Peter Singer is sometimes called "the world’s most influential living philosopher" although he thinks that if that is true, it doesn't say much for all the other living philosophers around today. He has also been called the father (or grandfather?) of the modern animal rights movement, even though he doesn't base his philosophical views on rights, either for humans or for animals.
In 2005 Time magazine named Singer one of the 100 most influential people in the world, and the Gottlieb Duttweiler Institute ranked him 3rd among Global Thought Leaders for 2013. (He crashed to 68th the following year, after GDI changed its methodology, which just shows how fleeting fame can be.) He is known especially for his work on the ethics of our treatment of animals, for his controversial critique of the sanctity of life doctrine in bioethics, and for his writings on the obligations of the affluent to aid those living in extreme poverty.
Singer first became well-known internationally after the publication of Animal Liberation in 1975. In 2011 Time included Animal Liberation on its “All-TIME” list of the 100 best nonfiction books published in English since the magazine began, in 1923. Singer has written, co-authored, edited or co-edited more than 40 books, including Practical Ethics; The Expanding Circle; How Are We to Live?, Rethinking Life and Death, The Ethics of What We Eat (with Jim Mason), The Life You Can Save, The Point of View of the Universe (with Katarzyna de Lazari-Radek), and, most recently, The Most Good You Can Do. His works have appeared in more than 25 languages.
Peter Singer was born in Melbourne, Australia, in 1946, and educated at the University of Melbourne and the University of Oxford. After teaching in England, the United States and Australia, he has, since 1999, been Ira W. DeCamp Professor of Bioethics in the University Center for Human Values at Princeton University. Since 2005 he has combined that position with the position of Laureate Professor at the University of Melbourne, in the School of Historical and Philosophical Studies. He is married, with three daughters and four grandchildren. His recreations include hiking and surfing. In 2012 he was made a Companion of the Order of Australia, the nation’s highest civic honour.
