Seneca · On the reasons for withdrawing from the world
Letters 14.9
We should therefore look about us, and see how we may protect ourselves from the mob. And first of all, we should have no cravings like theirs; for rivalry results in strife. Again, let us possess nothing that can be snatched from us to the great profit of a plotting foe. Let there be as little booty as possible on your person. No one sets out to shed the blood of his fellow-men for the sake of bloodshed,—at any rate very few. More murderers speculate on their profits than give vent to hatred. If you are empty-handed, the highwayman passes you by; even along an infested road, the poor may travel in peace.
