the evil which is remediable should be dealt with more in sorrow than anger.  He who is unjust is to be pitied in any case; for no man voluntarily does evil or allows evil to exist in his soul.  And therefore he who deals with the curable sort must be long-suffering and forbearing; but the incurable shall have the vials of our wrath poured out upon him.  The greatest of all evils is self-love, which is thought to be natural and excusable, and is enforced as a duty, and yet is the cause of many errors.  The lover is blinded about the beloved, and prefers his own interests to truth and right; but the truly great man seeks justice before all things.  Self-love is the source of that ignorant conceit of knowledge which is always doing and never succeeding.  Wherefore let every man avoid self-love, and follow the guidance of those who are better than himself.  There are lesser matters which a man should recall to mind; for wisdom is like a stream, ever flowing in and out, and recollection flows in when knowledge is failing.  Let no man either laugh or grieve overmuch; but let him control his feelings in the day of good- or ill-fortune, believing that the Gods will diminish the evils and increase the blessings of the righteous.  These are thoughts which should ever occupy a good man’s mind; he should remember them both in lighter and in more serious hours, and remind others of them.

So much of divine matters and the relation of man to God.  But man is man, and dependent on pleasure and pain; and therefore to acquire a true taste respecting either is a great matter.  And what is a true taste?  This can only be explained by a comparison of one life with another.  Pleasure is an object of desire, pain of avoidance; and the absence of pain is to be preferred to pain, but not to pleasure.  There are infinite kinds and degrees of both of them, and we choose the life which has more pleasure and avoid that which has less; but we do not choose that life in which the elements of pleasure are either feeble or equally balanced with pain.  All the lives which we desire are pleasant; the choice of any others is due to inexperience.

Now there are four lives—­the temperate, the rational, the courageous, the healthful; and to these let us oppose four others—­the intemperate, the foolish, the cowardly, the diseased.  The temperate life has gentle pains and pleasures and placid desires, the intemperate life has violent delights, and still more violent desires.  And the pleasures of the temperate exceed the pains, while the pains of the intemperate exceed the pleasures.  But if this is true, none are voluntarily intemperate, but all who lack temperance are either ignorant or wanting in self-control:  for men always choose the life which (as they think) exceeds in pleasure.  The wise, the healthful, the courageous life have a similar advantage—­they also exceed their opposites in pleasure.  And, generally speaking, the life of virtue is far more pleasurable and honourable, fairer and happier far, than the life of vice.  Let this be the preamble of our laws; the strain will follow.
