The account of the Platonic ideas in the Meno is the simplest and clearest, and we shall best illustrate their nature by giving this first and then comparing the manner in which they are described elsewhere, e. g. in the Phaedrus, Phaedo, Republic; to which may be added the criticism of them in the Parmenides, the personal form which is attributed to them in the Timaeus, the logical character which they assume in the Sophist and Philebus, and the allusion to them in the Laws (xii. 964). In the Cratylus they dawn upon him with the freshness of a newly-discovered thought (439). The Meno (81 ff.) goes back to a former state of existence, in which men did and suffered good and evil, and received the reward or punishment of them until their sin was purged away and they were allowed to return to earth. This is a tradition of the olden time, to which priests and poets bear witness. The souls of men returning to earth bring back a latent memory of ideas, which were known to them in a former state. The recollection is awakened into life and consciousness by the sight of the things which resemble them on earth. The soul evidently possesses such innate ideas before she has had time to acquire them. This is proved by an experiment tried on one of Meno’s slaves, from whom Socrates elicits truths of arithmetic and geometry, which he had never learned in this world. He must therefore have brought them with him from another. The notion of a previous state of existence is found in the verses of Empedocles and in the fragments of Heracleitus. It was the natural answer to two questions, ‘Whence came the soul? What is the origin of evil?’ and prevailed far and wide in the East. It found its way into Hellas probably though the medium of Orphic and Pythagorean rites and mysteries. It was easier to think of a former than of a future life, because such a life has really existed for the race though not for the individual, and all men come into the world, if not ‘trailing clouds of glory,’ at any rate able to enter into the inheritance of the past. In the Phaedrus (245 ff.), as well as in the Meno, it is this former rather than a future life on which Plato is disposed to dwell. There the Gods, and men following in their train, go forth to contemplate the heavens, and are borne round in the revolutions of them. There they see the divine forms of justice, temperance, and the like, in their unchangeable beauty, but not without an effort more than human. The soul of man is likened to a charioteer and two steeds, one mortal, the other immortal. The charioteer and the mortal steed are in fierce conflict; at length the animal principle is finally overpowered, though not extinguished, by the combined energies of the passionate and rational elements. This is one of those passages in Plato which, partaking both of a philosophical and poetical character, is necessarily indistinct and inconsistent. The magnificent figure under
