Leontius which throws some light on this question. He was coming up
from the Piraeus outside the north wall, and he passed a spot where
there were dead bodies lying by the executioner. He felt a longing
desire to see them and also an abhorrence of them; at first he turned
away and shut his eyes, then, suddenly tearing them open, he
said,—‘Take your fill, ye wretches, of the fair sight.’ Now is there
not here a third principle which is often found to come to the
assistance of reason against desire, but never of desire against
reason? This is passion or spirit, of the separate existence of which
we may further convince ourselves by putting the following case:—When a
man suffers justly, if he be of a generous nature he is not indignant
at the hardships which he undergoes: but when he suffers unjustly, his
indignation is his great support; hunger and thirst cannot tame him;
the spirit within him must do or die, until the voice of the shepherd,
that is, of reason, bidding his dog bark no more, is heard within. This
shows that passion is the ally of reason. Is passion then the same with
reason? No, for the former exists in children and brutes; and Homer
affords a proof of the distinction between them when he says, ‘He smote
his breast, and thus rebuked his soul.’
And now, at last, we have reached firm ground, and are able to infer
that the virtues of the State and of the individual are the same. For
wisdom and courage and justice in the State are severally the wisdom
and courage and justice in the individuals who form the State. Each of
the three classes will do the work of its own class in the State, and
each part in the individual soul; reason, the superior, and passion,
the inferior, will be harmonized by the influence of music and
gymnastic. The counsellor and the warrior, the head and the arm, will
act together in the town of Mansoul, and keep the desires in proper
subjection. The courage of the warrior is that quality which preserves
a right opinion about dangers in spite of pleasures and pains. The
wisdom of the counsellor is that small part of the soul which has
authority and reason. The virtue of temperance is the friendship of the
ruling and the subject principles, both in the State and in the
individual. Of justice we have already spoken; and the notion already
given of it may be confirmed by common instances. Will the just state
or the just individual steal, lie, commit adultery, or be guilty of
impiety to gods and men? ‘No.’ And is not the reason of this that the
several principles, whether in the state or in the individual, do their
own business? And justice is the quality which makes just men and just
states. Moreover, our old division of labour, which required that there
should be one man for one use, was a dream or anticipation of what was
to follow; and that dream has now been realized in justice, which
begins by binding together the three chords of the soul, and then acts
harmoniously in every relation of life.
