It has been objected that justice is honesty in the sense of Glaucon
and Adeimantus, but is taken by Socrates to mean all virtue. May we not
more truly say that the old-fashioned notion of justice is enlarged by
Socrates, and becomes equivalent to universal order or well-being,
first in the State, and secondly in the individual? He has found a new
answer to his old question (Protag.), ‘whether the virtues are one or
many,’ viz. that one is the ordering principle of the three others. In
seeking to establish the purely internal nature of justice, he is met
by the fact that man is a social being, and he tries to harmonise the
two opposite theses as well as he can. There is no more inconsistency
in this than was inevitable in his age and country; there is no use in
turning upon him the cross lights of modern philosophy, which, from
some other point of view, would appear equally inconsistent. Plato does
not give the final solution of philosophical questions for us; nor can
he be judged of by our standard.
The remainder of the Republic is developed out of the question of the
sons of Ariston. Three points are deserving of remark in what
immediately follows:—First, that the answer of Socrates is altogether
indirect. He does not say that happiness consists in the contemplation
of the idea of justice, and still less will he be tempted to affirm the
Stoical paradox that the just man can be happy on the rack. But first
he dwells on the difficulty of the problem and insists on restoring man
to his natural condition, before he will answer the question at all. He
too will frame an ideal, but his ideal comprehends not only abstract
justice, but the whole relations of man. Under the fanciful
illustration of the large letters he implies that he will only look for
justice in society, and that from the State he will proceed to the
individual. His answer in substance amounts to this,—that under
favourable conditions, i.e. in the perfect State, justice and happiness
will coincide, and that when justice has been once found, happiness may
be left to take care of itself. That he falls into some degree of
inconsistency, when in the tenth book he claims to have got rid of the
rewards and honours of justice, may be admitted; for he has left those
which exist in the perfect State. And the philosopher ‘who retires
under the shelter of a wall’ can hardly have been esteemed happy by
him, at least not in this world. Still he maintains the true attitude
of moral action. Let a man do his duty first, without asking whether he
will be happy or not, and happiness will be the inseparable accident
which attends him. ‘Seek ye first the kingdom of God and his
righteousness, and all these things shall be added unto you.’
