Antinatalism, or anti-natalism, is a philosophical stance and social movement that gives a negative value to starting life. Antinatalists argue that humans (and sometimes other sentient beings) should stop making kids because it is morally bad. People who believe that making kids is morally good are called natalists. The term antinatalism was likely used for the first time by Belgian author Théophile de Giraud in his book "L'art de guillotiner les procréateurs: Manifeste anti-nataliste". South African philosopher David Benatar has also published books in support of antinatalism.
