Definition
Peter Albert Singer (born 17 July 1946) is an Australian moral philosopher, bioethicist, and professor, renowned for his contributions to applied ethics, particularly in the areas of animal rights, global poverty, and bioethical issues such as euthanasia and infanticide.
Overview
Singer is the Irene Heinz Steen Professor of Bioethics at Princeton University and a laureate of the University of Melbourne. He gained international prominence with his 1975 essay “Famine, Affluence, and Morality,” in which he argued for a strong ethical duty to aid people suffering from poverty and preventable disease. His 1979 book Animal Liberation is considered a foundational text of the animal rights movement, introducing the principle of equal consideration of interests and popularizing the concept of speciesism.
Throughout his career, Singer has published extensively on utilitarianism, a normative ethical theory that assesses actions by their consequences for overall well‑being. He has been a vocal advocate for effective altruism, a philosophical and social movement encouraging individuals to use evidence and reason to maximize the positive impact of their charitable actions. Singer’s positions on controversial topics—such as permitting euthanasia for terminally ill patients, endorsing voluntary human extinction, and defending the permissibility of certain forms of infanticide—have sparked significant public debate and criticism.
In addition to scholarly work, Singer has contributed to public discourse through popular books, including The Life You Can Save (2009) and The Most Good You Can Do (2015), as well as media appearances and public lectures.
