Abstract
It is a commonplace to sum up Plato's dialectical method under the formula logon didonai, which means to account for one's belief. The expression along with its genuine meaning seems to have originated at Greek courts of law, and Plato's Socrates, having adopted this formula to describe his philosophical method, seems to be the best advocate of the idea that to know means to be able to render an account. This paper aims to give a critical discussion of these traditional views. First, there is no hint of any offspring of the expression logon didonai at Greek courts of law. Second, in pre-Socratic contexts the expression had not one but several meanings. And third, Plato, through the voice of Socrates, criticizes the unclear meaning of this expression in epistemological contexts.
