Context

“My pupil is that savage, with this difference: Emile has thought more, he has compared ideas, seen our errors at close quarters, he is more on his guard against himself, and only judges of what he knows. It is our own passions that excite us against the passions of others; it is our self-interest which makes us hate the wicked; if they did us no harm we should pity rather than hate them. We should readily forgive their vices if we could perceive how their own heart punishes those vices.” source
