"All those maxims about judging others by yourself, and putting yourself in another person's place, are not, I am afraid, reliable. I had them dinned into me constantly as a child, and I was constantly trying to obey them, and constantly was astonished at the unexpected results I arrived at; and now I know that it is a proof of artlessness to suppose that other people will think and feel and hope and enjoy what you do and in the same way that you do."

And I still think at least when it comes to cruelty vs. common decency, there is something to be said in favor of "don't do to others what you don't want to have done to yourself."
