 It is not at all clear whether there are one or more philosophical affinities among this group of six dialogues—that is, whether the philosophy they contain is sharply different from that of all of the other dialogues. Plato does nothing to encourage the reader to view these works as a distinctive and separate component of his thinking. On the contrary, he links Sophist with Theaetetus (the conversations they present have a largely overlapping cast of characters, and take place on successive days) no less than Sophist and Statesman. Sophist contains, in its opening pages, a reference to the conversation of Parmenides—and perhaps Plato is thus signaling to his readers that they should bring to bear on Sophist the lessons that are to be drawn from Parmenides. Similarly, Timaeus opens with a reminder of some of the principal ethical and political doctrines of Republic. It could be argued, of course, that when one looks beyond these stage-setting devices, one finds significant philosophical changes in the six late dialogues, setting this group off from all that preceded them. But there is no consensus that they should be read in this way. Resolving this issue requires intensive study of the content of Plato’s works. So, although it is widely accepted that the six dialogues mentioned above belong to Plato’s latest period, there is, as yet, no agreement among students of Plato that these six form a distinctive stage in his philosophical development.
