Few prospective procreators consider the aesthetic impact of their potential children. But how many more producers of excrement and urine, flatulence… - David Benatar

Consider an analogy. If one is playing a game of backgammon, it is entirely reasonable to make various moves. Indeed, one is not playing backgammon unless one is making (permitted) moves. There are justifications for this move and for that one. It is an entirely different matter to ask what the point of backgammon is, whether one should be playing backgammon at all, and whether one should pass it on to the next generation (by teaching it to children—or by creating children to whom one can teach it). Similarly, it can be entirely reasonable to relieve headaches and prevent harms to children and yet worry that one’s life as a whole—or human life in general—has no cosmic purpose. The absence of cosmic meaning may provide one with a reason to regret one’s existence or to desist from perpetuating the whole pointless trajectory by abstaining from bringing new people into existence.

Humans inflict untold suffering and death on many billions of animals every year, and the overwhelming majority of humans are heavily complicit.

A charmed life is so rare that for every one such life there are millions of wretched lives. Some know that their baby will be among the unfortunate. Nobody knows, however, that their baby will be one of the allegedly lucky few. Great suffering could await any person that is brought into existence. Even the most privileged people could give birth to a child that will suffer unbearably, be raped, assaulted, or be murdered brutally. The optimist surely bears the burden of justifying this procreational Russian roulette. Given that there are no real advantages over never existing for those who are brought into existence, it is hard to see how the significant risk of serious harm could be justified. If we count not only the unusually severe harms that anybody could endure, but also the quite routine ones of ordinary human life, then we find that matters are still worse for cheery procreators. It shows that they play Russian roulette with a fully loaded gun—aimed, of course, not at their own heads, but at those of their future offspring.
