" The biological and moral realities - to say nothing of Go's own plan, whatever it may be - do not change with our own wishes.... a person is a person just as a dog is a dog, a deer a deer, a pig a pig, and so on through the animal kingdom. And either they suffer or they do not suffer. "

― Matthew Scully , Dominion: The Power of Man, the Suffering of Animals, and the Call to Mercy
