It is frequently claimed that breeding animals that we know will have unavoidable health problems is at least prima facie wrong, because it harms the animals concerned. However, if we take ‘harm’ to mean ‘makes worse off’, this claim appears false. Breeding an animal that will have unavoidable health problems does not make any particular individual animal worse off, since an animal bred without such problems would be a different individual animal. Yet, the intuition that there is something ethically wrong (...) about breeding animals—such as purebred pedigree dogs—in ways that seem negatively to affect welfare remains powerful. In this paper, an animal version of what is sometimes called the non-identity problem is explored, along with a number of possible ways of understanding what might be wrong with such breeding practices, if it is not that they harm the animal itself. These possibilities include harms to others, placeholder arguments, non-comparative ideas of harm, an ‘impersonal’ approach, and concerns about human attitudes and dispositions. (shrink)

In his paper The Opposite of Human Enhancement: Nanotechnology and the Blind Chicken problem (Nanoethics 2:305–316, 2008) Paul Thompson argues that the possibility of disenhancing animals in order to improve animal welfare poses a philosophical conundrum. Although many people intuitively think such disenhancement would be morally impermissible, it’s difficult to find good arguments to support such intuitions. In this brief response to Thompson, I accept that there’s a conundrum here. But I argue that if we seriously consider whether creating beings (...) can harm or benefit them, and introduce the non-identity problem to discussions of animal disehancement, the conundrum is even deeper than Thompson suggests.

According to the psychological account of personal identity, our identity is based on the continuity of psychological connections, and so we do not begin to exist until these are possible, some months after conception. This entails the psychological account faces a challenge from the non-identity problem—our intuition that someone cannot be harmed by actions that are responsible for their existence, even if these actions seem clearly to cause them harm. It is usually discussed with regard to preconception harms, but in (...) the context of the psychological account, it is also applicable to prenatal harms. Inflicting prenatal injury is widely thought to be morally impermissible, but if the injury is identity-determining on the psychological account, then no-one seems to be harmed—rather, the injury is responsible for bringing them into existence. Here, I argue that identity-determining injuries can routinely occur on the psychological account, and that this undermines the account. I assess Nicola Williams’ proposal to salvage the account based on a trans-world account of personal identity, and show that it is unsuccessful. I then show that Jeff McMahan’s embodied mind account of personal identity is also susceptible. I conclude that identity-determining prenatal injuries pose a significant challenge for the psychological account and its variants, and provide a reason for supporting alternative accounts that fix personal identity at conception.

In recent years, the question of whether prospective parents might have a moral obligation to select against disability in their offspring has piqued the attention of many prominent philosophers and bioethicists, and a large literature has emerged surrounding this question. Rather than looking to the most common arguments given in support of a positive response to the abovementioned question, such as those focusing on the harms disability may impose on the child created, duties and role-specific obligations, and impersonal ‘harms’, a (...) less commonly made set of arguments is focused upon which looks to the harms that a decision not to select against disability may impose on others. Three different possible arguments supporting a limited duty of disability avoidance are thus identified and subsequently explored: harms to parents themselves, harms to existing family members, and harms to other existing members of society.

When attempting to determine which of our acts affect future generations and which affect the identities of those who make up such generations, accounts of personal identity that privilege psychological features and person affecting accounts of morality, whilst highly useful when discussing the rights and wrongs of acts relating to extant persons, seem to come up short. On such approaches it is often held that the intuition that future persons can be harmed by decisions made prior to their existence is (...) mistaken as identity is a most fragile thing with even the smallest differences in the conditions under which we procreate affecting not the interests of distinct future persons, but the identities of those who will come to exist in the future. Within this paper I reject this view, holding that a subscription to these two accounts need not result in the conclusion that virtually all acts relating to possible persons are permitted. Further, I argue that such accounts may in fact allow a great deal more scope for the determination of prenatal harms than accounts of personal identity that privilege physical features. Finally, by interpreting claims regarding causal identity such as Parfit’s Time Dependence Claim in terms of Counterpart Theory I suggest that a solution to the non-identity problem can be found in the acceptance of, as relevant in prenatal cases, three kinds of objective similarity relations: Biological, Environmental and Decisional counterpart relations.
