“One particularly poor argument in defence of eating meat is that if humans did not eat animals, those animals would not have been brought into existence in the first place. Humans would simply not have bred them in the numbers they do breed them. The claim is that although these animals are killed, this cost to them is outweighed by the benefit to them of having been brought into existence. This is an appalling argument for many reasons. First, the lives of many of these animals are so bad that even if one rejected my argument one would still have to think that they were harmed by being brought into existence. Secondly, those who advance this argument fail to see that it could apply as readily to human babies that are produced only to be eaten. Here we see quite clearly that being brought into existence only to be killed for food is no benefit. It is only because killing animals is thought to be acceptable that the argument is thought to have any force.”

“Bringing people into existence as well as failing to bring people into existence can be regretted. However, only bringing people into existence can be regretted for the sake of the person whose existence was contingent on our decision. This is not because those who are not brought into existence are indeterminate. Instead it is because they never exist. We can regret, for the sake of an indeterminate but existent person that a benefit was not bestowed on him or her, but we cannot regret, for the sake of somebody who never exists and thus cannot thereby be deprived, a good that this never existent person never experiences. One might grieve about not having had children, but not because the children that one could have had have been deprived of existence. Remorse about not having children is remorse for ourselves—sorrow about having missed childbearing and child-rearing experiences. However, we do regret having brought into existence a child with an unhappy life, and we regret it for the child’s sake, even if also for our own sakes. The reason why we do not lament our failure to bring somebody into existence is because absent pleasures are not bad.”

“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.”

“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.”

“It is unlikely that many people will take to heart the conclusion that coming into existence is always a harm. It is even less likely that many people will stop having children. By contrast, it is quite likely that my views either will be ignored or will be dismissed. As this response will account for a great deal of suffering between now and the demise of humanity, it cannot plausibly be thought of as philanthropic. That is not to say that it is motivated by any malice towards humans, but it does result from a self-deceptive indifference to the harm of coming into existence.”

“Isn`t man an amazing animal? He kills wildlife - birds, kangaroos, deer, all kinds of cats, coyotes, beavers, groundhogs, mice, foxes, and dingoes - by the millions in order to protect his domestic animals and their feed. Then he kills domestic animals by the billions and eats them. This in turn kills man by the million, because eating all those animals leads to degenerative - and fatal - health conditions like heart disease, kidney disease, and cancer. So then man tortures and kills millions more animals to look for cures for these diseases. Elsewhere, millions of other human beings are being killed by hunger and malnutrition because food they could eat is being used to fatten domestic animals. Meanwhile, some people are dying of sad laughter at the absurdity of man, who kills so easily and so violently, and once a year sends out a card praying for 'Peace on Earth.”
