“We recognize the chicken as another conscious being. It's different from us, but it has a life, and if something is really important for that chicken, if it would work hard to try to get it, and if we can give it without sacrificing something that's really important to us, then we should.”

Australian moral philosopher

Peter Singer is an Australian moral philosopher, best known for his work in applied ethics and for shaping modern debates about animal welfare and global poverty. He is Emeritus Ira W. DeCamp Professor of Bioethics at Princeton University. His book Animal Liberation, published in 1975, criticized intensive animal farming and speciesism and helped shape the animal rights movement. He is also known for "Famine, Affluence, and Morality," which argues that people have a moral duty to help the global poor, and for later books including The Life You Can Save and The Most Good You Can Do, which influenced the effective altruism movement. He has worked from a secular, utilitarian perspective throughout much of his career.
