if not the ideas, then not the souls." In the _Phaedrus_ this conception of a former existence is embodied in one of the _Myths_ in which Plato's imaginative powers are seen at their highest. In it the soul is compared to a charioteer driving two winged steeds, one mortal, the other immortal; the one ever tending towards the earth, the other seeking ever to soar into the sky, where it may behold those blessed visions of loveliness and wisdom and goodness, which are the true nurture of the soul. When the chariots of the gods go forth in mighty and glorious procession, the soul would fain ride forth in their train; but alas! the mortal steed is ever hampering the immortal, and dragging it down. If the soul yields to this influence and descends to earth, there she takes human form, but in higher {145} or lower degree, according to the measure of her vision of the truth. She may become a philosopher, a king, a trader, an athlete, a prophet, a poet, a husbandman, a sophist, a tyrant. But whatever her lot, according to her manner of life in it, may she rise, or sink still further, even to a beast or plant. Only those souls take the form of humanity that have had _some_ vision of eternal truth. And this vision they retain in a measure, even when clogged in mortal clay. And so the soul of man is ever striving and fluttering after something beyond; and specially is she stirred to aspiration by the sight of bodily loveliness. Then above all comes the test of good and evil in the soul. The nature that has been corrupted would fain rush to brutal joys; but the purer nature looks with reverence and wonder at this beauty, for it is an adumbration of the celestial joys which he still remembers vaguely from the heavenly vision. And thus pure and holy love becomes an opening back to heaven; it is a source of happiness unalloyed on earth; it guides the lovers on upward wings back to the heaven whence they came. {146} CHAPTER XV PLATO (_continued_) _The Republic--Denizens of the cave--The Timaeus--A dream of creation_
