A defect in Plato's criminal jurisprudence is his remission of the
punishment when the homicide has obtained the forgiveness of the
murdered person; as if crime were a personal affair between
individuals, and not an offence against the State. There is a ridiculous
disproportion in his punishments. Because a slave may fairly receive
a blow for stealing one fig or one bunch of grapes, or a tradesman for
selling adulterated goods to the value of one drachma, it is rather
hard upon the slave that he should receive as many blows as he has taken
grapes or figs, or upon the tradesman who has sold adulterated goods
to the value of a thousand drachmas that he should receive a thousand
blows.
II. But before punishment can be inflicted at all, the legislator
must determine the nature of the voluntary and involuntary. The great
question of the freedom of the will, which in modern times has been worn
threadbare with purely abstract discussion, was approached both by Plato
and Aristotle--first, from the judicial; secondly, from the sophistical
point of view. They were puzzled by the degrees and kinds of crime; they
observed also that the law only punished hurts which are inflicted by a
voluntary agent on an involuntary patient.
In attempting to distinguish between hurt and injury, Plato says that
mere hurt is not injury; but that a benefit when done in a wrong spirit
may sometimes injure, e.g. when conferred without regard to right and
wrong, or to the good or evil consequences which may follow. He means
to say that the good or evil disposition of the agent is the principle
which characterizes actions; and this is not sufficiently described by
the terms voluntary and involuntary. You may hurt another involuntarily,
and no one would suppose that you had injured him; and you may hurt him
voluntarily, as in inflicting punishment--neither is this injury; but if
you hurt him from motives of avarice, ambition, or cowardly fear, this
is injury. Injustice is also described as the victory of desire or
passion or self-conceit over reason, as justice is the subordination of
them to reason. In some paradoxical sense Plato is disposed to affirm
all injustice to be involuntary; because no man would do injustice who
knew that it never paid and could calculate the consequences of what
he was doing. Yet, on the other hand, he admits that the distinction of
voluntary and involuntary, taken in another and more obvious sense, is
the basis of legislation. His conception of justice and injustice is
complicated (1) by the want of a distinction between justice and virtue,
that is to say, between the quality which primarily regards others, and
the quality in which self and others are equally regarded; (2) by the
confusion of doing and suffering justice; (3) by the unwillingness to
renounce the old Socratic paradox, that evil is involuntary.
