 Of course, there are other more speculative possible ways of explaining why Plato so often makes Socrates his principal speaker. For example, we could say that Plato was trying to undermine the reputation of the historical Socrates by writing a series of works in which a figure called “Socrates” manages to persuade a group of naïve and sycophantic interlocutors to accept absurd conclusions on the basis of sophistries. But anyone who has read some of Plato’s works will quickly recognize the utter implausibility of that alternative way of reading them. Plato could have written into his works clear signals to the reader that the arguments of Socrates do not work, and that his interlocutors are foolish to accept them. But there are many signs in such works as Meno, Phaedo, Republic, and Phaedrus that point in the opposite direction. (And the great admiration Plato feels for Socrates is also evident from his Apology.) The reader is given every encouragement to believe that the reason why Socrates is successful in persuading his interlocutors (on those occasions when he does succeed) is that his arguments are powerful ones. The reader, in other words, is being encouraged by the author to accept those arguments, if not as definitive then at least as highly arresting and deserving of careful and full positive consideration. When we interpret the dialogues in this way, we cannot escape the fact that we are entering into the mind of Plato, and attributing to him, their author, a positive evaluation of the arguments that his speakers present to each other.
