Antinatalism or anti-natalism is the ethical view that negatively values procreation. Antinatalists argue that humans should abstain from procreation because it is morally wrong. In scholarly and literary writings, various ethical arguments have been presented for antinatalism. Some of the earliest surviving formulations of the idea that it would be better not to have been born can be found in ancient Greece. The term antinatalism is in opposition to the term natalism, pronatalism or pro-natalism, and was used probably for the first time as the name of the position by Théophile de Giraud in his book L'art de guillotiner les procréateurs: Manifeste anti-nataliste.
