It would be nonsense to say that it was not in the interests of a stone to be kicked along the road...A stone has no interests because it cannot suffer. The capacity for suffering and enjoyment is, however, not only necessary, but also sufficient for us to say that a being has interests - at an absolute minimum, an interest in not suffering. A mouse, for example, does have an interest in not being kicked along the road because it will suffer if it is.

We should give the same respect to the lives of animals as we do to the lives of humans.

So, basically, my view is I don't want to support the exploitation of animals, and within reason, I will do what I can to avoid it, but it's not like it's a religion for me. It's not like I consider I'm polluted if somehow some bit of milk or cheese or something passes my lips.

If you earn a lot of money, you can give away a lot of money.

I don't think nationalism is alone holding the field; it's in contention with a lot of different things.

As for cages themselves, an ordinary citizen who kept dogs in similar conditions for their entire lives would risk prosecution for cruelty. A pig producer who keeps an animal of comparable intelligence in this manner, however, is more likely to be rewarded with a tax concession or, in some countries, a direct government subsidy.

When you look at food as an ethical issue in the Christian tradition, you don't find very much about it. You don't find, as you do in the Jewish or Islamic or Hindu traditions, a lot of restrictions saying you can eat this but you can't eat that. But what you do find is the idea that gluttony is a sin and that it's something that we ought to be ashamed of.
