It is widely agreed that because animals feel pain we should not make them suffer gratuitously. Some ethical theories go even further: because of the capacities that they possess, animals have the right not to be harmed or killed. These views concern what not to do to animals, but we also face questions about when we should, and should not, assist animals that are hungry or distressed. Should we feed a starving stray kitten? And if so, does this commit us, (...) if we are to be consistent, to feeding wild animals during a hard winter? In this controversial book, Clare Palmer advances a theory that claims, with respect to assisting animals, that what is owed to one is not necessarily owed to all, even if animals share similar psychological capacities. Context, history, and relation can be critical ethical factors. If animals live independently in the wild, their fate is not any of our moral business. Yet if humans create dependent animals, or destroy their habitats, we may have a responsibility to assist them. Such arguments are familiar in human cases-we think that parents have special obligations to their children, for example, or that some groups owe reparations to others. Palmer develops such relational concerns in the context of wild animals, domesticated animals, and urban scavengers, arguing that different contexts can create different moral relationships.

Drawing heavily on recent empirical research to update R.M. Hare's two-level utilitarianism and expand Hare's treatment of "intuitive level rules," Gary Varner considers in detail the theory's application to animals while arguing that Hare should have recognized a hierarchy of persons, near-persons, & the merely sentient.

For many people "animal rights" suggests campaigns against factory farms, vivisection or other aspects of our woeful treatment of animals. Zoopolis moves beyond this familiar terrain, focusing not on what we must stop doing to animals, but on how we can establish positive and just relationships with different types of animals.

This essay argues that non-linguistic animals qualify not just for externalist notions of rationality (maximizing biological fitness or utility), but also for internal ones. They can act for reasons in several senses: their behaviour is subject to intentional explanations, they can act in the light of reasons - provided that the latter are conceived as objective facts rather than subjective mental states - and they can deliberate. Finally, even if they could not, it would still be misguided to maintain that (...) animals are capable only of (mechanical) behaviour, not of (intentional) action. (shrink)

In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

The influential account of contractualist moral theory offered recently by T. M. Scanlon in What We Owe to Each Other is not intended to account for all the various moral commitments that people have; it covers only a narrow—though important—range of properly moral concerns and claims. Scanlon focuses on what he calls the morality of right and wrong or, as he puts it in his title, what we owe to each other. The question arises as to whether nonhuman animals can (...) be wronged in the narrow sense of a moral wrong with which contractualism is concerned. Can we owe things to nonhuman animals? Scanlon is sensitive to the importance of this question, but he ultimately favors an account in which the perspectives of nonhuman animals are not explicitly included in contractualist theorizing. Nevertheless, it appears that contractualism, largely as Scanlon conceives it, can accommodate duties to nonhuman animals. Moreover, if contractualism cannot make this accommodation, then its status as a theory that answers to important common-sense moral intuitions becomes questionable in ways that extend beyond its failure to live up to intuitions many share about the status of nonhuman animals.

Utility, rights, and holistic standards all point toward some modest steps to limit or check the predatory activity of carnivores relative to their victims. At the very least, we should limit current subsidies to nature’s carnivores. Policing nature need not be absurdly costly or violate common-sense intuitions.

In the subsequent pages, I want to develop a distinction between wanting and valuing which will enable the familiar view of freedom to make sense of the notion of an unfree action. The contention will be that, in the case of actions that are unfree, the agent is unable to get what he most wants, or values, and this inability is due to his own "motivational system." In this case the obstruction to the action that he most wants to do (...) is his own will. It is in this respect that the action is unfree: the agent is obstructed in and by the very performance of the action. (shrink)

It is my view that one essential difference between persons and other creatures is to be found in the structure of a person's will. Besides wanting and choosing and being moved to do this or that, men may also want to have certain desires and motives. They are capable of wanting to be different, in their preferences and purposes, from what they are. Many animals appear to have the capacity for what I shall call "first-order desires" or "desires of the (...) first order," which are simply desires to do or not to do one thing or another. No animal other than man, however, appears to have the capacity for reflective self-evaluation that is manifested in the formation of second-order desires. (shrink)

In this essay, I argue that contractualism, even when it is actually used to construe our moral duties towards non-human animals, does not do so naturally. We can infer from our experiences with companion animals that we owe moral duties to them because of special relationships we are in with them. We can further abstract that we owe general moral duties to non-human animals because they are the kinds of beings that we can have relationships with, and because of the (...) capacities that make possible this relational capacity. This type of approach better explains our duties to non-human animals and other non-rational beings than does the trustee account that Scanlon leaves room for in his contractualism. (shrink)

Animals suffer harms not only in human captivity but in the wild as well. Some of these latter harms are due to humans, but many of them are not. Consider, for example, the harms of predation, i.e. of being hunted, killed, and eaten by other animals. Should we intervene in nature to prevent these harms? In this article, I consider two possible ways in which we might do so: (1) by herbivorising predators (i.e. genetically modify them so that their offspring (...) gradually evolve into herbivores) and (2) by painlessly killing predators. I argue that, among these options, painlessly killing predators would be preferable to herbivorising them. I then argue that painlessly killing predators, despite its costs to predators, might under certain circumstances be justifiable. (shrink)

Consequentialism is thought to be in significant conflict with animal rights theory because it does not regard activities such as confinement, killing, and exploitation as in principle morally wrong. Proponents of the “Logic of the Larder” argue that consequentialism results in an implausibly pro-exploitation stance, permitting us to eat farmed animals with positive well- being to ensure future such animals exist. Proponents of the “Logic of the Logger” argue that consequentialism results in an implausibly anti-conservationist stance, permitting us to exterminate (...) wild animals with negative well-being to ensure future such animals do not exist. We argue that this conflict is overstated. Once we have properly accounted for indirect effects, such as the role that our policies play in shaping moral attitudes and behavior and the importance of accepting policies that are robust against deviation, we can see that consequentialism may converge with animal rights theory significantly, even if not entirely.

"Political Ideas in the Twentieth Century", Historical Inevitability", "Two Concepts of Liberty", "John Stuart Mill and the Ends of Life". These four essays deal with the various aspects of individual liberty, including the distinction between positive and negative liberty and the necessity of rejecting determinism if we wish to keep hold of the notions of human responsibility and freedom.

In this paper, I aim to show that agency-based accounts of moral status are more plausible than many have previously thought. I do this by developing a novel account of moral status that takes agency, understood as the capacity for intentional action, to be the necessary and sufficient condition for the possession of moral status. This account also suggests that the capacities required for sentience entail the possession of agency, and the capacities required for agency, entail the possession of sentience. (...) Thus on this account sentient beings possess agency and agents possess sentience. If this is correct, it will show that an Agency Account of moral status can offer a plausible defence of the moral status of all sentient beings, something that previous Agency Accounts have not succeeded in doing. What is more, this account could establish that all sentient animals are not just moral status holders per se, but that they are owed pro tanto obligations regarding continued existence and liberty, similar in kind, though not always in strength, to those owed to humans.

There is now widespread agreement that many non-human animals are sentient, and that this fact has important moral and political implications. This book is devoted to sketching what this 'sentientist politics' might look like.

This book is in three sections, with two chapters in each. It begins with questions of psychology: questions to do with what it means to be an intentional agent and, in particular, what it means to be an agent with the capacity for thought. Having sketched an overall view of the intentional, thinking agent, it then goes on to explore the difference that social life makes to the mentality of such agents; in effect, it outlines a social ontology. And, having (...) developed a picture of the mind in society – of the common or social mind – it turns, finally, to the lessons of this picture for the pursuit of social and political theory: for the explanation of what happens on the social scene and for the evaluation of the different ways in which that scene may be structured.

Wild animal reproduction poses an important moral problem for animal rights theorists. Many wild animals give birth to large numbers of uncared-for offspring, and thus child mortality rates are far higher in nature than they are among human beings. In light of this reproductive strategy – traditionally referred to as the ‘r-strategy’ – does concern for the interests of wild animals require us to intervene in nature? In this paper, I argue that animal rights theorists should embrace fallibility-constrained interventionism: the (...) view that intervention in nature is desirable but should be constrained by our ignorance of the inner workings of ecosystems. Though authors sometimes assume that large-scale intervention requires turning nature into an enormous zoo, I suggest an alternative. With sufficient research, a new form of gene editing called CRISPR promises to one day give us the capacity to intervene without perpetually interfering with wild animals’ liberties. (shrink)

Theories of social justice are necessarily abstract, reaching beyond the particular and the immediate to the general and the timeless. Yet such theories, addressing the world and its problems, must respond to the real and changing dilemmas of the day. A brilliant work of practical philosophy, Frontiers of Justice is dedicated to this proposition. Taking up three urgent problems of social justice neglected by current theories and thus harder to tackle in practical terms and everyday life, Martha Nussbaum seeks a (...) theory of social justice that can guide us to a richer, more responsive approach to social cooperation. The idea of the social contract--especially as developed in the work of John Rawls--is one of the most powerful approaches to social justice in the Western tradition. But as Nussbaum demonstrates, even Rawls's theory, suggesting a contract for mutual advantage among approximate equals, cannot address questions of social justice posed by unequal parties. How, for instance, can we extend the equal rights of citizenship--education, health care, political rights and liberties--to those with physical and mental disabilities? How can we extend justice and dignified life conditions to all citizens of the world? And how, finally, can we bring our treatment of nonhuman animals into our notions of social justice? Exploring the limitations of the social contract in these three areas, Nussbaum devises an alternative theory based on the idea of capabilities. She helps us to think more clearly about the purposes of political cooperation and the nature of political principles--and to look to a future of greater justice for all. (shrink)

In Freedom Within Reason, Susan Wolf charts a course between incompatibilism, or the notion that freedom and responsibility require causal and metaphysical independence from the impersonal forces of nature, and compatibilism, or the notion that people are free and responsible as long as their actions are governed by their desires. Wolf argues that some of the forces which are beyond our control are friends to freedom rather than enemies of it, enabling us to see the world for what it is. (...) The freedom we want is not independence from the world, but independence from the forces that prevent us from choosing how to live in the light of a sufficient appreciation of the world. (shrink)

This book provides a comprehensive, systematic theory of moral responsibility. The authors explore the conditions under which individuals are morally responsible for actions, omissions, consequences, and emotions. The leading idea in the book is that moral responsibility is based on 'guidance control'. This control has two components: the mechanism that issues in the relevant behavior must be the agent's own mechanism, and it must be appropriately responsive to reasons. The book develops an account of both components. The authors go on (...) to offer a sustained defense of the thesis that moral responsibility is compatible with causal determinism. (shrink)

Utilitarianism, the great reforming philosophy of the nineteenth century, has today acquired the reputation for being a crassly calculating, impersonal philosophy unfit to serve as a guide to moral conduct. Yet what may disqualify utilitarianism as a personal philosophy makes it an eminently suitable guide for public officials in the pursuit of their professional responsibilities. Robert E. Goodin, a philosopher with many books on political theory, public policy and applied ethics to his credit, defends utilitarianism against its critics and shows (...) how it can be applied most effectively over a wide range of public policies. In discussions of such issues as paternalism, social welfare policy, international ethics, nuclear armaments, and international responses to the environment crisis, he demonstrates what a flexible tool his brand of utilitarianism can be in confronting the dilemmas of public policy in the real world.

What are appropriate criteria for assessing a theory of morality? In Ideal Code, Real World, Brad Hooker begins by answering this question, and then argues for a rule-consequentialist theory. According to rule-consequentialism, acts should be assessed morally in terms of impartially justified rules, and rules are impartially justified if and only if the expected overall value of their general internalization is at least as great as for any alternative rules. In the course of developing his rule-consequentialism, Hooker discusses impartiality, well-being, (...) fairness, equality, the question of how the 'general internalization' of rules is to be interpreted by rule-consequentialism, and the main objections to rule-consequentialism. He also discusses the social contract theory of morality, act-consequentialism, and the question of which moral prohibitions and which duties to help others rule-consequentialism endorses. The last part of the book considers the implications of rule-consequentialism for some current controversies in practical ethics. (shrink)

Freedom is sometimes cast as the psychological ideal that distinguishes human beings from other animals; sometimes as the ethical ideal that distinguishes some human beings from others; and sometimes as the political ideal that distinguishes some human societies from others. This paper is an attempt to put the three ideals in a common frame, revealing their mutual connections and differences.

This study builds on the work of contemporary civic republicans, supplying a detailed analysis of the concept of domination absent in the familiar accounts of political freedom as non-domination.

Welfare biology is the study of living things and their environment with respect to their welfare. Despite difficulties of ascertaining and measuring welfare and relevancy to normative issues, welfare biology is a positive science. Evolutionary economics and population dynamics are used to help answer basic questions in welfare biology : Which species are affective sentients capable of welfare? Do they enjoy positive or negative welfare? Can their welfare be dramatically increased? Under plausible axioms, all conscious species are plastic and all (...) plastic species are conscious. More complex niches favour the evolution of more rational species. Evolutionary economics also supports the common-sense view that individual sentients failing to survive to mate suffer negative welfare. A kind of God-made fairness between species is also unexpectedly found. The contrast between growth maximization, average welfare, and total welfare maximization is discussed. It is shown that welfare could be increased without even sacrificing numbers. Since the long-term reduction in animal suffering depends on scientific advances, strict restrictions on animal experimentation may be counter-productive to animal welfare. (shrink)

How do we judge whether an action is morally right or wrong? If an action is wrong, what reason does that give us not to do it? Why should we give such reasons priority over our other concerns and values? In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other. According to his contractualist view, thinking about right and wrong is thinking (...) about what we do in terms that could be justified to others and that they could not reasonably reject. He shows how the special authority of conclusions about right and wrong arises from the value of being related to others in this way, and he shows how familiar moral ideas such as fairness and responsibility can be understood through their role in this process of mutual justification and criticism. Scanlon bases his contractualism on a broader account of reasons, value, and individual well-being that challenges standard views about these crucial notions. He argues that desires do not provide us with reasons, that states of affairs are not the primary bearers of value, and that well-being is not as important for rational decision-making as it is commonly held to be. Scanlon is a pluralist about both moral and non-moral values. He argues that, taking this plurality of values into account, contractualism allows for most of the variability in moral requirements that relativists have claimed, while still accounting for the full force of our judgments of right and wrong.

Most nonhuman animals live on the terms imposed on them by human beings. This condition of being under the mastery of another, or domination, is what republicanism identifies as political unfreedom. Yet there are several problems that must be solved in order to successfully extend republicanism to animals. Here I focus on the question of whether freedom can be a benefit for individuals without a free will. I argue that once we understand the grounds that make freedom a desirable property (...) of choices, we can see how it is appropriate to predicate it of those made by any sentient agent. (shrink)

In Zoopolis, Donaldson and Kymlicka argue that intervention in nature to aid animals is sometimes permissible, and in some cases obligatory, to save them from the harms they commonly face. But they claim these interventions must have some limits, since they could otherwise disrupt the structure of the communities wild animals form, which should be respected as sovereign ones. These claims are based on the widespread assumption that ecosystemic processes ensure that animals have good lives in nature. However, this assumption (...) is, unfortunately, totally unrealistic. Most animals are r-strategists who die in pain shortly after coming into existence, and those who make it to maturity commonly suffer terrible harms too. In addition, most animals do not form the political communities Zoopolis describes. The situation of animals in the wild can therefore be considered analogous to one of humanitarian catastrophe, or to that of irretrievably failed states. It matches closely what a Hobbesian state of nature would be like. This means that intervention in nature to aid nonhuman animals should not be limited as Donaldson and Kymlicka argue. (shrink)

Sentience is the capacity to have feelings, such as feelings of pain, pleasure, hunger, thirst, warmth, joy, comfort and excitement. It is not simply the capacity to feel pain, but feelings of pain, distress or harm, broadly understood, have a special significance for animal welfare law. Drawing on over 300 scientific studies, we evaluate the evidence of sentience in two groups of invertebrate animals: the cephalopod molluscs or, for short, cephalopods (including octopods, squid and cuttlefish) and the decapod crustaceans or, (...) for short, decapods (including crabs, lobsters and crayfish). We also evaluate the potential welfare implications of current commercial practices involving these animals. (shrink)

The prevalent views of animal liberty among animal advocates suggest that liberty is merely instrumentally valuable and invasive paternalism is justified. In contrast to this popular view, I argue that liberty is intrinsically good for animals. I suggest that animal well-being is best accommodated by an Objective List Theory and that liberty is an irreducible component of animal well-being. As such, I argue that it is good for animals to possess liberty even if possessing liberty does not contribute towards their (...) subjective well-being, and even in some cases where it has a negative effect upon their subjective well-being. To establish this view I argue that if animals are agents, as I assume they are, then like humans they must be able to determine the course of their own lives (to some extent). Further, having the opportunity to self-determine one’s life just is the very same thing as liberty, and having the opportunity to determine the course of one’s life is intrinsically good. Thus liberty has intrinsic value for humans and animals. So, in addition to the instrumental harms of having one’s liberty restricted, I claim that restricting animals’ liberty in principle harms them because it undermines their capacity for self-determination and fails to acknowledge their authority as agents to make their own choices.

Can animals be persons? Scientific and philosophical consensus supplies a resounding, 'No!' In this book, Mark Rowlands disagrees. Not only can animals be persons, many of them probably are. A person is an individual in which consciousness, rationality, self-awareness and other-awareness converge, and many animals are such individuals.

Animal ethics has received a lot of attention over the last four decades. Its focus, however, has almost exclusively been on the welfare of captive animals, ignoring the vast majority of animals: those living in the wild. I suggest that this one-sided focus is unwarranted. On the empirical side, I argue that wild animals overwhelmingly outnumber captive animals, and that billions of wild animals are likely to have lives that are even more painful and distressing than those of their captive (...) counterparts. On the normative side, I argue that as long as we have duties of assistance towards humans suffering from natural causes, and we reject anthropocentrism, we also have duties of assistance towards animals suffering in the wild.Article first published online: 22 MARCH 2016.

Though the revised edition of A Theory of Justice, published in 1999, is the definitive statement of Rawls's view, so much of the extensive literature on Rawls's theory refers to the first edition. This reissue makes the first edition once again available for scholars and serious students of Rawls's work.

The moral consideration of nonhuman animals and the critique of speciesism have been defended by appeal to a variety of ethical theories. One of the main approaches in moral and political philosophy today from which to launch such a defense is egalitarianism, which is the view that we should aim at favoring the worse off by reducing inequality. This paper explains what egalitarianism is and shows the important practical consequences it has for nonhuman animals, both those that are exploited by (...) humans and those in need of aid in the wild. Egalitarianism implies rejecting speciesism, and in practice it prescribes ceasing to exploit nonhuman animals as well as assisting them. Moreover, because they are worse off in comparison to humans, egalitarianism prescribes giving priority to the interests nonhuman animals. Due to this, egalitarianism gives us extra reasons to defend them beyond those entailed by other nonspeciesist approaches. (shrink)

According to our traditional conception of agency, most human beings are agents and most, if not all, nonhuman animals are not. However, recent developments in philosophy and psychology have made it clear that we need more than one conception of agency, since human and nonhuman animals are capable of thinking and acting in more than one kind of way. In this paper, I make a distinction between perceptual and propositional agency, and I argue that many nonhuman animals are perceptual agents (...) and that many human beings are both kinds of agent. I then argue that, insofar as human and nonhuman animals exercise the same kind of agency, they have the same kind of moral status, and I explore some of the moral implications of this idea.

Can animals act morally? Philosophical tradition answers 'no,' and has apparently convincing arguments on its side. Cognitive ethology supplies a growing body of empirical evidence that suggests these arguments are wrong. This groundbreaking book assimilates both philosophical and ethological frameworks into a unified whole and argues for a qualified 'yes.'.

A groundbreaking argument for the political rights of animals In When Animals Speak, Eva Meijer develops a new, ground-breaking theory of language and politics, arguing that non-human animals speak--and, most importantly, act--politically. From geese and squid to worms and dogs, she highlights the importance of listening to animal voices, introducing ways to help us bridge the divide between the human and non-human world. Drawing on insights from science, philosophy, and politics, Meijer provides fascinating, real-world examples of animal communities who use (...) their voices to speak, and act, in political ways. When Animals Speak encourages us to rethink our relations with other animals, showing that their voices should be taken into account as the starting point for a new interspecies democracy. (shrink)

Christopher Woodard presents a new and rich version of utilitarianism, the idea that ethics is ultimately about what makes people's lives go better. He launches a state-of-the-art defence of the theory, often seen as excessively simple, and shows that it can account for much of the complexity and nuance of everyday ethical thought.

Ng :255–285, 1995. https://doi.org/10.1007/bf00852469) models the evolutionary dynamics underlying the existence of suffering and enjoyment and concludes that there is likely to be more suffering than enjoyment in nature. In this paper, we find an error in Ng’s model that, when fixed, negates the original conclusion. Instead, the model offers only ambiguity as to whether suffering or enjoyment predominates in nature. We illustrate the dynamics around suffering and enjoyment with the most plausible parameters. In our illustration, we find surprising results: (...) the rate of failure to reproduce can improve or worsen average welfare depending on other characteristics of a species. Our illustration suggests that for organisms with more intense conscious experiences, the balance of enjoyment and suffering may lean more toward suffering. We offer some suggestions for empirical study of wild animal welfare. We conclude by noting that recent writings on wild animal welfare should be revised based on this correction to have a somewhat less pessimistic view of nature. (shrink)
