Abstract
In recent years considerable attention has been focused on the question whether Plato ever uses arguments he knows to be sophistical, especially whether he puts such arguments into the mouth of Socrates. Though differing views have been held, at the present time the majority of scholars seem to believe that Plato does not. Though I disagree with this position, I will not attack it directly in this paper. Instead I will discuss what I take to be an important preliminary matter, establishing criteria that can be employed in order to assess the claim that one of Plato's characters does or does not argue sophistically. Since the case of Socrates is by far the most important, I will limit discussion here to the question whether Socrates ever uses sophistry
