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.
