Plato, The Republic

  5

  Good temper is a mean with respect to anger; the middle state
being unnamed, and the extremes almost without a name as well, we
place good temper in the middle position, though it inclines towards
the deficiency, which is without a name. The excess might called a
sort of 'irascibility'. For the passion is anger, while its causes are
many and diverse.

  The man who is angry at the right things and with the right
people, and, further, as he ought, when he ought, and as long as he
ought, is praised. This will be the good-tempered man, then, since
good temper is praised. For the good-tempered man tends to be
unperturbed and not to be led by passion, but to be angry in the
manner, at the things, and for the length of time, that the rule
dictates; but he is thought to err rather in the direction of
deficiency; for the good-tempered man is not revengeful, but rather
tends to make allowances.

  The deficiency, whether it is a sort of 'inirascibility' or whatever
it is, is blamed. For those who are not angry at the things they
should be angry at are thought to be fools, and so are those who are
not angry in the right way, at the right time, or with the right
persons; for such a man is thought not to feel things nor to be pained
by them, and, since he does not get angry, he is thought unlikely to
defend himself; and to endure being insulted and put up with insult to
one's friends is slavish.

  The excess can be manifested in all the points that have been
named (for one can be angry with the wrong persons, at the wrong
things, more than is right, too quickly, or too long); yet all are not
found in the same person. Indeed they could not; for evil destroys
even itself, and if it is complete becomes unbearable. Now
hot-tempered people get angry quickly and with the wrong persons and
at the wrong things and more than is right, but their anger ceases
quickly-which is the best point about them. This happens to them
because they do not restrain their anger but retaliate openly owing to
their quickness of temper, and then their anger ceases. By reason of
excess choleric people are quick-tempered and ready to be angry with
everything and on every occasion; whence their name. Sulky people
are hard to appease, and retain their anger long; for they repress
their passion. But it ceases when they retaliate; for revenge relieves
them of their anger, producing in them pleasure instead of pain. If
this does not happen they retain their burden; for owing to its not
being obvious no one even reasons with them, and to digest one's anger
in oneself takes time. Such people are most troublesome to
themselves and to their dearest friends. We call had-tempered those
who are angry at the wrong things, more than is right, and longer, and
cannot be appeased until they inflict vengeance or punishment.

  To good temper we oppose the excess rather than the defect; for
not only is it commoner since revenge is the more human), but
bad-tempered people are worse to live with.

  What we have said in our earlier treatment of the subject is plain
also from what we are now saying; viz. that it is not easy to define
how, with whom, at what, and how long one should be angry, and at what
point right action ceases and wrong begins. For the man who strays a
little from the path, either towards the more or towards the less,
is not blamed; since sometimes we praise those who exhibit the
deficiency, and call them good-tempered, and sometimes we call angry
people manly, as being capable of ruling. How far, therefore, and
how a man must stray before he becomes blameworthy, it is not easy
to state in words; for the decision depends on the particular facts
and on perception. But so much at least is plain, that the middle
state is praiseworthy- that in virtue of which we are angry with the
right people, at the right things, in the right way, and so on,
while the excesses and defects are blameworthy- slightly so if they
are present in a low degree, more if in a higher degree, and very
much if in a high degree. Evidently, then, we must cling to the
middle state.- Enough of the states relative to anger.
