Perhaps you may remember some one saying at the beginning of our
discussion that the unjust man was profited if he had the reputation of
justice. Now that we know the nature of justice and injustice, let us
make an image of the soul, which will personify his words. First of
all, fashion a multitudinous beast, having a ring of heads of all
manner of animals, tame and wild, and able to produce and change them
at pleasure. Suppose now another form of a lion, and another of a man;
the second smaller than the first, the third than the second; join them
together and cover them with a human skin, in which they are completely
concealed. When this has been done, let us tell the supporter of
injustice that he is feeding up the beasts and starving the man. The
maintainer of justice, on the other hand, is trying to strengthen the
man; he is nourishing the gentle principle within him, and making an
alliance with the lion heart, in order that he may be able to keep down
the many-headed hydra, and bring all into unity with each other and
with themselves. Thus in every point of view, whether in relation to
pleasure, honour, or advantage, the just man is right, and the unjust
wrong.
But now, let us reason with the unjust, who is not intentionally in
error. Is not the noble that which subjects the beast to the man, or
rather to the God in man; the ignoble, that which subjects the man to
the beast? And if so, who would receive gold on condition that he was
to degrade the noblest part of himself under the worst?—who would sell
his son or daughter into the hands of brutal and evil men, for any
amount of money? And will he sell his own fairer and diviner part
without any compunction to the most godless and foul? Would he not be
worse than Eriphyle, who sold her husband’s life for a necklace? And
intemperance is the letting loose of the multiform monster, and pride
and sullenness are the growth and increase of the lion and serpent
element, while luxury and effeminacy are caused by a too great
relaxation of spirit. Flattery and meanness again arise when the
spirited element is subjected to avarice, and the lion is habituated to
become a monkey. The real disgrace of handicraft arts is, that those
who are engaged in them have to flatter, instead of mastering their
desires; therefore we say that they should be placed under the control
of the better principle in another because they have none in
themselves; not, as Thrasymachus imagined, to the injury of the
subjects, but for their good. And our intention in educating the young,
is to give them self-control; the law desires to nurse up in them a
higher principle, and when they have acquired this, they may go their
ways.
