This thesis consists of several independent papers in population ethics. I begin in Chapter 1 by critiquing some well-known 'impossibility theorems', which purport to show there can be no intuitively satisfactory population axiology. I identify axiological vagueness as a promising way to escape or at least mitigate the effects of these theorems. In particular, in Chapter 2, I argue that certain of the impossibility theorems have little more dialectical force than sorites arguments do. From these negative arguments I move to (...) positive ones. In Chapter 3, I justify the use of a 'veil of ignorance', starting from three more basic normative principles. This leads to positive arguments for various kinds of utilitarianism - the best such arguments I know. But in general the implications of the veil depend on how one answers what I call 'the risky existential question': what is the value to an individual of a chance of non-existence? I chart out the main options, and raise some puzzles for non-comparativism, the view that life is incomparable to non-existence. Finally, in Chapter 4, I consider the consequences for population ethics of the idea that what is normatively relevant is not personal identity, but a degreed relation of psychological connectedness. In particular, I pursue a strategy based in population ethics for understanding the controversial 'time-relative interests' account of the badness of death. (shrink)

Regan appeals to the benefit of the doubt as a reason to include some animals within the scope of his arguments about the rights of animals. I think the informal appeal to the benefit of the doubt can be fleshed out and made more compelling. What I shall do differs from his project, however. It is narrower in scope, because I shall focus on a single issue, the dietary use of animals. On another dimension, though, I aim to do more. (...) Regan thinks that it is “not unreasonable” to extend the benefit of the doubt, and that it is better to do so. I shall be arguing that it is unreasonable not to do so. (shrink)

Immortality—living forever and avoiding death—seems to many to be desirable. But is it? It has been argued that an immortal life would fairly soon become boring, trivial, and meaningless, and is not at all the sort of thing that any of us should want. Yet boredom and triviality presuppose our having powerful memories and imaginations, and an inability either to shake off the past or to free ourselves of weighty visions of the future. Suppose, though, that our capacities here are (...) limited, so that our temporal reach is fairly significantly constrained. Then, I argue, these alleged problems with immortality will recede. Moreover, similar limitations might help us in the actual world, where life is short. If we cannot see clearly to its end points, both ahead and behind, life will seem longer. (shrink)

Over the past century, animal agriculture in the United States has transformed from a system of small, family farms to a largely industrialized model—often known as ‘industrial farm animal production’ (IFAP). This model has successfully produced a large supply of cheap meat, eggs and dairy products, but at significant costs to animal welfare, the environment, the risk of zoonotic disease, the economic and social health of rural communities, and overall food abundance. Over the past 40 years, numerous critiques of IFAP (...) have been published, for both academic and non-academic audiences, mostly focusing on our obligations to animals. Here we offer a comprehensive critique of IFAP, focusing not only on our obligations to animals, but also important environmental, social, economic, and public health concerns. Our cumulative argument proceeds in five steps: (1) we briefly review the structure and key characteristics of IFAP; (2) we review the adverse effects of IFAP; (3) we review the historical development and positive rationale for IFAP; (4) we summarize previous moral critiques of IFAP, as well as defenses of it; and (5) we offer a moral critique of IFAP based on the common morality, and in particular on a principle of nonmaleficence, which we take to be the least controversial argument.

One important trend in political philosophy is to hold that non-human animals don't directly place demands of justice on us. Another important trend is to give considerations of justice normative priority in our general normative theorising about social/political institutions. This situation is problematic, given the actual ethical standing of non-human animals. Either we need a theory of justice that gives facts about non-human animals a non-derivative explanatory role in the determination of facts about what justice involves, or else we should (...) be wary of the default normative priority that considerations of justice have in much of contemporary political philosophy. This discussion brings out important general methodological points tied to the role of concept and word choice in normative theorising about our social/political institutions. These methodological points, I argue, matter for a range of discussions in contemporary political philosophy, including those about global justice. (shrink)

This paper takes up Axel Honneth’s suggestion that we, in the 21st century Western world, should revisit the Marxian idea of reification; unlike Honneth, however, this paper applies reification to the ways in which humans relate to non-human animals, particularly in the context of scientific experiments. Thinking about these practices through the lens of reification, the paper argues, yields a more helpful understanding of what is regarded as problematic in those practices than the standard animal rights approaches. The second part (...) of the paper offers ways of overcoming reification that go beyond Honneth’s idea of recognition by introducing Iris Murdoch’s idea of attention. This proposed strategy makes the ethical relevance of reification more salient and makes it possible to counter reification through a practice such as attention which, unlike recognition, can be consciously established.

It is generally assumed that humans are the only animals who can possess a concept of death. However, the ubiquity of death in nature and the evolutionary advantages that would come with an understanding of death provide two prima facie reasons for doubting this assumption. In this paper, my intention is not to defend that animals of this or that nonhuman species possess a concept of death, but rather to examine how we could go about empirically determining whether animals can (...) have a concept of death. In order to answer this question, I begin by sketching an account of concept possession that favours intensional classification rather than mere extensional discrimination. Further, I argue that the concept of death should be construed as neither binary nor universal. I then present a proposal for a set of minimal conditions that must be met to have a concept of death. I argue that having a minimal understanding of death entails first expecting a dead individual to be alive, and then grasping its non-functionality and irreversibility. Lastly, I lay out the sort of observational and experimental evidence that we should look for to determine whether animals have the capacity for a minimal comprehension of death. (shrink)

This paper provides an account of the Aristotelian virtue of temperance in regards to food, an account that revolves around the idea of enjoying the right objects and not enjoying the wrong ones. In doing so, the paper distinguishes between two meanings of “taking pleasure in something,” one that refers to the idea of the activity and one to the experience of the activity. The paper then connects this distinction to the temperate person’s attitude towards enjoying the right things and (...) to hitting the mean by enjoying the right object, at the right time, and so on. Throughout, the paper uses eating meat as a case in point, to both illustrate and inform the discussion. In the penultimate section, the paper argues that temperance admits of various conceptions depending on what is right and wrong in regards to eating meat. The paper concludes by responding to three objections. (shrink)

The risks of harm to nonhuman primates, and the absence of benefits for them, are critically important to decisions about nonhuman primate research. Current guidelines for review and practice tend to be permissive for nonhuman primate research as long as minimal welfare requirements are fulfilled and human medical advances are anticipated. This situation is substantially different from human research, in which risks of harms to the individual subject are typically reduced to the extent feasible. A risk threshold is needed for (...) the justification of research on nonhuman primates, comparable to the way risk thresholds are set for vulnerable human subjects who cannot provide informed consent. Much of the laboratory research conducted today has inadequate standards, leading to common physical, psychological, and social harms. (shrink)
