A plant or animal fares poorly when it acts contrary to its nature; and a human being is no different. Well, then, biting, kicking, wanton imprisonment and beheading – is that what our nature entails? No; rather, acts of kindness, cooperation and good will. And so, whether you like it or not, a person fares poorly whenever he acts like an insensitive brute.
Epictetus, Discourses 4.1
