You may see what endurance might effect in us if you observe what labour does among tribes that are naked and rendered stronger by want. Look at all the nations that dwell beyond the Roman Empire: I mean the Germans and all the nomad tribes that war against us along the Danube. They suffer from eternal winter, and a dismal climate, the barren soil grudges them sustenance, they keep off the rain with leaves or thatch, they bound across frozen marshes, and hunt wild beasts for food. Do you think them unhappy? There is no unhappiness in what use has made part of one’s nature: by degrees men find pleasure in doing what they were first driven to do by necessity. They have no homes and no resting-places save those which weariness appoints them for the day; their food, though coarse, yet must be sought with their own hands; the harshness of the climate is terrible, and their bodies are unclothed. This, which you think a hardship, is the mode of life of all these races: how then can you wonder at good men being shaken, in order that they may be strengthened?
