Letters 73.13

In what respect is Jupiter superior to our good man? His goodness lasts longer; but the wise man does not set a lower value upon himself, just because his virtues are limited by a briefer span. Or take two wise men; he who has died at a greater age is not happier than he whose virtue has been limited to fewer years: similarly, a god has no advantage over a wise man in point of happiness, even though he has such an advantage in point of years. That virtue is not greater which lasts longer.
