 Furthermore, the dialogues have certain characteristics that are most easily explained by supposing that Plato is using them as vehicles for inducing his readers to become convinced (or more convinced than they already are) of certain propositions—for example, that there are forms, that the soul is not corporeal, that knowledge can be acquired only by means of a study of the forms, and so on. Why, after all, did Plato write so many works (for example: Phaedo, Symposium, Republic, Phaedrus, Theaetetus, Sophist, Statesman, Timaeus, Philebus, Laws) in which one character dominates the conversation (often, but not always, Socrates) and convinces the other speakers (at times, after encountering initial resistance) that they should accept or reject certain conclusions, on the basis of the arguments presented? The only plausible way of answering that question is to say that these dialogues were intended by Plato to be devices by which he might induce the audience for which they are intended to reflect on and accept the arguments and conclusions offered by his principal interlocutor. (It is noteworthy that in Laws, the principal speaker—an unnamed visitor from Athens—proposes that laws should be accompanied by “preludes” in which their philosophical basis is given as full an explanation as possible. The educative value of written texts is thus explicitly acknowledged by Plato’s dominant speaker. If preludes can educate a whole citizenry that is prepared to learn from them, then surely Plato thinks that other sorts of written texts—for example, his own dialogues—can also serve an educative function.)
