"I’m a Sentientist because all suffering matters morally and because evidence and reason are the only ways to really understand our world."
Peter is often referred to as the “world’s most influential living philosopher.” He is the Ira W. DeCamp Professor of Bioethics at Princeton University. He specialises in applied ethics, approaching the subject from a secular, naturalistic, utilitarian perspective. He wrote the books "Animal Liberation", Why Vegan? and "Animal Liberation Now!" (launched on the same day as our Sentientism episode!), in which he argues against speciesism and for a shift to plant-based food systems and veganism. He also wrote the essay "Famine, Affluence, and Morality" and the books "The Life You Can Save" & "The Most Good You Can Do" which argue for effective altruism - using evidence & reasoning to do the most good we can for all sentient beings both human and not.
In 2004 Peter was recognised as the Australian Humanist of the Year by the Council of Australian Humanist Societies. In 2005, the Sydney Morning Herald placed him among Australia's ten most influential public intellectuals. Singer is a cofounder of Animals Australia & the founder of The Life You Can Save. In 2021 he received the Berggruen Prize for Philosophy and Culture. Peter donated the $1 million prize money to the most effective organizations working to assist people in extreme poverty and to reduce the suffering of animals in factory farms.
Peter has a sentiocentric moral scope. He is an atheist and has a naturalistic worldview.
