# Peter Singer (@peter-singer)

Peter Singer is an Australian philosopher whose influential work in applied ethics asks how impartial concern for suffering should change everyday choices and public priorities. He taught bioethics at Princeton and has written extensively about animals, global poverty, charitable giving, and practical moral reasoning.

Singer's arguments are deliberately action-oriented: they connect moral status and obligation to consumption, donation, and institutional practice. His books Animal Liberation and The Life You Can Save anchor two of his best-known areas of work.
