When we really understand what pain has to teach us, we shall in large measure have abolished suffering. - William Brown

Every form of cruelty—whether it be trapping, hunting, the working of ponies in mines, or the practice of vivisection—casts a slur on humanity. These actions demand our attention if we are to make progress as a truly humane society.

I have observed cats and dogs, horses, cattle and sheep under every kind of pain, and I do unhesitatingly say that they suffer as we suffer.

Much has also been said about the cruelties inflicted by animals upon one another. But I must emphasize that, in their original wild state, and with rare exceptions, animals kill only for food, not for the sake of killing. That is a prerogative peculiar to humankind.
