We have a reason to use information which is available about such genes in our reproductive decision-making; (3) couples should selec.

Better Never to Have Been argues for a number of related, highly provocative, views: (1) Coming into existence is always a serious harm. (2) It is always wrong to have children. (3) It is wrong not to abort fetuses at the earlier stages of gestation. (4) It would be better if, as a result of there being no new people, humanity became extinct. These views may sound unbelievable--but anyone who reads Benatar will be obliged to take them seriously.

According to what we call the Principle of Procreative Beneficence, couples who decide to have a child have a significant moral reason to select the child who, given his or her genetic endowment, can be expected to enjoy the most well-being. In the first part of this paper, we introduce PB, explain its content, grounds, and implications, and defend it against various objections. In the second part, we argue that PB is superior to competing principles of procreative selection such as (...) that of procreative autonomy. In the third part of the paper, we consider the relation between PB and disability. We develop a revisionary account of disability, in which disability is a species of instrumental badness that is context- and person-relative. Although PB instructs us to aim to reduce disability in future children whenever possible, it does not privilege the normal. What matters is not whether future children meet certain biological or statistical norms, but what level of well-being they can be expected to have. (shrink)

I defend the 'Repugnant' Conclusion that for any possible population of happy people, a population containing a sufficient number of people with lives barely worth living would be better. Four lines of argument converge on this conclusion, and the conclusion has a simple, natural theoretical explanation. The opposition to the Repugnant Conclusion rests on a bare appeal to intuition. This intuition is open to charges of being influenced by multiple distorting factors. Several theories of population ethics have been devised to (...) avoid the Repugnant Conclusion, but each generates even more counterintuitive consequences. The intuition opposing the Repugnant Conclusion is thus among the best candidates for an intuition that should be revised. (shrink)

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

The idea that a world in which everyone was born “perfect” would be a world in which something valuable was missing often comes up in debates about the ethics of technologies of prenatal testing and preimplantation genetic diagnosis . This thought plays an important role in the “disability critique” of prenatal testing. However, the idea that human genetic variation is an important good with significant benefits for society at large is also embraced by a wide range of figures writing in (...) the bioethics literature, including some who are notoriously hostile to the idea that we should not select against disability. By developing a number of thought experiments wherein we are to contemplate increasing genetic diversity from a lower baseline in order to secure this value, I argue that this powerful intuition is more problematic than is generally recognized, especially where the price of diversity is the well-being of particular individuals.

Consider a duty of beneficence towards a particular individual, S, and call a reason that is grounded in that duty a “beneficence reason towards S.” Call a person who will be brought into existence by an act of procreation the “resultant person.” Is there ever a beneficence reason towards the resultant person for an agent to procreate? In this paper, I argue for such a reason by appealing to two main premises. First, we owe a pro tanto duty of beneficence (...) to future persons; and second, some of us can benefit some of those persons by procreating. In support of the first premise I reject the presentist account of time in favor of the view that future persons are just as real as presently existing persons. I then argue that future persons are like us in all the morally relevant ways, and since we owe duties of beneficence to each other, we also owe duties of beneficence to future persons. In support of the second premise I offer an account of benefiting according to which an individual can be benefited by an action even if it makes her no better off than she would have been, had the action not been performed. This account of benefiting solves what I call the “non-identity benefit problem.” Finally, I argue that having a life worth living is a benefit, and some of us can cause some persons that benefit by causing them to exist.

This article gives an account of what makes achievements valuable. Although the natural thought is that achievements are valuable because of the product, such as a cure for cancer or a work of art, I argue that the value of the product of an achievement is not sufficient to account for its overall value. Rather, I argue that achievements are valuable in virtue of their difficulty. I propose a new perfectionist theory of value that acknowledges the will as a characteristic (...) human capacity, and thus holds that the exercise of the will, and therefore difficulty, is intrinsically valuable.

abstract In this paper I develop a characterization of disability according to which disability is in no way a sub-optimal feature. I argue, however, that this conception of disability is compatible with the idea that having a disability is, at least in a restricted sense, a harm. I then go on to argue that construing disability in this way avoids many of the common objections levelled at accounts which claim that disability is not a negative feature.

Just because an angel is better than a stone, it does not follow that two angels are better than one angel and one stone. So said Aquinas (Summa contra Gentiles III, 71), and the sentiment was echoed by Leibniz. In section 118 of the Theodicy he wrote: "No substance is either absolutely precious or absolutely contemptible in the sight of God. It is certain that God attaches more importance to a man than to a lion, but I do not know (...) that we can bc sure that he prefers one man to an entire species of lions." Even Kant was bitten by this bug. In one of his pre-Critical works he was moved to say, à propos of lice, that even though they “may in our eyes be as worthless as you like, nevertheless it is of more consequence to Nature to conserve this species as a whole than to conserve a small number of members of a superior species." In these passages Aquinas, Leibniz, and Kant gave expression to a distinctive and interesting view about the value of animal species and animal populations. At its simplest, this is the view that there is a special value in the existence of animal species or in the existence of a wide variety of different animal species. But the view also goes deeper than this. An animal species, after all, is nothing over and above the individual animals which make it up, and the value which it contributes to the world must therefore be some function of the values contributed by those individual animals. At the deepest level, what the view expressed by Aquinas, Leibniz, and Kant holds is that the value which an individual animal contributes to thc world is not constant but varies with the number..

Animal rights positions face the ‘predator problem’: the suggestion that if the rights of nonhuman animals are to be protected, then we are obliged to interfere in natural ecosystems to protect prey from predators. Generally, rather than embracing this conclusion, animal ethicists have rejected it, basing this objection on a number of different arguments. This paper considers but challenges three such arguments, before defending a fourth possibility. Rejected are Peter Singer’s suggestion that interference will lead to more harm than good, (...) Sue Donaldson and Will Kymlicka’s suggestion that respect for nonhuman sovereignty necessitates non-interference in normal circumstances, and Alasdair Cochrane’s solution based on the claim that predators cannot survive without killing prey. The possibility defended builds upon Tom Regan’s suggestion that predators, as moral patients but not moral agents, cannot violate the rights of their prey, and so the rights of the prey, while they do exist, do not call for intervention. This idea is developed by a consideration of how moral agents can be more or less responsible for a given event, and defended against criticisms offered by thinkers including Alasdair Cochrane and Dale Jamieson.

abstract Most moral philosophers accept that we have obligations to provide at least some aid and assistance to distant strangers in dire need. Philosophers who extend rights and obligations to nonhuman animals, however, have been less than explicit about whether we have any positive duties to free‐roaming or ‘wild’ animals. I argue our obligations to free‐roaming nonhuman animals in dire need are essentially no different to those we have to severely cognitively impaired distant strangers. I address three objections to the (...) view that we have positive duties to free‐roaming nonhuman animals, and respond to the predation objection to animal rights. (shrink)

It is often said that while we have a strong reason not to create someone who will be badly off, we have no strong reason for creating someone who will be well off. In this paper I argue that this asymmetry is incompatible with a plausible principle of independence of irrelevant alternatives, and that a more general asymmetry between harming and benefiting is difficult to defend. I then argue that, contrary to what many have claimed, it is possible to harm (...) or benefit someone by bringing her into existence. (shrink)

When it is wrong to bring into existence someone who will be miserable, what makes it wrong is not the threat of misery hanging over the possible person, but rather the fact that if one does it there will be real misery for an actual person. This belongs in the same category as the wrongness of making a happy person miserable, or of failing to make a person less miserable than he is. These arc all matters of the (dis)utilities—the ill-fare (...) and welfare—of present and future actual people. (shrink)

Many materialists believe that we should, in principle, be able to build a conscious computing machine. Others disagree. I favour a sceptical position, but of another variety. The problem isn't that it would be impossible to create a conscious computer. The problem is that we cannot know whether it is possible. There are principled reasons for thinking that we wouldn't ever be able to confirm that allegedly conscious computers were conscious. The proper stance on computational consciousness is agnosticism. Despite this (...) agnosticism, I think we are very close to understanding the material basis of consciousness. Close, but we will never get all the way there. Our understanding of the material basis of consciousness is ineluctably incomplete. That makes me a mysterian. But I am not a defeatist mysterian. I do not think the irresolvable mysteries of consciousness prevent us from formulating concrete empirically grounded theories of consciousness. I will even outline such a theory below. I also think we can identify some properties that are necessary for consciousness, and some that are sufficient. The problem is we cannot find properties that are both. This may sound like a contradiction, but it is not. We can know necessary properties and sufficient properties without knowing necessary and sufficient properties. One can know that drinking two litres of alcohol is sufficient for intoxication, and that at least one teaspoon of alcohol is necessary without knowing the quantity that is both necessary and sufficient. In the case of consciousness, the properties we know to be sufficient are properties that computers lack. The properties we know to be necessary can be possessed by computers, but we don't know whether those properties suffice. We can equip computers with every knowable necessary property and still scratch our heads when asked whether we have managed to create artificial experience. (shrink)

From an impersonal, timeless perspective it is hard to identify good reasons why it should matter that human extinction comes later rather than sooner, particularly if we accept that it does not matter how many human beings there are. We cannot appeal to the natural narrative shape of human history for there is no such thing. We have more local and particular concerns to which we can better appeal but only if an impersonal, timeless perspective is abandoned: only from a (...) generation–centred perspective do such concerns help to make sense of our concern for the timing of our own extinction.

I argue that, according to ordinary morality, there is moral inertia, that is, moral pressure to fail to intervene in certain circumstances. Moral inertia is manifested in scenarios with a particular causal structure: deflection scenarios, where a threatening or benefiting process is diverted from a group of people to another. I explain why the deflection structure is essential for moral inertia to be manifested. I argue that there are two different manifestations of moral inertia: strict prohibitions on interventions, and constraints (...) on interventions. Finally, I discuss the connection between moral inertia and the distinction between killing and letting die (or doing and allowing harm). (shrink)

This is the fourth chapter of my dissertation, Hedonic Value (Director: Jonathan Bennett), Syracuse University, August, 1998. It is an unpublished revision of my "Is It Good to Make Happy People?" Bioethics 12 (April 1998), pp. 93-110. I systematically lay out and assess all the main arguments on each side and conclude that, Yes, it is good to add individuals to the population who would have lives worth living.
