“Reforms will come as all great reforms have always come in ridding us of evils against both man and animal--not as we change our moral principles but as we discern and accept the implications of principles already held.”

“I think he overlook a phase: that empathy stage in our lives when we may begin to see even the commonest animals on their own terms, fellow creatures with their own needs to meet and hardships to bear, joined with us in the mystery of life and death--and frankly, for all of our more exalted endowments, not all that much less enlightened than the sagest of naked apes about the meaning of it all.That kinship is to me reason enough to go about my own way in the world showing each one as much courtesy as I can, refraining from things that bring animals needless harm. They all seem to have enough dangers coming at them as it is. Whenever human beings with our loftier gifts and grander calling in the world can stop to think on their well-being, if only by withdrawing to let them be, it need not be a recognition of 'rights.' It is just a gracious thing, an act of clemency only more to our credit because the animals themselves cannot ask for it, or rebuke us when we transgress against them, or even repay our kindness.”

“Though reason must guide us in laying down standards and laws regarding animals, and in examining the arguments of those who reject such standards, it is usually best in any moral inquiry to start with the original motivation, which in the case of animals we may without embarrassment call love. Human beings love animals as only the higher love the lower, the knowing love the innocent, and the strong love the vulnerable. When we wince at the suffering of animals, that feeling speaks well of us even when we ignore it, and those who dismiss love for our fellow creatures as mere sentimentality overlook a good and important part of our humanity.”

“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.”

“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.”

“My earliest recollection is of coming upon some rabbit tracks in the backyard snow. I must have been three or so, but I had never seen a rabbit and can still recall the feeling of being completely captivated by the tracks: Someone had been here. And he left these prints. And he was alive. And he lived somewhere nearby, maybe even watching me at this very moment. Four decades later, I do not need to be reminded that rabbits are often a nuisance to farmers and gardeners. 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.”
