Here, we argue for a mathematical equation that captures desert. Our procedure consists of setting out principles that a correct equation must satisfy and then arguing that our set of equations satisfies them. We then consider two objections to the equation. First, an objector might argue that desert and well-being separately contribute to intrinsic goodness, and they do not separately contribute. The concern here is that our equations treat them as separate contributors. Second, our set of desert-equations are unlike equations (...) in science because our equations involve multiple desert-equations with the applicable equation depending on how the variables are filled out. Neither objection succeeds. (shrink)

This paper is about the role of interpersonal comparisons in Harsanyi's aggregation theorem. Harsanyi interpreted his theorem to show that a broadly utilitarian theory of distribution must be true even if there are no interpersonal comparisons of well-being. How is this possible? The orthodox view is that it is not. Some argue that the interpersonal comparability of well-being is hidden in Harsanyi's premises. Others argue that it is a surprising conclusion of Harsanyi's theorem, which is not presupposed by any one (...) of the premises. I argue instead that Harsanyi was right: his theorem and its weighted-utilitarian conclusion do not require interpersonal comparisons of well-being. The key to making sense of this possibility is to treat Harsanyi's weights as dimensional constants rather than dimensionless numbers. (shrink)

In Manipulated Agents: A Window to Moral Responsibility, Alfred Mele invokes radical reversal cases in which one agent is covertly manipulated to be just like another agent in relevant respects to defend a version of the following “externalist” thesis: how agents acquire their springs of action, such as desires and beliefs, bears on whether they are morally responsible for their actions. I assess proposed rationales for the crucial verdict that agents in such cases are not responsible for their germane actions. (...) I argue for the superiority of Mele’s rationale and propose that these cases also support accepting an externalist constraint on other normative appraisals, such as those of practical rationality. Key words: Moral obligation; practical rationality; radical reversal cases; ultimate origination; zygote argument. (shrink)

Matthew Adler's Measuring Social Welfare is an introduction to the social welfare function (SWF) methodology. This essay questions some ideas at the core of the SWF methodology having to do with the relation between the SWF and the measure of well-being. The facts about individual well-being do not single out a particular scale on which well-being must be measured. As with physical quantities, there are multiple scales that can be used to represent the same information about well-being; no one scale (...) is special. Like physical laws, the SWF and its ranking of distributions cannot depend on exactly which of these scales we use. Adler and other theorists in the SWF tradition have used this idea to derive highly restrictive constraints on the shape of the SWF. These constraints rule out seemingly plausible views about distributive justice and population ethics. I argue, however, that these constraints stem from a simple but instructive mistake. The SWF should not be applied to vectors of numbers such as 1 and 2, but rather to vectors of dimensioned quantities such as 1 util and 2 utils. This seemingly pedantic suggestion turns out to have far-reaching consequences. Unlike the orthodox SWF approach, treating welfare levels as dimensioned quantities lets us distinguish between real changes in well-being and mere changes in the unit of measurement. It does this without making the SWF depend on the scale on which welfare is measured, and in a way that avoids the restrictive constraints on the shape of the SWF. (shrink)

This article seeks to cause trouble for a brand of consequentialism known as ‘desertarianism’. In somewhat different ways, views of this kind evaluate outcomes more favourably, other things equal, the better the fit between the welfare different people enjoy and the welfare they each deserve. These views imply that we can improve outcomes by redistributing welfare to fit desert, which seems plausible enough. Unfortunately, they also imply that we can improve outcomes by redistributing desert to fit welfare: in other words, (...) by making happy people more deserving, at the cost of making unhappy people less deserving. Extant versions of desertarianism predict that such ‘deservingness transfers’ are improvements and that we ought to carry them out. Even worse, they will sometimes rank deservingness transfers higher than simply benefitting deserving people who are poorly off. (shrink)

I argue that, each of the following, appropriately clarified to yield a noteworthy thesis, is true. Moral obligation can affect moral responsibility. Obligation succumbs to changes in responsibility. Obligation is immune from changes in responsibility.

A standard criticism of act-utilitarianism is that it is only indirectly concerned with the distribution of welfare between individuals and, therefore, does not take adequate account of the separateness between individuals. In response a number of philosophers have argued that act-utilitarianism is only vulnerable to that objection because it adheres to a theory of the good which ignores non-welfarist sources of intrinsic value such as justice. Fred Feldman, for example, argues that intrinsic value is independently generated by the receipt of (...) welfare and the degree to which receipt accords with the demands of justice, and that an action is right insofar as it maximizes the sum of both those sources of value. In response it is argued that justicized consequentialism only blocks the objection at the expense of presupposing deontological constraints. In addition, it is argued that the value of justice cannot be explained non-deontically and, therefore, that the proposed theory is not consequentialist all the way down. (shrink)
