Context

“creatures like us who actually find hatred such a pleasure that to give it up is like giving up beer or tobacco... 8 THE GREAT SIN I now come to that part of Christian morals where they differ most sharply from all other morals. There is one vice of which no man in the world is free; which every one in the world loathes when he sees it in someone else; and of which hardly any people, except Christians, ever imagine that they are guilty themselves. I have heard people admit that they are bad-tempered, or that they cannot keep their heads about girls or drink, or even that they are cowards.” source
