Derek Parfit famously opined that causing a person to exist with a life barely worth living can be wrong, although it is not wrong for that person. This conundrum is known as the nonidentity problem. Parfit also held that persons can, in a morally relevant sense, be caused to exist in the distant future by actions that make the agent a necessary condition for a person’s existence. When these views are combined, which he did, and applied explicitly to persons with (...) a life not worth living, which he did not, an interesting conditional conclusion can be drawn. If every family line eventually produces a person with a life not worth living, and if causing that person to exist cannot be justified by the benefits befalling others in the family line, it is always wrong to have children. Parfit did not draw this antinatalist conclusion, but an analysis of his introduction of the nonidentity problem shows that he could have. Since Parfit’s other views on population ethics continue to be discussed with relative respect, it stands to reason that the antinatalist position should be no exception. Right or wrong, it has its legitimate place in considerations concerning the future of reproduction. (shrink)

I present a qualified new defense of antinatalism. It is intended to empower potential parents who worry about their possible children’s life quality in a world threatened by environmental degradation, climate change, and the like. The main elements of the defense are an understanding of antinatalism’s historical nature and contemporary varieties, a positional theory of value based on Epicurean hedonism and Schopenhauerian pessimism, and a sensitive guide for reproductive decision-making in the light of different views on life’s value and risk-taking. (...) My conclusion, main message, to the concerned would-be parents is threefold. If they believe that life’s ordinary frustrations can make it not worth living, they should not have children. If they believe that a noticeably low life quality makes it not worth living and that such life quality can be reasonably expected, they should not have children, either. If they believe that a noticeably low life quality is not reasonably to be expected or that the risk is worth taking, they can, in the light of their own values and beliefs, have children. The conclusion is supported by a combination of the extant arguments for reproductive abstinence, namely the arguments from consent, moral asymmetry, life quality, and risk. (shrink)

Moral and political philosophers no longer condemn harm inflicted on nonhuman animals as self-evidently as they did when animal welfare and animal rights advocacy was at the forefront in the 1980s, and sentience, suffering, species-typical behavior, and personhood were the basic concepts of the discussion. The article shows this by comparing the determination with which societies seek responsibility for human harm to the relative indifference with which law and morality react to nonhuman harm. When harm is inflicted on humans, policies (...) concerning negligence and duty of care and principles such as the ‘but for’ rule and the doctrine of double effect are easily introduced. When harm is inflicted on nonhumans, this does not happen, at least not any more. As an explanation for the changed situation, the article offers a shift in discussion and its basic terminology. Simple ethical considerations supported the case for nonhuman animals, but many philosophers moved on to debate different views on political justice instead. This allowed the creation of many conflicting views that are justifiable on their own presuppositions. In the absence of a shared foundation, this fragments the discussion, focuses it on humans, and ignores or marginalizes nonhuman animals. (shrink)

Antinatalism assigns reproduction a negative value. There should be fewer or no births. Those who say that there should be fewer births have been called conditional antinatalists. A better name for their view would be selective pronatalism. Those who say that there should be no births face two challenges. They must define the scope of their no-birth policy. Does it apply only to human or sentient beings or can it also be extended to all organic life, perhaps even to machine (...) consciousness? And whatever the scope, they have to justify the eventual extinction of humankind or other life forms, an inevitable consequence of unconditional antinatalism. Different axiologies and moral theories produce different responses to these challenges. It is argued that a two-value conflict-sensitive negative utilitarianism would produce a kind and reasonable justification for ending at least human and factory-animal reproduction. The conclusion is purely moral and supports only voluntary extinction for humankind. (shrink)
