A good man prefers to suffer rather than overcome injustice with evil.
It is not only spirits who punish the evil, the soul brings itself to judgment: and also it is not right for those who endure for ever to attain everything in a short time: and also, there is need of human virtue. If punishment followed instantly upon sin, men would act justly from fear and have no virtue.
The Gods being good and making all things, there is no positive evil, it only comes by absence of good; just as darkness itself does not exist, but only comes about by absence of light.
Souls are punished when they have gone forth from the body, some wandering among us, some going to hot or cold places of the earth, some harassed by spirits. Under all circumstances they suffer with the irrational part of their nature, with which they also sinned. For its sake there subsists that shadowy body which is seen about graves, especially the graves of evil livers.
When the prizes fall to the lot of the wicked, you will not find many who are virtuous for virtue's sake.
