Key takeaways

  • Peter Singer belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Peter Singer to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Peter Singer from memory before moving on to harder problems.

Reference excerpt

Peter Albert David Singer (born 6 July 1946) is an Australian moral philosopher who is Emeritus Ira W. DeCamp Professor of Bioethics at Princeton University. Singer's work specialises in applied ethics, approaching the subject from a secular, utilitarian perspective. He wrote the book Animal Liberation (1975), in which he argues for vegetarianism, and the essay "Famine, Affluence, and Morality", which argues the moral imperative of donating to help the poor around the world. For most of his career he was a preference utilitarian. He revealed in The Point of View of the Universe (2014), co-authored with Katarzyna de Lazari-Radek, that he had become a hedonistic utilitarian. On two occasions, Singer served as chair of the philosophy department at Monash University, where he founded its Centre for Human Bioethics. In 1996, he stood unsuccessfully as a Greens candidate for the Australian Senate. In 2004, Singer 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 co-founder of Animals Australia and the founder of the non-profit organisation The Life You Can Save.

Early life and education

Peter Albert David Singer was born in Melbourne, Victoria, Australia, on 6 July 1946. His parents were Austrian Jews who immigrated to Australia from Vienna after Austria's annexation (Anschluss) by Nazi Germany in 1938, and settled in Melbourne. His paternal grandparents were taken by the Nazis to Łódź, and were most likely murdered, since they were never heard from again. His maternal grandfather, the educator and psychologist David Ernst Oppenheim (1881–1943), was murdered in the Theresienstadt concentration camp. Oppenheim was a member of the Vienna Psychoanalytic Society and wrote a joint article with Sigmund Freud, before joining the Adlerian Society for Individual Psychology. Singer later wrote a biography of Oppenheim. Singer is an atheist and was raised in a prosperous, non-religious family. His father had a successful business importing tea and coffee. His family rarely observed Jewish holidays, and Singer declined to have a bar mitzvah. Singer attended Preshil, and later Scotch College. After leaving school, Singer studied law, history, and philosophy as a resident of Ormond College at the University of Melbourne, earning a bachelor's degree in 1967. Singer explained that he elected to major in philosophy after his interest was piqued by discussions with his sister's then-boyfriend. He earned a master's degree for a thesis entitled Why Should I Be Moral? at the same university in 1969. He was awarded a scholarship to study at the University of Oxford and obtained from there a Bachelor of Philosophy in 1971 with a thesis on civil disobedience supervised by R. M. Hare and published as a book in 1973. Singer names Hare, Australian philosopher H. J. McCloskey and British philosopher J. L. H. Thomas, who taught him "how to read and understand Hegel", as his most important mentors. In the preface to Hegel: A Very Short Introduction, Singer recalls his time in Thomas' "remarkable" classes at Oxford where students were forced to "probe passages of the Phenomenology sentence by sentence, until they yielded their meaning". One day at Balliol College in Oxford, he had what he refers to as probably the decisive formative experience of his life. He was having a discussion after class with fellow graduate student Richard Keshen, who would later become a professor at Cape Breton University. During their lunch Keshen opted to have a salad after being told that the spaghetti sauce contained meat. Singer had the spaghetti. Singer eventually questioned Keshen about his reason for avoiding meat. Keshen explained his ethical objections. Singer would later state, "I'd never met a vegetarian who gave such a straightforward answer that I could understand and relate to." Keshen later introduced Singer to his vegetarian friends. Singer was able to find one book in which he could read up on the issue (Animal Machines by Ruth Harrison) and within a week or two he approached his wife saying that he thought they needed to make a change to their diet and that he did not think they could justify eating meat.

Academic career After spending three years as a Radcliffe lecturer at University College, Oxford, he was a visiting professor at New York University for 16 months, where he influenced the views of James Rachels and Peter Unger about animals and famine. In 1977, he returned to Melbourne where he spent most of his career, aside from appointments as visiting faculty abroad, until his move to Princeton in 1999. In June 2011 Singer joined the professoriate of New College of the Humanities, a private college in London, in addition to his work at Princeton. He gave his last lecture at Princeton in 2023, and has retired. He has been a regular contributor to Project Syndicate since 2001. According to the philosopher Helga Kuhse, Singer is almost certainly the best-known and most widely read of all contemporary philosophers. Michael Specter wrote that Singer is among the most influential of contemporary philosophers. He co-founded the open-access Journal of Controversial Ideas along with the bioethicist Francesca Minerva and the moral philosopher Jeff McMahan in 2018.

Worked examples

Example 1 — a first encounter with Peter Singer

Start with the simplest possible case. Write down what Peter Singer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Peter Singer before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Peter Singer ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Peter Singer

In research
Peter Singer appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Peter Singer in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Peter Singer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1946 births, 20th-century Australian non-fiction writers, 20th-century Australian philosophers, so understanding it makes those chapters shorter.
In everyday life
Look for Peter Singer outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
