Peter Singer

Peter Singer is an Australian moral philosopher and the Ira W. DeCamp Professor of Bioethics at Princeton University. He is a leading figure in applied ethics and utilitarianism, whose provocative writings on animal rights, global poverty, and bioethics have sparked international debate and inspired social movements. His seminal 1975 book, Animal Liberation, is widely credited with launching the modern animal rights movement, while his advocacy for effective altruism has influenced philanthropic giving worldwide.

Biography

Born in Melbourne to Austrian-Jewish parents who emigrated from Vienna following the Anschluss, Singer attended Presbyterian Ladies' College and later studied law, history, and philosophy at the University of Melbourne. He pursued graduate studies at Oxford under the supervision of R. M. Hare, where he was influenced by utilitarian thought. His early academic career included positions at University College, Oxford, New York University, and La Trobe University, before he joined Monash University, where he founded its Centre for Human Bioethics. In 1999, he began his tenure at Princeton University, holding a joint appointment at the University of Melbourne. His life and work have been the subject of numerous documentaries and profiles, including in The New Yorker.

Philosophical work

Singer's philosophical approach is grounded in preference utilitarianism, arguing that the right action is the one that maximizes the satisfaction of preferences or interests. He famously applies this principle beyond the human species in his 1975 essay "Famine, Affluence, and Morality", which argues for a radical obligation to assist those in extreme poverty. His book Practical Ethics systematically applies utilitarian reasoning to contentious issues including abortion, euthanasia, infanticide, and environmental ethics. His work in bioethics has engaged with debates on embryonic stem cell research and the moral status of great apes, contributing to projects like the Great Ape Project.

Animal liberation

In his groundbreaking book Animal Liberation, Singer argues that the capacity for suffering, or sentience, grants a being moral consideration, a principle he terms the equal consideration of interests. He rigorously critiques practices in factory farming and animal testing, labeling such institutionalized exploitation as speciesism, a prejudice analogous to racism or sexism. This work provided the philosophical foundation for organizations like People for the Ethical Treatment of Animals and influenced legislative changes concerning animal welfare in several countries. His arguments extend to the ethics of vegetarianism and veganism as moral imperatives.

Effective altruism

Singer is a central intellectual force behind the effective altruism movement, which uses evidence and reason to determine the most effective ways to benefit others. His 2009 book The Life You Can Save argues that individuals in affluent nations have a profound moral duty to donate a significant portion of their income to highly effective charities, such as those fighting malaria through the Against Malaria Foundation. He co-founded The Life You Can Save organization to promote this idea and has influenced philanthropic entrepreneurs like Cari Tuna and Dustin Moskovitz. His ideas are further explored in the movement's associated literature and research from the Centre for Effective Altruism.

Public engagement and criticism

Singer's controversial positions, particularly on infanticide for severely disabled newborns and the moral value of non-human animals, have frequently sparked protest and debate. His lectures have been disrupted by disability rights activists and religious groups, notably at Zurich and Canterbury. Critics from various perspectives, including Francis Fukuyama and disability advocates like Harriet McBryde Johnson, have challenged his views. Despite this, his influence remains vast; he has written for The Guardian, Project Syndicate, and appeared on programs like The Colbert Report, and he was awarded the Berggruen Prize for Philosophy & Culture in 2021.
