Peter Singer

"At one level, this movement on behalf of oppressed farm animals is emotional...Yet the movement is also the product of a deep intellectual ferment pioneered by the Princeton scholar Peter Singer...This idea popularized by Professor Singer — that we have ethical obligations that transcend our species — is one whose time appears to have come...What we’re seeing now is an interesting moral moment: a grass-roots effort by members of one species to promote the welfare of others...animal rights are now firmly on the mainstream ethical agenda."

"Inaugurated in 1975 by Peter Singer“s famous pamphlet, ”'Animal Liberation“”, philosophical research into our duties towards animals, the moral rights to be ascribed to them, how it is right to treat them, and which practices — economic, scientific, technological—are consistent with the principles of a normative ethic that includes among its “clients” the grandchildren of Bentham and Kant as much as those of Fido or Pluto, is now vast. (p. 7)"

"Living a minimally acceptable ethical life involves using a substantial part of our spare resources to make the world a better place. Living a fully ethical life involves doing the most good we can."

"To be honest, I was somewhat disappointed... It's had effects around the margins, of course, but they have mostly been minor. When I wrote it, I really thought the book would change the world. I know it sounds a little grand now, but at the time the sixties still existed for us. It looked as if real changes were possible, and I let myself believe that this would be one of them. All you have to do is walk around the corner to McDonald's to see how successful I have been."

"The evidence of our own eyes makes it more plausible to believe that the world was not created by any god at all. If, however, we insist on believing in divine creation, we are forced to admit that the god who made the world cannot be all-powerful and all good. He must be either evil or a bungler."

"Speciesism is an attitude of prejudice towards beings because they're not members of our species, so just as racism means that you're prejudiced against beings who are not members of your race and sexism means you're prejudiced against people of the other sex. So we humans tend to be speciesist in we think that any being that is a member of the species homo sapien just automatically has a higher moral status and is more important than any being that is a member of any other species, irrespective of the actual characteristics of those beings."

"Philosophy is not politics, and we do our best, within our all-too-human limitations, to seek the truth, not to score points against opponents. There is little satisfaction in gaining an easy triumph over a weak opponent while ignoring better arguments against your views."

"I never believed in a God. [...] There may have been times when I wondered if there might be a God, but it always seemed to me wildly implausible that a God worth worshipping could allow the Holocaust to occur."

"if it is in our power to prevent something bad from happening, without thereby sacrificing anything of comparable moral importance, we ought, morally, to do it."

"neither our distance from a preventable evil nor the number of other people who, in respect to that evil, are in the same situation as we are, lessens our obligation to mitigate or prevent that evil."

"People do not feel in any way ashamed or guilty about spending money on new clothes or a new car instead of giving it to famine relief. (Indeed, the alternative does not occur to them.) This way of looking at the matter cannot be justified. When we buy new clothes not to keep ourselves warm but to look "well-dressed" we are not providing for any important need. We would not be sacrificing anything significant if we were to continue to wear our old clothes, and give the money to famine relief. By doing so, we would be preventing another person from starving. It follows from what I have said earlier that we ought to give money away, rather than spend it on clothes which we do not need to keep us warm. To do so is not charitable, or generous. Nor is it the kind of act which philosophers and theologians have called "supererogatory" - an act which it would be good to do, but not wrong not to do. On the contrary, we ought to give the money away, and it is wrong not to do so."

"Animal Liberation is Human Liberation too."

"Speciesism—the word is not an attractive one, but I can think of no better term—is a prejudice or attitude of bias in favor of the interests of members of one's own species and against those of members of other species."

"Let us consider first the view that it is always wrong to take an innocent human life. We may call this the “sanctity of life” view. People who take this view oppose abortion and euthanasia. They do not usually, however, oppose the killing of nonhuman animals—so perhaps it would be more accurate to describe this view as the “sanctity of human life” view. The belief that human life, and only human life, is sacrosanct is a form of speciesism."

"[One thing] underpins, makes consistent, and gives meaning to all our other activities on behalf of animals. This one thing is that we take responsibility for our own lives, and make them as free of cruelty as we can. The first step is that we cease to eat animals. Many people who are opposed to cruelty to animals draw the line at becoming a vegetarian. It was of such people that Oliver Goldsmith, the eighteenth-century humanitarian essayist, wrote: "They pity, and they eat the objects of their compassion.""
