“In fact, the laboratory may be the greatest friend to dumb animals. As science advances, the lives of animals will improve as we depend less and less on their labor and no longer ignore their conditions in order to improve ours. You know, there is much to learn from animals if we are ever to be truly industrial creatures. The beaver is the finest builder of bridges and the silkworm a better weaver than any man or woman. God gave industry perfectly to the caterpillar while we must learn our arts. That is technology--our way to become closer to being like animals.”

“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.”

“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.”

“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.”

“Were the walls of our meat industry to become transparent, literally or even figuratively, we would not long continue to raise, kill, and eat animals the way we do.”

“As sentimentality towards animals can be overindulged, so, too, can grim realism, seeing only the things we want in animals and not the animals themselves.”

“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.”
