Thus far we may believe that Plato was serious in his conception of the soul as a motive power, in his reminiscence of a former state of being, in his elevation of the reason over sense and passion, and perhaps in his doctrine of transmigration. Was he equally serious in the rest? For example, are we to attribute his tripartite division of the soul to the gods? Or is this merely assigned to them by way of parallelism with men? The latter is the more probable; for the horses of the gods are both white, i.e. their every impulse is in harmony with reason; their dualism, on the other hand, only carries out the figure of the chariot. Is he serious, again, in regarding love as 'a madness'? That seems to arise out of the antithesis to the former conception of love. At the same time he appears to intimate here, as in the Ion, Apology, Meno, and elsewhere, that there is a faculty in man, whether to be termed in modern language genius, or inspiration, or imagination, or idealism, or communion with God, which cannot be reduced to rule and measure. Perhaps, too, he is ironically repeating the common language of mankind about philosophy, and is turning their jest into a sort of earnest. (Compare Phaedo, Symp.) Or is he serious in holding that each soul bears the character of a god? He may have had no other account to give of the differences of human characters to which he afterwards refers. Or, again, in his absurd derivation of mantike and oionistike and imeros (compare Cratylus)? It is characteristic of the irony of Socrates to mix up sense and nonsense in such a way that no exact line can be drawn between them. And allegory helps to increase this sort of confusion.
As is often the case in the parables and prophecies of Scripture, the meaning is allowed to break through the figure, and the details are not always consistent. When the charioteers and their steeds stand upon the dome of heaven they behold the intangible invisible essences which are not objects of sight. This is because the force of language can no further go. Nor can we dwell much on the circumstance, that at the completion of ten thousand years all are to return to the place from whence they came; because he represents their return as dependent on their own good
