To us it seems incredible that the Greek philosophers should have scanned so deeply into right and wrong and yet never noticed the immorality of slavery. Perhaps 3000 years from now it will seem equally incredible that we do not notice the immorality of our own oppression of animals.

The person who kills for fun is announcing that, could he get away with it, he'd kill you for fun. Your...life may be of no consequence to anyone else but is invaluable to you because it's the only one you've got. Exactly the same is true of each individual deer, hare, rabbit, fox, fish, pheasant and butterfly. Humans should enjoy their own lives, not taking others'.

I don't hold animals superior or even equal to humans. The whole case for behaving decently to animals rests on the fact that we are the superior species. We are the species uniquely capable of imagination, rationality, and moral choice - and that is precisely why we are under an obligation to recognize and respect the rights of animals.

"Sentimentalist" is the abuse with which people counter the accusation that they are cruel, thereby implying that to be sentimental is worse that to be cruel, which it isn't.

To my mind, the two most fascinating subjects in the universe are sex and the eighteenth century.

I don't myself believe that, even when we fulfil our minimum obligation not to cause pain, we have the right to kill animals.
