"The Platonic dialogues illustrate two of Wittgenstein's own theses or assumptions, of which the first is that human discourse, and in particular, philosophical discourse, has no beginning and no end. We are always in medias res. Second, therefore, there are no final or comprehensive discursive constructions, or theories in the sense deprecated by Wittgenstein. But for Plato, contrary to Wittgenstein, there is a top and a bottom to philosophical discourse, and this is represented by the Ideas on the one hand and the doctrine of eros on the other. In more prosaic terms, we are united by our desires, and these in turn are regulated by the natures of the objects of our desire. What one could call ordinary or ordinal discourse is thus defined pragmatically by the intelligibility of desire".
Stanley Rosen, "Leo Strauss And The Possibility of Philosophy".
