object as what it is without having its logos.
In my view of this paper, Plato explains a specification of an object in one's belief context. If one has a true belief about an object, he can be directly conscious of a distinction in his belief between it and any other object without having its logos. His cognitive experience is based on the dintinction, which he has obtained in his memory and cannot be known to others.
