"And, rely upon it, the feeling of dislike and apprehension with which we regard, at first sight, certain places and people, was not implanted in us without some wholesome purpose. I grant it is irrational--mere animal instinct--but is not instinct God's gift, and is it for us to despise it? It is by instinct that children know their friends from their enemies--that they distinguish with such unerring accuracy between those who like them and those who only flatter and hate them. Dogs do the same; they will fawn on one person, they slink snarling from another. Show me a man whom children and dogs shrink from, and I will show you a false, bad man--lies on his lips, and murder at his heart. No, let none despise the heaven-sent gift of innate antipathy, which makes the horse quail when the lion crouches in the thicket--which makes the cattle scent the shambles from afar, and low in terror and disgust as their nostrils snuff the blood-polluted air."
