An important objection to preference-satisfaction theories of well-being is that these theories cannot make sense of interpersonal comparisons of well-being. A tradition dating back to Harsanyi () attempts to respond to this objection by appeal to so-called extended preferences: very roughly, preferences over situations whose description includes agents’ preferences. This paper examines the prospects for defending the preference-satisfaction theory via this extended preferences program. We argue that making conceptual sense of extended preferences is less problematic than others have supposed, but (...) that even so extended preferences do not provide a promising way for the preference satisfaction theorist to make interpersonal well-being comparisons. Our main objection takes the form of a trilemma: depending on how the theory based on extended preferences is developed, either the result will be inconsistent with ordinary preference-satisfaction theory, or it will fail to recover sufficiently rich interpersonal well-being comparisons, or it will take on a number of other arguably odd and undesirable commitments.

Illness severity is a priority setting criterion in several countries. Age seems to matter when considering severity, but perhaps not small age differences. In the following article we consider Small Differences : small differences in age are not relevant when considering differential illness severity. We show that SD cannot be accommodated within utilitarian, prioritarian or egalitarian theories. Attempting to accommodate SD by postulating a threshold model becomes exceedingly complex and self-defeating. The only way to accommodate SD seems to be to (...) accept some form of relevance view, where some age differences are irrelevant. This view can accommodate SD, but at the expense of consistent priority orderings. Severity thus becomes unsuitable for systematic decision-making. We argue that SD should be dismissed and that we should accept a continuous relationship between severity of illness and age. (shrink)

In this paper, we argue that our moral concern for future well-being should reduce over time due to important practical considerations about how humans interact with spacetime. After surveying several of these considerations (around equality, special duties, existential contingency, and overlapping moral concern) we develop a set of core principles that can both explain their moral significance and highlight why this is inherently bound up with our relationship with spacetime. These relate to the equitable distribution of (1) moral concern in (...) a universe that we can only causally affect in one temporal direction; (2) access to the benefits from using spacetime as a resource; and (3) the burdens of care given (1) and (2). We conclude by considering the practical implications of our argument and find that, while it is often assumed that a preference for present over future well-being weakens the case for existential risk mitigation, this likely is not the case.

It may soon be possible for neurotechnology to connect two subjects' brains such that they share a single token mental state, such as a feeling of pleasure or displeasure. How will our moral frameworks have to adapt to accommodate this prospect? And if this sort of mental-state-sharing might already obtain in some cases, how should this possibility impact our moral thinking? This question turns out to be extremely challenging, because different examples generate different intuitions: If two subjects share very few (...) mental states, then it seems that we should count the value of those states twice, but if they share very many mental states, then it seems that we should count the value of those statesonce. We suggest that these conflicting intuitions can be reconciled if the mental states that matter for welfare have a holistic character, in a way that is independently plausible. We close by drawing tentative conclusions about how we ought to think about the moral significance of shared mental states. (shrink)

This paper examines a dilemma in reproductive and population ethics that can illuminate broader questions in axiology and normative ethics. This dilemma emerges because most people have conflicting intuitions concerning whether the interests of non-existent beings can outweigh the interests of existing beings when those merely potential beings are expected to have overall net-good or overall net-bad lives. The paper claims that the standard approach to this issue, in terms of exemplifying the conflict between Narrow Person-Affecting Views and Impersonal Views, (...) is not correct. It argues that, instead, we can approach the issue through the distinction between Symmetrical and Asymmetrical Views about the relative importance of positive and negative value. The paper also claims that Asymmetrical Views provide the most intuitively satisfactory solution to the dilemma and can in addition be defended independently on further grounds. Keywords: person-affecting views, impersonal views, symmetry, asymmetry. (shrink)

According to the Competing Claims View we decide between alternatives by looking at the competing claims held by affected individuals. The strength of these claims is a function of two features: how much they stand to benefit by each alternative, and how badly off they would be in its absence. The view can be, and is, endorsed by both egalitarians and prioritarians. For the former the second condition will concern looking at how badly off the person is relative to others, (...) whereas for the latter it will be how badly off she is in absolute terms. In this paper I want to argue that neither should be endorsed. The egalitarian version of CCV breaks down when attempting to assess the competing claims of possible persons who may never exist. Also, the view, on at least one plausible interpretation, leads to intransitive judgements. The prioritarian version of CCV, in turn, is vulnerable to its own unique objection, namely delivering an anti-prioritarian and rather implausible verdict in certain Single Person Cases. (shrink)
