Benatar's asymmetry argument

Benatar's asymmetry argument for antinatalism is an argument based on the difference between harms and benefits viewed in two scenarios — when the person in question exists and when the person in question never exists. The argument, introduced by David Benatar in his book, Better Never to Have Been: The Harm of Coming into Existence, aims to establish that coming into existence is always a harm for the one who's coming into the world.
