Where we find wrongs done to animals, it is no excuse to say that more important wrongs are done to human beings, and let us concentrate on those. A wrong is a wrong, and often the little ones, when they are shrugged off as nothing, spread and do the gravest harm to ourselves and others.

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.

Regarding factory-farmed animals We owe them a merciful death, and we owe them a merciful life. And when human beings cannot do something humanely, without degrading both the creatures and ourselves, then we should not do it at all.

My point is that when you look at a rabbit and can see only a pest, or vermin, or a meal, or a commodity, or a laboratory subject, you aren't seeing the rabbit anymore. You are seeing only yourself and the schemes and appetites we bring to the world-seeing, come to think of it, like an animal instead of as a moral being with moral vision.

We live in an age when you can prowl the streets of major cities and find human beings offering themselves in store windows, or just reach for the yellow pages and have them delivered. It is the same mindset at work, spreading in our world, and after a while this attitude can find nothing very special about anything or anybody, let alone whales.

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.

When we shrink from the sight of something, when we shroud it in euphemism, that is usually a sign of inner conflict, of unsettled hearts, a sign that something has gone wrong in our moral reasoning.
