This thesis is about the moral reasons we have to do less than best. It consists of six chapters. Part I of the thesis proposes, extends, and defends reasons to do less than best. In Chapter One (“The Conditional Obligation”) I outline and reject two recent arguments from Joe Horton and Theron Pummer for the claim that we have a conditional obligation to bring about the most good. In Chapter Two (“Agglomeration and Agent-Relative Costs”) I argue that agent-relative costs can (...) justify permissions to less than best in a far greater range of decisions contexts than we currently believe. In Chapter Three (“Risk and Aggregation”) I discuss how anti-aggregative moral theories deal with risk, whilst proposing an argument in favour of ex-post moral theories. -/- In Part II of the thesis, I discuss longtermism, presenting a series of reasons to believe we have both significant permissions and obligations to prioritise those in the short-term. In Chapter Four (“Listening to Future People”) I criticise a recent argument presented by Andreas Mogensen for the claim we cannot have obligations grounded in the wellbeing of future people. I then show that, even permitting the existence of obligations to future people, we still have significant reasons to resist longtermism on the grounds of partiality. In Chapter Five (“The Complaints of Future People”) I argue that scepticism about aggregation is inconsistent with an obligation, or indeed even a permission, to help far future people. In Chapter Six (“Leaving the Present Behind”) I explore the moral significance of “dooming”, whilst arguing that we have a pro tanto reason of fairness to prioritise aiding those currently in existence.

We set out longtermist political philosophy as a research field by exploring the case for, and the implications of, ‘institutional longtermism’: the view that, when evaluating institutions, we should give significant weight to their very long-term effects. We begin by arguing that the standard case for longtermism may be more robust when applied to institutions than to individual actions or policies, both because institutions have large, broad, and long-term effects, and because institutional longtermism can plausibly sidestep various objections to individual (...) longtermism. We then address points of contact between longtermism and some central values of mainstream political philosophy, focusing on justice, equality, freedom, legitimacy, and democracy. While each value initially seems to conflict with institutional longtermism, we find that these conflicts are less clear-cut upon closer inspection, and that some political values might even provide independent support for institutional longtermism. We end with a grab bag of related questions that we lack space to explore here. (shrink)

The paper develops an account of the value of tradition that completes that of Samuel Scheffler and employs it to discuss whaling and bullfighting. The discussion, however, is applicable to many other practices the paper describes, and its relevance extends also beyond animal ethics. Some of the arguments discussed here for maintaining these traditions appeal to their positive aspects, such as their contribution to social or environmental harmony; other arguments focus on the impermissibility of one group criticizing another group’s practices (...) when its own are vulnerable to comparable criticism. Reflecting on the first kind of argument, the paper responds, building on the work of G. A. Cohen and T. M. Scanlon, that the value of tradition, if any, must be conditional. Reflecting on the second, however, the paper disagrees with Cohen and Scanlon on the impermissibility of casting the first stone. (shrink)

This paper looks at philosophical questions that arise in the context of AI alignment. It defends three propositions. First, normative and technical aspects of the AI alignment problem are interrelated, creating space for productive engagement between people working in both domains. Second, it is important to be clear about the goal of alignment. There are significant differences between AI that aligns with instructions, intentions, revealed preferences, ideal preferences, interests and values. A principle-based approach to AI alignment, which combines these elements (...) in a systematic way, has considerable advantages in this context. Third, the central challenge for theorists is not to identify ‘true’ moral principles for AI; rather, it is to identify fair principles for alignment that receive reflective endorsement despite widespread variation in people’s moral beliefs. The final part of the paper explores three ways in which fair principles for AI alignment could potentially be identified. (shrink)

We find meaning and value in our lives by engaging in everyday projects. But, according to a recent argument by Samuel Scheffler, this value doesn’t depend merely on what the projects are about. In many cases, it depends also on the future generations that will replace us. By imagining the imminent extinction of humanity soon after our own deaths, we can recognize both that much of our current valuing depends on a background confidence in the ongoing survival of humanity and (...) that the survival and flourishing of those future generations matters to us. After presenting Scheffler’s argument, I will explore two twentieth century precursors—Hans Morgenthau and Simone de Beauvoir—before returning to Scheffler to see that his argument can not only show us why future generations matter, but it can also give us hope for immortality and a blueprint for embracing a changing future.

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

How should we weigh suffering against happiness? This paper highlights the existence of an argument from intuitively plausible axiological principles to the striking conclusion that in comparing different populations, there exists some depth of suffering that cannot be compensated for by any measure of well-being. In addition to a number of structural principles, the argument relies on two key premises. The first is the contrary of the so-called Reverse Repugnant Conclusion. The second is a principle according to which the addition (...) of any population of lives with positive welfare levels makes the outcome worse if accompanied by sufficiently many lives that are not worth living. I consider whether we should accept the conclusion of the argument and what we may end up committed to if we do not, illustrating the implications of the conclusions for the question of whether suffering in aggregate outweighs happiness among human and non-human animals, now and in future.

According to the procreation asymmetry there is no moral reason to create a new and foreseeably happy person just because this person will be happy, but there is however a moral reason against creating a new and foreseeably unhappy person just because this person will be unhappy. A common way to defend this conjunction of claims is by employing a so-called existence-requirement, according to which the happiness of a given person p in a world w depends on it being possible (...) to understand p as an existing person in w. The aim of this paper is to consider whether this existence-requirement strategy is compatible with other intuitions and convictions held in normative moral theory and populations ethics. This aim will be achieved by considering whether the existence-requirement strategy is compatible with three plausible desiderata for a solution to the procreation asymmetry. Although some solutions to some potential incompatibilities are suggested, the thesis that will be argued for is that every instance of the existence-requirement strategy is incompatible with at least one of the relevant desiderata. Where the common denominating incompatibility for all instances of the existence-requirement strategy is to be found in an inability to be sufficiently action-guiding. (shrink)

When it comes to the metaethical task of explaining and making sense of what it is that we are doing while doing ethics, the subject of moral objectivity occupies an important and special place within that task. Thus, it is often agreed that being able to explain and justify the objective features of common moral practice is one of if not the most important task for any metaethical theory to undertake. In this dissertation, I tackle the issue of ethical objectivity (...) on behalf of metaethical constructivism. To be more precise, my aim is to make plausible, strengthen, and defend the constructivist original contribution to contemporary metaethics by developing a novel constructivist account on the objectivity of ethics. While the account that I develop herein presents a novel and independent approach to the subject of moral objectivity on behalf of constructivism, it also places itself between the two other positions within the constructivist camp that openly strive to secure ethical objectivity – namely Kantianism on the one hand, and the more recently developed Humean objectivist view on the other. It is for the latter reason that I call my own view the hybrid view. (shrink)

The purpose of this paper is to discuss the responsibility of AI experts for guiding the development of AI in a desirable direction. More specifically, the aim is to answer the following research question: To what extent are AI experts responsible in a forward-looking way for effects of AI technology that go beyond the immediate concerns of the programmer or designer? AI experts, in this paper conceptualised as experts regarding the technological aspects of AI, have knowledge and control of AI (...) technology that non-experts do not have. Drawing on responsibility theory, theories of the policy process, and critical algorithm studies, we discuss to what extent this capacity, and the positions that these experts have to influence the AI development, make AI experts responsible in a forward-looking sense for consequences of the use of AI technology. We conclude that, as a professional collective, AI experts, to some extent, are responsible in a forward-looking sense for consequences of use of AI technology that they could foresee, but with the risk of increased influence of AI experts at the expense of other actors. It is crucial that a diversity of actors is included in democratic processes on the future development of AI, but for this to be meaningful, AI experts need to take responsibility for how the AI technology they develop affects public deliberation.

The biosphere represents the global sum of all ecosystems. According to a prominent view in environmental ethics, ecocentrism, these ecosystems matter for their own sake, and not only because they contribute to human ends. As such, some ecocentrists are critical of the modern industrial civilization, and a few even argue that an irreversible collapse of the modern industrial civilization would be a good thing. However, taking a longer view and considering the eventual destruction of the biosphere by astronomical processes, we (...) argue that humans, a species with considerable technological know-how and industrial capacity could intervene to extend the lifespan of Earth’s biosphere, perhaps by several billion years. We argue that human civilization, despite its flaws and harmful impacts on many ecosystems, is the biosphere’s best hope of avoiding premature destruction. We argue that proponents of ecocentrism, even those who wholly disregard anthropocentric values, have a strong moral reason preserve the modern industrial civilization, for as long as needed to ensure biosphere survival.
