All men who would surpass the other animals should do their best not to pass through life silently like the beasts whom nature made prone, obedient to their bellies.
SallustIf the transmigration of a soul takes place into a rational being, it simply becomes the soul of that body. But if the soul migrates into a brute beast, it follows the body outside, as a guardian spirit follows a man. For there could never be a rational soul in an irrational being.
Sallust
