Plato then illustrates, by a highly poetical and imaginative mythe, the growth and working of love in the soul. All soul or mind is essentially self-moving, and the cause of motion to other things. It is therefore immortal, without beginning or end: the universal or cosmic soul, as well as the individual souls of Gods and men.[31] Each soul may be compared to a chariot with a winged pair of horses. In the divine soul, both the horses are excellent, with perfect wings: in the human soul, one only of them is good, the other is violent and rebellious, often disobedient to the charioteer, and with feeble or half-grown wings.[32] The Gods, by means of their wings, are enabled to ascend up to the summit of the celestial firmament--to place themselves upon the outer circumference or back of the heaven--and thus to be carried round along with the rotation of the celestial sphere round the Earth. In the course of this rotation they contemplate the pure essences and Ideas, truth and reality without either form or figure or colour: they enjoy the vision of the Absolute--Justice, Temperance, Beauty, Science. The human souls, with their defective wings, try to accompany the Gods; some attaching themselves to one God, some to another, in this ascent. But many of them fail in the object, being thrown back upon earth in consequence of their defective equipment, and the unruly character of one of the horses: some however succeed partially, obtaining glimpses of Truth and of the general Ideas, though in a manner transient and incomplete.

Plato himself calls this panegyric in the mouth of Sokrates a [Greek: muthiko/s tis u(/mnos] (Phædr. p. 265 D).] [Footnote 32: The reader will recollect Homer, Iliad, xvi. 152, where the chariot and horses of Patroklus are described, when he is about to attack the Trojans; the mortal horse Pedasus is harnessed to it alongside of the two immortal horses Xanthus and Balius.] [Side-note: Operation of such pre-natal experience upon the Intellectual faculties of man--Comparison and combination of particular sensations indispensable--Reminiscence.]
