In recent years, many non-consequentialists such as Frances Kamm and Thomas Scanlon have been puzzling over what has come to be known as the Number Problem, which is how to show that the greater number in a rescue situation should be saved without aggregating the claims of the many, a typical kind of consequentialist move that seems to violate the separateness of persons. In this article, I argue that these non-consequentialists may be making the task more difficult than necessary, because allowing aggregation does not prevent one from being a non-consequentialist. I shall explain how a non-consequentialist can still respect the separateness of persons while allowing for aggregation.

A number of international organizations have claimed that children have a right to be loved, but there is a worry that this claim may just be an empty rhetoric. In this paper, I seek to show that there could be such a right by providing a justification for this right in terms of human rights, by demonstrating that love can be an appropriate object of a duty, and by proposing that biological parents should normally be made the primary bearers of this duty, while all other able persons in appropriate circumstances have the associate duties to help biological parents discharge their duties. I also consider some policy implications of this right.

What are you and I essentially? When do you and I come into and go out of existence? A common response is that we are essentially organisms, that is, we come into existence as organisms and go out of existence when we cease to be organisms. Jeff McMahan has put forward two arguments against the Organism View: the case of dicephalus and a special case of hemispheric commissurotomy. In this paper, I defend the Organism View against these two cases. Because it is possible to devise more McMahanian-type cases, I also provide a more general solution to these kinds of cases.

Judith Jarvis Thomson's Loop Case is particularly significant in normative ethics because it questions the validity of the intuitively plausible Doctrine of Double Effect, according to which there is a significant difference between harm that is intended and harm that is merely foreseen and not intended. Recently, Frances Kamm has argued that what she calls the Doctrine of Triple Effect, which draws a distinction between acting because-of and acting in-order-to, can account for our judgment about the Loop Case. In this paper, I first argue that even if the distinction drawn by DTE can be sustained, it does not seem to apply to the Loop Case. Moreover, I question whether this distinction has any normative significance. The upshot is that I am skeptical that DTE can explain our judgment about the Loop Case.

Can there be a duty to love someone? The kind of love we will consider is the kind of highly intense interaction that two human beings seek that involves not only strongly valuing another person for the person’s sake and wanting to promote the person’s well-being for the person’s sake, but also desiring to be physically and psychologically close to each other and desiring that the other person reciprocates our love. This kind of interaction features in romantic love, parental love, love between friends, and the love of children for their parents.

In explicating his version of the Organism View, Eric Olson argues that you begin to exist only after twinning is no longer possible and that you cannot survive a process of inorganic replacement. Assuming the correctness of the Organism View, but pace Olson, I argue in this paper that the Organism View does not require that you believe either proposition. The claim I shall make about twinning helps to advance a debate that currently divides defenders of the Organism View, while the claim I shall make about inorganic replacement will help to put the Organism View on a par with its rival views by allowing it to accommodate a plausible intuition that its rivals can accommodate, namely, the intuition that you can survive a process of inorganic replacement. Both claims, I shall also argue, are important for those who are interested in the identity condition of a human organism, even if they do not hold the view that you are essentially an organism.

It is quite likely that parents will soon be able to use genetic engineering to select the sex of their child by directly manipulating the sex of an embryo. Some might think that this method would be a more ethical method of sex selection than present technologies such as preimplantation genetic diagnosis because, unlike PGD, it does not need to create and destroy “wrong gendered” embryos. This paper argues that those who object to present technologies on the grounds that the embryo is a person are unlikely to be persuaded by this proposal, though for different reasons.

The prospect of using memory modifying technologies raises interesting and important normative concerns. We first point out that those developing desirable memory modifying technologies should keep in mind certain technical and user-limitation issues. We next discuss certain normative issues that the use of these technologies can raise such as truthfulness, appropriate moral reaction, self-knowledge, agency, and moral obligations. Finally, we propose that as long as individuals using these technologies do not harm others and themselves in certain ways, and as long as there is no prima facie duty to retain particular memories, it is up to individuals to determine the permissibility of particular uses of these technologies.
