Sometimes tradition and habit are just that, comfortable excuses to leave things be, even when they are unjust and unworthy. Sometimes--not often, but sometimes--the cranks and radicals turn out to be right. Sometimes Everyone is wrong.

Factory farming isn't just killing: It is negation, a complete denial of the animal as a living being with his or her own needs and nature. It is not the worst evil we can do, but it is the worst evil we can do to them.

The only thing worse than cruelty is delegated cruelty.

If we are defined by reason and morality, then reason and morality must define our choices, even when animals are concerned. When people say, for example, that they like their veal or hot dogs too much to ever give them up, and yeah it's sad about the farms but that's just the way it is, reason hears in that the voice of gluttony. We can say that what makes a human being human is precisely the ability to understand that the suffering of an animal is more important than the taste of a treat.

Animals are more than ever a test of our character, of mankind's capacity for empathy and for decent, honorable conduct and faithful stewardship. We are called to treat them with kindness, not because they have rights or power or some claim to equality, but in a sense because they don't; because they all stand unequal and powerless before us.

Go into the largest livestock operation, search out the darkest and tiniest stall or pen, single out the filthiest, most forlorn little lamb or pig or calf, and that is one of God's creatures you're looking at, morally indistinguishable from your beloved Fluffy or Frisky.

Animals have this way of constantly confronting us with ultimate questions - about truth and falsehood, guilt and innocence, God and sanctity and the soul - forcing us to define ourselves and our relationship to the world.
