This volume collects selected papers delivered at the 15th Conference of the International Society for Utilitarian Studies, which was held at Karlsruhe Institute of Technology in July 2018. It includes papers dealing with the past, present, and future of utilitarianism – the theory that human happiness is the fundamental moral value – as well as on its applications to animal ethics, population ethics, and the future of humanity, among other topics.

Wellbeing describes how good life is for the person living it. Wellbeing comes in degrees. Subjective theories of wellbeing maintain that for objects or states of affairs to benefit us, we need to have a positive attitude towards these objects or states of affairs: the Resonance Constraint. In this article, we investigate to what extent subjectivism can plausibly account for degrees of wellbeing. There is a vast literature on whether preference-satisfaction theory – one particular subjective theory – can account for (...) degrees of wellbeing. This is generally taken to be problematic. However, other subjective theories – namely, desire-satisfaction, judgment- and value-fulfillment theories – do not suffer from the same difficulties. We introduce two models of degrees of wellbeing a subjectivist can employ: the Relative and the Absolute Model, and defend the claim that both models face difficulties. In particular, we argue that a subjectivist theory should describe instances of depression as instances of low degrees of wellbeing. We also argue that a reduction of desires may sometimes improve one’s degree of wellbeing, an idea we call the Epicurean Intuition. We then argue that the Relative Model fails to account for the disbenefit of certain types of depression, while the Absolute Model fails to meet a central commitment of subjectivism – the Resonance Constraint – and is unable to accommodate the Epicurean Intuition. The upshot of the paper is that subjectivist theories cannot account for degrees of well-being in a plausible way. (shrink)

The concept of well-being is increasingly gaining acceptance as an object of science, and many different types of well-being measures have been developed. A debate has emerged about which measures are able to capture well-being successfully. An important underlying problem is that there is no unified conceptual framework about the nature of well-being—a hotly debated topic of philosophical discussion. I argue that while there is little agreement about the nature of well-being in philosophy, there is an important agreement on some (...) important principles relevant for its measurement. I argue that well-being science has good reasons to accommodate these principles, but currently fails to do so. (shrink)

Human excellences such as intelligence, morality, and consciousness are investigated by philosophers as well as artificial intelligence researchers. One excellence that has not been widely discussed by AI researchers is practical wisdom, the highest human excellence, or the highest, seventh, stage in Dreyfus’s model of skill acquisition. In this paper, I explain why artificial wisdom matters and how artificial wisdom is possible (in principle and in practice) by responding to two philosophical challenges to building artificial wisdom systems. The result is (...) a conceptual framework that guides future research on creating artificial wisdom. (shrink)

In this paper I revisit an important response to the Moral Twin Earth (MTE) challenge: The Common Functional Role strategy (CFR). I argue that CFR is open to a revenge problem. MTE-cases allegedly show that two linguistic communities can be in genuine disagreement even when they are regulated by distinct families of properties. CFR provides a way to reconcile the intuition that the two communities are in genuine disagreement with the claim that the use of moral terms by both communities (...) is causally regulated by different families of properties. This is done by identifying a functional role that those families of properties both fulfill. Still, even if CFR is successful, its proponents need to face a serious revenge problem. Roughly, it could be that the families of properties that regulate each community are equally perfect realizers of the relevant higher-order functional state. I suggest that the proponent of CFR faces a dilemma: either CFR has controversial implications about first-order moral theory, or CFR needs to be coupled with substantive and parochial empirical/metaphysical assumptions to avoid those implications.

A review of _Wittgenstein’s Moral Thought,_ edited by Reshef Adam-Segal and Edmund Dain.

What, if anything, directly detracts from well-being? Objective list theorists affirm basic goods such as knowledge, friendship, and achievement, but it is less clear what they should say about opposing bads. In this paper, I argue that false beliefs, unhealthy relationships, and failed projects are not basic bads and do not directly detract from well-being. They can have bad effects or elements, or block the realization of basic goods, but do not themselves carry negative weight with respect to well-being. This (...) is shown by comparing cases where these bads are present and absent, examining their relation to negative overall well-being, and considering the role of these bads in the pursuit of positive goods.

G. A. Cohen has argued that there is a surprising truth in conservatism—namely, that there is a reason for some valuable things to be preserved, even if they could be replaced with other, more valuable things. This conservative thesis is motivated, Cohen suggests, by our judgments about a range of hypothetical cases. After reconstructing Cohen's conservative thesis, I argue that the relevant judgments about these cases do not favor the conservative thesis over standard, nonconservative axiological views. But I then argue (...) that there is a Mirrored Histories case that is such that, if one shares Cohen's conservative attitude, judgments about this case favor Cohen's conservative thesis over a wide range of non-conservative axiological views. Reflection on this case also suggests a different explanation of apparently conservative judgments that merits consideration in its own right. (shrink)

Various social epistemologists employ what seem to be rather distinct notions of group rationality. In this essay, I offer an account of group rationality that is able to unify the dominant notions present in the literature under a single framework. I argue that if we employ a teleological account of epistemic rationality, and then allow that there are many different epistemic goals that are worth pursuing for various groups and individuals, we can then see how those seemingly divergent understandings of (...) group rationality are all intimately related. I close by showing how the view has the additional benefit of allowing us to generate practical, normative suggestions for groups in the real world. (shrink)

Following Moore, value invariabilists deny that the intrinsic value of something can be affected by features extrinsic to it. The primary focuses of this paper are (i) to examine the invariabilistic thesis and expand upon how we ought to understand it, in light of contemporary axiological distinctions, and (ii) to argue that distinguishing between different kinds of invariabilism provides resources to undermine a prominent argument against variabilism. First, I use two contemporary axiological distinctions to clarify what kind of value the (...) invariabilism debate concerns (final value). Then I show how the distinction between personal value and value simpliciter reveals different variabilistic theses, depending on what type of final value one thinks may be affected by extrinsic features. Using this insight, I challenge an argument for final value simpliciter invariabilism. Variabilists offer the example of the vicious being pleased as a counterexample to the claim that pleasure’s final value is invariant to contextual changes. The argument that I examine purports to show that this case actually supports invariabilism about pleasure’s final value simpliciter, because the best explanation for why the vicious being pleased is a fitting object of indignation is that the vicious person’s pleasure is finally valuable simpliciter. I argue that this argument fails because the vicious person’s pleasure being finally personally good for them better explains why an attitude of indignation is fitting. I address two objections and conclude with remarks about how my results might inform future research on value invariabilism. (shrink)

This paper argues that the Lockean proviso can be utilized as a relevant principle of justice for food security under global climate change. Since reducing GHG emissions is key to enhancing food security, we suggest a global food security scheme that systematically allots, among all people, access to GHG sinks in food systems impacted by global climate change. For consideration of the scheme, it is important to have a principle of justice. Furthermore, it should incorporate the value of fairness. A (...) relevant principle of climate justice for food security should meet the following criteria: (1) the parties concerned under the scheme are states; (2) fairness does not undermine the requirement that the basic needs of all people must be met; (3) when determining fair burdens, a fair distribution of the rights to use GHG sinks should be sensitive both to each state’s responsibility for its GHG emissions and to (4) each state’s effort to reduce such emissions. With them in mind, first, we argue that the Lockean proviso can provide legitimate guidance for each state. Second, the Lockean proviso reasonably enjoins that a state has a right to a food system that secures its citizens’ basic needs, and a duty to meet the basic needs of other people. Third, the Lockean proviso can be deployed as a principle of both global justice and intergenerational justice for food security. Finally, the Lockean proviso enables us to count the reduction of GHG emissions by each state as “the fruits of its labors”. (shrink)

Overview of the main issues about value pluralism.

In this thesis, I discuss the aggregation problem for T. M. Scanlon’s “contractualism”. I argue that Scanlonian contractualists have the following two options when it comes to the aggregation problem. First, they can choose to limit aggregation directly via a specific version of the Relevance View, “Sequential Claims-Matching”. Second, Scanlonian contractualists can adopt a so-called “mixed solution” of which I propose a specific version. My mixed solution does not limit aggregation. Rather, it either avoids some of the counterintuitive results in (...) certain cases, or at least makes these same results look a lot less counterintuitive by putting them into perspective thanks to a plausible plurality of precisely specified values. The stakes between these two options are as follows. The first option justifies Scanlon’s intuition in one vs. many cases of which his “World Cup Case” is one example, but it comes at the cost of a seemingly quite limited range of application: any version of the Relevance View only works in cases in which we have no more than two groups of competing claimants. The second option has the exact opposite implications: my mixed solution cannot justify Scanlon’s intuition in one vs. many cases, but it could be applied to any case with any number of groups of competing claimants. In this choice between pre-theoretical intuition and feasibility, I would urge Scanlonian contractualists to choose feasibility. (shrink)
