Peter Singer Quotes

The goal of maximizing the welfare of all may be better achieved by an ethic that accepts our inclinations and harnesses them so that, taken as a whole, the system works to everyone's advantage.

Animals no doubt have different interests from humans, and may experience different pleasures and pains, but the principle of equal consideration for similar interests still holds, and pleasures and pains of similar intensity and duration should be given equal weight, whether they are experienced by humans or by animals.

Beginning to reason is like stepping onto an escalator that leads upward and out of sight. Once we take the first step, the distance to be traveled is independent of our will and we cannot know in advance where we shall end.

When my ability to reason shows me that the suffering of another being is very similar to my own suffering and matters just as much to that other being as my own suffering matters to me, then my reason is showing me something that is undeniably true. ... The perspective on ourselves that we get when we take the point of view of the universe also yields as much objectivity as we need if we are to find a cause that is worthwhile in a way that is independent of our own desires. The most obvious such cause is the reduction of pain and suffering, wherever it is to be found.

Remember Bostrom’s definition of existential risk, which refers to the annihilation not of human beings, but of “Earth-originating intelligent life.” The replacement of our species by some other form of conscious intelligent life is not in itself, impartially considered, catastrophic. Even if the intelligent machines kill all existing humans, that would be...a very small part of the loss of value that Parfit and Bostrom believe would be brought about by the extinction of Earth-originating intelligent life. The risk posed by the development of AI, therefore, is not so much whether it is friendly to us, but whether it is friendly to the idea of promoting wellbeing in general, for all sentient beings it encounters, itself included.

We do not have to make self- sacrifice a necessary element of altruism. We can regard people as altruists because of the kind of interests they have rather than because they are sacrificing their interests.

Ethics is inescapable.

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.

Becoming a vegetarian is not merely a symbolic gesture. Nor is it an attempt to isolate oneself from the ugly realities of the world, to keep oneself pure and so without responsibility for the cruelty and carnage all around. Becoming a vegetarian is a highly practical and effective step one can take toward ending both the killing of nonhuman animals and the infliction of suffering upon them.

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.

We are responsible not only for what we do but also for what we could have prevented.

I am a utilitarian. I am also a vegetarian. I am a vegetarian because I am a utilitarian.

It is easy for us to criticize the prejudices of our grandfathers, from which our fathers freed themselves. It is more difficult to search for prejudices among the beliefs and values that we hold.

It is now generally accepted that the roots of our ethics lie in patterns of behavior that evolved among our pre-human ancestors, the social mammals and that we retain within our biological nature elements of these evolved responses. We have learned considerably more about these responses, and we are beginning to to understand how they interact with our capacity to reason.

Since ancient times, philosophers have maintained that to strive too hard for one's own happiness is self-defeating.
