From Moral Neutrality to Effective Altruism: The Changing Scope and Significance of Moral Philosophy

Peter Singer is often described as the world’s most influential living philosopher. In 2005 Time magazine named him one of the one hundred most influential people in the world, and in 2014 he was third on the Gottlieb Duttweiler Institute’s ranking of Global Thought Leaders. He is known especially for his work on the ethics of our treatment of animals, for his controversial critique of the sanctity of life ethics in bioethics, and for his writing on the obligations of the affluent to aid those living in extreme poverty. He first became well-known internationally after the publication of Animal Liberation in 1975
