The rare coincidence, in one ugly body, of the droll and the martyr,
the keen street and market debater with the sweetest saint known to
any history at that time, had forcibly struck the mind of Plato, so
capacious of these contrasts; and the figure of Socrates, by a
necessity, placed itself in the foreground of the scene, as the fittest
dispenser of the intellectual treasurers he had to communicate. It was
a rare fortune, that this Aesod of the mob, and this robed scholar,
should meet, to make each other immortal in their mutual faculty. The
strange synthesis, in the character of Socrates, capped the synthesis
in the mind of Plato. Moreover, by this means, he was able, in the
direct way, and without envy, to avail himself of the wit and weight
of Socrates, to which unquestionably his own debt was great; and these
derived again their principal advantage from the perfect art of Plato.

It remains to say, that the defect of Plato in power is only that which
results inevitably from his quality. He is intellectual in his aim;
and, therefore, in expression, literary. Mounting into heaven, driving
into the pit, expounding the laws of the state, the passion of love,
the remorse of crime, the hope of the parting soul,--he is literary,
and never otherwise. It is almost the sole deduction from the merit
of Plato, that his writings have not,--what is, no doubt, incident
to this regnancy of intellect in his work,--the vital authority which
the screams of prophets and the sermons of unlettered Arabs and Jews
possess. There is an interval; and to cohesion, contact is necessary.

I know not what can be said in reply to this criticism, but that we
have come to a fact in the nature of things: an oak is not an orange.
The qualities of sugar remain with sugar, and those of salt, with salt.
