Australian utilitarian philosopher who argues that the well-off should give far more to fight poverty and stop causing animals needless suffering.
See it on the Philosophy map →The idea
Idea: if you can prevent something very bad without sacrificing anything of comparable importance, you ought to. His drowning child: you would ruin your shoes to save a child drowning in a pond, so distance cannot excuse ignoring children dying of poverty ('Famine, Affluence, and Morality', 1972). Animal Liberation (1975) attacked 'speciesism', discounting animals' suffering just because they are not human. Main objection: his views demand nearly unlimited sacrifice, and his writing on severe disability and infanticide drew fierce protest.
Why it matters
He made global poverty and animal welfare core topics in ethics, helped launch the modern animal rights movement, and inspired effective altruism.
Legacy and sources
His books and essays, including Practical Ethics (1979) and The Life You Can Save (2009). He studied at Melbourne and Oxford and taught at Princeton from 1999.
Still debated
Whether morality can really demand so much, and whether strictly impartial concern is even humanly possible, is debated; Bernard Williams argued such demands threaten personal integrity.
Connections (3)
▸Utilitarianism: the greatest happiness principle is applied by Peter Singer: the drowning child and Animal LiberationWell documented
The connection
Utilitarianism says the right act produces the most well-being, counting everyone equally. Singer applied this strictly: a child's life abroad counts as much as one nearby, and animals' suffering counts too. As Bentham wrote, 'The question is not, Can they reason? nor, Can they talk? but, Can they suffer?'
When and how
Singer studied at Oxford under R. M. Hare, a preference utilitarian; 'Famine, Affluence, and Morality' (1972) and Animal Liberation (1975) followed.
How we know
Singer calls himself a utilitarian, quotes Bentham in Animal Liberation, and lays out the framework in Practical Ethics (1979). He later moved from preference to pleasure-based utilitarianism (2014).
Debates and open questions
The drowning-child argument needs only a weaker principle, not full utilitarianism, so how much his conclusions depend on the theory is debated.
▸Peter Singer: the drowning child and Animal Liberation helped found Applied ethics (bioethics, animals, global poverty)Well documented
The connection
Singer showed that rigorous moral argument could tackle urgent public issues and reach unsettling conclusions. His famine essay and Animal Liberation became staples of applied ethics courses, his Practical Ethics became a standard introduction, and he helped build bioethics institutions.
When and how
Melbourne and Oxford in the 1970s; with Helga Kuhse he co-founded Monash University's Centre for Human Bioethics (1980) and the journal Bioethics (1987).
How we know
His essays are among the most reprinted in applied ethics anthologies, and Practical Ethics (1979) has gone through three editions.
Debates and open questions
Many others, including Thomson, Foot and the Hastings Center founders, built the field; how much credit Singer deserves versus the wider 1970s movement varies by account.
▸Peter Singer: the drowning child and Animal Liberation inspired Effective altruism and longtermismWell documented
The connection
Singer's drowning-child argument says the well-off must give much more, and give where it helps most. Early effective altruists, such as Toby Ord, took this as a call to action. Singer then joined them, writing books on how to choose the most effective charities.
When and how
Ord and Will MacAskill founded Giving What We Can at Oxford in 2009; Singer wrote The Life You Can Save (2009) and The Most Good You Can Do (2015).
How we know
The founders cite Singer's 1972 essay as formative, and Singer became a leading public advocate, including a 2013 TED talk on effective altruism.
Debates and open questions
Singer's focus on proven poverty charities differs from the later longtermist turn; how closely the movement still follows his original argument is debated.
