 The best way to form a reasonable conjecture about why Plato wrote any given work in the form of a dialogue is to ask: what would be lost, were one to attempt to re-write this work in a way that eliminated the give-and-take of interchange, stripped the characters of their personality and social markers, and transformed the result into something that comes straight from the mouth of its author? This is often a question that will be easy to answer, but the answer might vary greatly from one dialogue to another. In pursuing this strategy, we must not rule out the possibility that some of Plato’s reasons for writing this or that work in the form of a dialogue will also be his reason for doing so in other cases—perhaps some of his reasons, so far as we can guess at them, will be present in all other cases. For example, the use of character and conversation allows an author to enliven his work, to awaken the interest of his readership, and therefore to reach a wider audience. The enormous appeal of Plato’s writings is in part a result of their dramatic composition. Even treatise-like compositions—Timaeus and Laws, for example—improve in readability because of their conversational frame. Furthermore, the dialogue form allows Plato’s evident interest in pedagogical questions (how is it possible to learn? what is the best way to learn? from what sort of person can we learn? what sort of person is in a position to learn?) to be pursued not only in the content of his compositions but also in their form. Even in Laws such questions are not far from Plato’s mind, as he demonstrates, through the dialogue form, how it is possible for the citizens of Athens, Sparta, and Crete to learn from each other by adapting and improving upon each other’s social and political institutions.
