Each one of us was harmed by being brought into existence. That harm is not negligible, because the quality of even the best lives is very bad—and considerably worse than most people recognize it to be. Although it is obviously too late to prevent our own existence, it is not too late to prevent the existence of future possible people.

Creating new people, by having babies, is so much a part of human life that it is rarely thought even to require a justification. Indeed, most people do not even think about whether they should or should not make a baby. They just make one. In other words, procreation is usually the consequence of sex rather than the result of a decision to bring people into existence. Those who do indeed decide to have a child might do so for any number of reasons, but among these reasons cannot be the interests of the potential child. One can never have a child for that child’s sake.

Notice, by extension, that in a democracy those committed to non-procreation could never, in the long run, prevail politically against those committed to procreation.

We infrequently contemplate the harms that await any new-born child—pain, disappointment, anxiety, grief, and death. For any given child we cannot predict what form these harms will take or how severe they will be, but we can be sure that at least some of them will occur. None of this befalls the nonexistent. Only existers suffer harm.

Coming into existence is always bad for those who come into existence. In other words, although we may not be able to say of the never-existent that never existing is good for them, we can say of the existent that existence is bad for them.

As we have seen, nobody is lucky enough not to be born, everybody is unlucky enough to have been born – and particularly bad luck it is.

On my view there is no net benefit to coming into existence and thus coming into existence is never worth its costs.
