William Brown (veterinarian)

"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."

"Have you a right to torture animals for your pleasure? Have you a right to make their lives amid terror and misery in order to derive some measure of gratification from what are called the pleasures of the chase?"

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

"Yet, like all God’s wonderful gifts to us, this great gift of pain can be turned into a horrible curse. Just in proportion as God’s love provides the possibility of good, so our vice or ignorance makes the possibility of evil. The abuse of God’s gift of pain may be the cause of the most terrible of evils, and we call it cruelty."

"When considering the extent of an animal’s capacity for suffering, it is impossible to draw a distinct line between domestic animals and so-called vermin. Such a line is purely a matter of sentiment. The fact remains that all vertebrate animals are highly sensitive."

"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."
