INTRODUCTION.

is no real proof that he ever went to Egypt; and even if he did, he might have known or invented Egyptian traditions before he went there. The late date of the Phaedrus will have to be established by other arguments than these: the maturity of the thought, the perfection of the style, the insight, the relation to the other Platonic Dialogues, seem to contradict the notion that it could have been the work of a youth of twenty or twenty-three years of age. The cosmological notion of the mind as the primum mobile, and the admission of impulse into the immortal nature, also afford grounds for assigning a later date. (Compare Tim., Soph., Laws.) Add to this that the picture of Socrates, though in some lesser particulars,—e.g. his going without sandals, his habit of remaining within the walls, his emphatic declaration that his study is human nature,—an exact resemblance, is in the main the Platonic and not the real Socrates. Can we suppose 'the young man to have told such lies' about his master while he was still alive? Moreover, when two Dialogues are so closely connected as the Phaedrus and Symposium, there is great improbability in supposing that one of them was written at least twenty years after the other. The conclusion seems to be, that the Dialogue was written at some comparatively late but unknown period of Plato's life, after he had deserted the purely Socratic point of view, but before he had entered on the more abstract speculations of the Sophist or the Philebus. Taking into account the divisions of the soul, the doctrine of transmigration, the contemplative nature of the philosophic life, and the character of the style, we shall not be far wrong in placing the Phaedrus
