 We are of course familiar with the dialogue form through our acquaintance with the literary genre of drama. But Plato’s dialogues do not try to create a fictional world for the purposes of telling a story, as many literary dramas do; nor do they invoke an earlier mythical realm, like the creations of the great Greek tragedians Aeschylus, Sophocles, and Euripides. Nor are they all presented in the form of a drama: in many of them, a single speaker narrates events in which he participated. They are philosophical discussions—“debates” would, in some cases, also be an appropriate word—among a small number of interlocutors, many of whom can be identified as real historical figures (see Nails 2002); and often they begin with a depiction of the setting of the discussion—a visit to a prison, a wealthy man’s house, a celebration over drinks, a religious festival, a visit to the gymnasium, a stroll outside the city’s wall, a long walk on a hot day. As a group, they form vivid portraits of a social world, and are not purely intellectual exchanges between characterless and socially unmarked speakers. (At any rate, that is true of a large number of Plato’s interlocutors. However, it must be added that in some of his works the speakers display little or no character. See, for example, Sophist and Statesman—dialogues in which a visitor from the town of Elea in Southern Italy leads the discussion; and Laws, a discussion between an unnamed Athenian and two named fictional characters, one from Crete and the other from Sparta.) In many of his dialogues (though not all), Plato is not only attempting to draw his readers into a discussion, but is also commenting on the social milieu that he is depicting, and criticizing the character and ways of life of his interlocutors (see Blondell 2002). Some of the dialogues that most evidently fall into this category are Protagoras, Gorgias, Hippias Major, Euthydemus, and Symposium.
