ONE:The principal object of Plato��s negative criticism had been to emphasise the distinction between reality and appearance in the world without, between sense, or imagination, and reason in the human soul. True to the mediatorial spirit of Greek thought, his object now was to bridge over the seemingly impassable gulf. We must not be understood to say that these two distinct, and to some extent contrasted, tendencies correspond to two definitely divided periods of his life. It is evident that the tasks of dissection and reconstruction were often carried on conjointly, and represented two aspects of an indivisible process. But on the whole there is good reason to believe that Plato, like other men, was more inclined to pull to pieces in his youth and to build up in his later days. We are, therefore, disposed to agree with those critics who assign both the Phaedrus and the Symposium to a comparatively advanced stage of Platonic speculation. It is less easy to decide which of the two was composed first, for there seems to be a greater maturity of thought in the one and of style in the other. For our purposes it will be most convenient to consider them together.
