final conclusion. For the definition which we believe to hold good in
states has still to be tested by the individual. Having read the large
letters we will now come back to the small. From the two together a
brilliant light may be struck out...

Socrates proceeds to discover the nature of justice by a method of
residues. Each of the first three virtues corresponds to one of the three
parts of the soul and one of the three classes in the State, although the
third, temperance, has more of the nature of a harmony than the first two.
If there be a fourth virtue, that can only be sought for in the relation of
the three parts in the soul or classes in the State to one another. It is
obvious and simple, and for that very reason has not been found out. The
modern logician will be inclined to object that ideas cannot be separated
like chemical substances, but that they run into one another and may be
only different aspects or names of the same thing, and such in this
instance appears to be the case. For the definition here given of justice
is verbally the same as one of the definitions of temperance given by
Socrates in the Charmides, which however is only provisional, and is
afterwards rejected. And so far from justice remaining over when the other
virtues are eliminated, the justice and temperance of the Republic can with
difficulty be distinguished. Temperance appears to be the virtue of a part
only, and one of three, whereas justice is a universal virtue of the whole
soul. Yet on the other hand temperance is also described as a sort of
harmony, and in this respect is akin to justice. Justice seems to differ
from temperance in degree rather than in kind; whereas temperance is the
harmony of discordant elements, justice is the perfect order by which all
natures and classes do their own business, the right man in the right
place, the division and co-operation of all the citizens. Justice, again,
is a more abstract notion than the other virtues, and therefore, from
Plato's point of view, the foundation of them, to which they are referred
