From More Intelligent Life:
The Big Question: we asked six writers, how many children should we have? David Benatar believes that the only way to prevent harm is not to have any
Millions of years of evolutionary history have programmed you to reject the notion that procreation is wrong. Bear this in mind if you rush to reject my argument, and to defend a deeply harmful practice. Morally responsible parents wish to spare their children pain. There are ways they can minimise the chances of their children suffering certain types of harm, but the only way to prevent harm altogether is to desist from bringing children into existence. Any child will, inevitably, suffer considerable harm. Privileged procreators in developed countries are inclined to respond that their children are likely to be spared the chronic deprivation, insecurity and violence that blight the lives of so many. This response ignores the discomfort, distress, frustration and unhappiness that characterise even the most charmed lives. It also ignores the appalling fates that can befall anybody. These include assault, devastating injury, degenerative disease and depression.
Nor can these fates be dismissed as improbable. For example, 40% of men and 37% of women in Britain develop cancer at some point. Add to these odds the cumulative risks of other terrible conditions and we find that the chance of escaping calamity approaches zero. It reaches zero if we include death. In creating a child you are ultimately responsible for its death, and for the ensuing ripples of bereavement.
