Lactantius

“ If death destroys the soul, we must use our endeavours to live for a longer time, and more to our own advantage; but if there remains after death a life of immortality and blessedness, the just and wise man will certainly despise this corporeal existence, with all earthly goods, because he will know what kind of a reward he is about to receive from God. Therefore let us maintain innocency, let us maintain justice, let us undergo the appearance of foolishness, that we may be able to maintain true wisdom. ”

“ For neither reason nor nature itself permits that he who is just should not be wise, since it is plain that the just man does nothing except that which is right and good, and always avoids that which is perverted [1] and evil. But who will be able to distinguish between good and evil, depravity and rectitude, but he who shall be wise? But the fool acts badly, because he is ignorant of what is good and evil. ”

“ Therefore justice cannot be befitting to the foolish man, nor wisdom to the unjust. He is not then a foolish person who has not thrust off a shipwrecked man from a plank, nor a wounded man from his horse, because he has abstained from injury, which is a sin ”

“ But that he should appear foolish at first sight is caused by this, that they suppose the soul to be extinguished together with the body; and for this reason they refer all advantage to this life. For if there is no existence after death, it is plain that he acts foolishly who spares the life of another to his own loss, or who consults the gain of another more than his own. ”
