This paper shows that versions of prioritarianism that focus at least partially on well-being levels at certain times conflict with conventional views of prudential value and prudential rationality. So-called timeslice prioritarianism, and pluralist views that ascribe importance to timeslices, hold that a benefit matters more, the worse off the beneficiary is at the time of receiving it. We show that views that evaluate outcomes in accordance with this idea entail that an agent who delays gratification makes an outcome worse, even (...) if it is better for the agent and worse for no one else. We take this to show that timeslice prioritarianism and some pluralist views violate Weak Pareto, and we argue that these versions of prioritarianism are implausible. (shrink)

Which individuals should count in a welfare-consequentialist analysis of public policy? Some answers to this question are parochial, and others are more inclusive. The most inclusive possible answer is ‘everybody to count for one.’ In other words, all individuals who are capable of having welfare – including foreigners, the unborn, and non-human animals – should be weighed equally. This article argues that ‘who should count’ is a question that requires a two-level answer. On the first level, a specification of welfare-consequentialism (...) serves as an ethical ideal, a claim about the attributes that the ideal policy would have. ‘Everybody to count for one’ might succeed on this level. However, on the second level is the welfare-consequentialist analysis procedure used by human analysts to give advice on real policy questions. For epistemic reasons, the analysis procedure should be more parochial than ‘everybody to count for one.’. (shrink)
