Lactantius — Divine Institutes 5.18

This is why someone who would rather go without or die than harm another or snatch something seems foolish — people think a human being is destroyed by death. From that persuasion come the errors of the crowd and of the philosophers.

If after death we are nothing, it is most foolish not to manage this life so that it lasts long and is full of every advantage — and whoever does that must leave the rule of justice. But if a better and longer life remains for a human being — which we learn from great philosophers’ arguments, oracles of seers, and divine voices of prophets — then it is the wise person’s part to despise the present with its goods, since every loss is weighed against immortality.
