Our intuitions mislead us when they excuse letting distant strangers die whom a small donation would save.

Life

Peter Unger, born in 1942, is an American philosopher and professor at New York University. He first defended a radical scepticism, then argued that well-off people have a moral duty to give a great deal to save distant strangers, our usual intuitions wrongly excusing us. He has also written on metaphysics and consciousness, and later criticised the philosophy of his time.
