Contents

Hadley is known for his account of animal property rights theory. He proposes that wild animals be offered property rights over their territories, and that guardians be appointed to represent their interests in decision-making procedures. He suggests that this account could be justified directly, on the basis of the interests of the animals concerned, or indirectly, so that natural environments are protected. The theory has received discussion in popular and academic contexts, with critical responses from farming groups and mixed responses from moral and political theorists.

Other work has included a defence of a neopragmatist approach to animal ethics, along with criticism of the metaethical and metaphilosophical assumptions of mainstream animal ethicists. Hadley has also conducted research on normative issues related to animal rights extremism, the aiding of others, and utilitarianism.

Career

Hadley read for a Bachelor of Arts and doctorate in philosophy at the University of Sydney (USYD). [1] His doctoral thesis was supervised by Caroline West, [2] in USYD's Department of Philosophy, and was submitted in 2006 under the title of Animal Property: Reconciling Ecological Communitarianism and Species-egalitarian Liberalism. [3] During his doctoral research, the "basic elements" of his animal property rights theory were "first assembled", [2] leading to the publication of "Nonhuman Animal Property: Reconciling Environmentalism and Animal Rights" in the Journal of Social Philosophy . [4] During this time, he also published in the Journal of Value Inquiry , [5] Philosophy in the Contemporary World , [6] and the Journal of Applied Philosophy , [7] as well as working as a lecturer in the USYD philosophy department and a guest lecturer for the USYD Laboratory Animal Services. [1]

After his PhD, Hadley worked as a lecturer in communication ethics in the Charles Sturt University (CSU) School of Communication and a lecturer in philosophy at the CSU School of Humanities and Social Sciences. [8] He then joined the University of Western Sydney School of Humanities and Communication Arts, first as a lecturer in philosophy, [8] and then as a senior lecturer in philosophy. [1] Animal Ethics and Philosophy: Questioning the Orthodoxy, a collection edited by Hadley with the Finnish philosopher Elisa Aaltola, was published in 2015 by Rowman & Littlefield International. The book aimed to move debate in animal ethics beyond developing extensionist accounts and to examine the metaphilosophical and metaethical problems with extensionist accounts. [9] Hadley's own contribution drew attention to a perceived inconsistent triad in animal rights philosophy: the idea that moral status is determined by psychological factors (like sentience), and not species; that human and nonhuman animals are of the same kind; and that genomic plasticity offers the best explanation for change in natural selection. [10] In the same year, Hadley published a monograph with Lexington Books entitled Animal Property Rights: A Theory of Territory Rights for Wild Animals. The book, partially building upon his doctoral research, presents a large amount of new material on Hadley's animal property rights theory. [2] A second monograph, Animal Neopragmatism, was published in 2019 by Palgrave Macmillan. This presented a neopragmatist approach to animal ethics. [11]

A coyote scent-marking. Hadley proposes that the territorial behaviour of sentient animals should be used to determine the extent of the space over which they have a property right.

Hadley is known for his theory of animal property rights, according to which animals should be afforded property rights over their territory. [12] [13] [14] [15] [16] Hadley has developed his theory of animal property rights through his doctoral research, [17] his 2015 monograph, [18] and other academic works. [4] [19] In addition, he has authored popular articles on the subject for The Guardian , [20] The Conversation [21] and The Ethics Centre. [22] He also discussed the topic on Knowing Animals, a podcast series produced by Siobhan O'Sullivan. [23] His proposal has received attention in the popular press, with strong criticism from farmers' groups and journalists writing on rural affairs. [24]

The practical side of Hadley's proposal rests on two key principles: a guardianship system, according to which knowledgeable guardians would be appointed to represent animal property holders in land management decision-making, and the use of animals' territory-marking behaviour to determine the limits of their property. [25] Hadley rejects first occupancy and labour-mixing accounts of appropriation, [26] and instead suggests that there are two ways that his account might fruitfully be justified. [19] First, it might be justified directly, with reference to the interests of animals. This relies upon the fact that wild animals require their territory in order to satisfy their basic needs and the claim that this results in an interest in territory strong enough to ground a right. If animals have a right to use their territory, Hadley claims, then they necessarily have a property right in that territory. [4] [19] [27] Second, it might be justified indirectly, as animals (of some species, at least) might be given property rights as a means of protecting natural environments. [19] [28] Hadley presents his proposal against the backdrop of an explicit pragmatism, [29] and holds that animal property rights theory has the potential to reconcile animal and environmental ethics. [4] [28]

Hadley's proposal has been placed in the context of the "political turn" in animal ethics; the emergence of animal ethics literature focused on justice. [14] [15] Another academic who has proposed that wild animals be afforded property rights over their habitats is the British philosopher Steve Cooke. Like Hadley, he utilises an interest-based account of animal rights, but, unlike Hadley, he suggests that sovereignty would be an appropriate tool to protect animals' interest in their habitat if property fails. [13] [19] Other theorists exploring the normative aspects of human relationships with wild animals explicitly deny that they are extending property rights to animals. The US-based ethicist Clare Palmer, for instance, argues for a duty to respect wild animals' space, but claims that arguing for a property right for these animals would be "difficult", and instead bases her account on the fact that human actions can make animals "painful, miserable and vulnerable". [30]

The Canadian theorists Sue Donaldson and Will Kymlicka are critical of Hadley's proposal to extend property rights to animals, claiming that property rights are insufficient to protect animals' interests. [31] Instead, they argue that animals should be considered sovereign over their territories. [32] They write that

It is one thing to say that a bird has a property right in its nest, or that a wolf has a property right in its den – specific bits of territory used exclusively by one animal family. But the habitat that animals need to survive extends far beyond such specific and exclusive bits of territory – animals often need to fly or roam over vast territories shared by many other animals. Protecting a bird's nest is of little help if the nearby watering holes are polluted, or if tall buildings block its flight path. It's not clear how ideas of property rights can help here. [31]

They also compare the possibility of extending property rights to animals to the approach of European colonists, who were prepared to extend property, but not sovereignty, rights to native peoples, resulting in oppression. [33] Hadley, however, is himself critical of Donaldson and Kymlicka's sovereignty proposal, [34] though the British philosopher Josh Milburn suggests that the proposals may not be as far apart as the authors indicate. [16]

The British political theorist Alasdair Cochrane also questions the extension of property rights to animals in his Animal Rights Without Liberation . Though describing Hadley's proposal as "ingenious", [35] he criticises it on two grounds. First, he questions Hadley's claim of a relationship between property and basic needs, and, second, denies that animal property rights would appease environmentalists, given that they would allow the destruction of environments which do not contain sentient animals. [36] However, in his Sentientist Politics , Cochrane includes animal property rights as part of his critique of Donaldson and Kymlicka's sovereignty model, writing that it "seems perfectly possible to argue, as John Hadley and others have, that wild animals ought to be granted habitat or property rights over their territories". [37] In a book review, Milburn stresses the significance of Hadley's theory, but questions the extent to which the implementation of animal property rights would be desirable without the achievement of other animal rights and the extent to which Hadley's account is genuinely about property rights. [15]

Animal neopragmatism

Having published a number of papers critical of the metaethical and metaphilosophical stances of mainstream animal ethicists in the 2010s, [10] [38] [39] [40] in 2019, Hadley published Animal Neopragmatism. [11] In the book, Hadley sets out a neopragmatist approach to animal ethics. This theory responds to both the "political problem of welfare" and the "philosophical problem of welfare". The former is a perceived difficulty with the democratic legitimacy of animal welfare law, given that folk understanding of welfare stretches beyond the measurable suffering with which a policy approach is concerned. The latter is that, given metatheoretical assumptions of contemporary animal ethicists (especially moral realism), any attempt to extend discussion of welfare beyond feelings is met with the accusation that the subject is being changed: [41] hence Hadley's earlier exploration of the "changing the subject problem". [40] In response to these problems, Hadley outlines his vision of "relational hedonism", according to which a concern for the pain of animals underlies a broader concern that extends beyond a narrow sense of animal welfare, and endorses both experiential pluralism (welfare can be affected by things other than pleasure and pain) and expressivism. [42] The theory of "animal neopragmatism", Hadley argues, is able to overcome metalevel problems in mainstream animal rights theory. [43] [10]

Other research

Hadley has considered the ethics of humans' relationships with wild animals and environments beyond his property rights theory. He argues that there is a duty to aid wild animals in need, and that these duties are essentially no different to humans' duties to aid distant strangers who are severely cognitively impaired. [7] He argues that libertarian property rights, consistent with Robert Nozick's interpretation of the Lockean proviso, should limit the right to destroy human-owned natural environments, [44] and has elsewhere explored libertarian theory's denial of moral powers (including the power to acquire property) to animals. [45]

Hadley has conducted research on animal rights extremism, concluding that the phenomenon is a complex one, and that a full understanding of individual extremists' intentions and targets are necessary to understand the ethical acceptability of extremist acts and whether such acts are appropriately classified as terrorism. [46] He holds that while direct action should be tolerated in liberal democracies, this toleration should not extend to certain campaigning tactics used by extremists, such as threat-making. [47]

With O'Sullivan, Hadley has conducted research on utilitarianism and the relationship between obligations to animals and obligations to needy humans. The scholars argue that there is a conflict in Singer's philosophy between the obligation to aid needy humans and to protect animals, [48] and that Westerners who own pets should, rather than spending large amounts of money extending the lives of their companions, euthanise severely ill animals and instead donate money to aiding those in the developing world. [49]

Hadley has been critical of the views of Tibor Machan [5] and J. Baird Callicott. [50] He has also written on J. M. Coetzee, [51] the ethics of "disenhancing" animals, [52] the ethics of animal testing, [53] the relationship of self-defence theory to abortion and animal ethics, [39] and the ethics of street photography.

<span class="mw-page-title-main">Animal rights</span> Belief that animals have interests that should be considered

Animal rights is the philosophy according to which many or all sentient animals have moral worth independent of their utility to humans, and that their most basic interests—such as avoiding suffering—should be afforded the same consideration as similar interests of human beings. Broadly speaking, and particularly in popular discourse, the term "animal rights" is often used synonymously with "animal protection" or "animal liberation". More narrowly, "animal rights" refers to the idea that many animals have fundamental rights to be treated with respect as individuals—rights to life, liberty, and freedom from torture that may not be overridden by considerations of aggregate welfare.

Paul W. Taylor was an American philosopher best known for his work in the field of environmental ethics.

Ethical extensionism or moral extensionism is a metaethical or metaphilosophical approach in environmental ethics and animal ethics that extends existing ethical theories and concepts to include entities that are traditionally excluded.

Animal ethics is a branch of ethics which examines human-animal relationships, the moral consideration of animals and how nonhuman animals ought to be treated. The subject matter includes animal rights, animal welfare, animal law, speciesism, animal cognition, wildlife conservation, wild animal suffering, the moral status of nonhuman animals, the concept of nonhuman personhood, human exceptionalism, the history of animal use, and theories of justice. Several different theoretical approaches have been proposed to examine this field, in accordance with the different theories currently defended in moral and political philosophy. There is no theory which is completely accepted due to the differing understandings of what is meant by the term ethics; however, there are theories that are more widely accepted by society such as animal rights and utilitarianism.

Wild animal suffering is the suffering experienced by nonhuman animals living outside of direct human control, due to harms such as disease, injury, parasitism, starvation and malnutrition, dehydration, weather conditions, natural disasters, and killings by other animals, as well as psychological stress. Some estimates indicate that these individual animals make up the vast majority of animals in existence. An extensive amount of natural suffering has been described as an unavoidable consequence of Darwinian evolution and the pervasiveness of reproductive strategies which favor producing large numbers of offspring, with a low amount of parental care and of which only a small number survive to adulthood, the rest dying in painful ways, has led some to argue that suffering dominates happiness in nature.

<i>An Introduction to Animals and Political Theory</i> 2010 textbook by Alasdair Cochrane

An Introduction to Animals and Political Theory is a 2010 textbook by the British political theorist Alasdair Cochrane. It is the first book in the publisher Palgrave Macmillan's Animal Ethics Series, edited by Andrew Linzey and Priscilla Cohn. Cochrane's book examines five schools of political theory—utilitarianism, liberalism, communitarianism, Marxism and feminism—and their respective relationships with questions concerning animal rights and the political status of (non-human) animals. Cochrane concludes that each tradition has something to offer to these issues, but ultimately presents his own account of interest-based animal rights as preferable to any. His account, though drawing from all examined traditions, builds primarily upon liberalism and utilitarianism.

<i>Animal Rights Without Liberation</i> 2012 book by British political theorist Alasdair Cochrane

Animal Rights Without Liberation: Applied Ethics and Human Obligations is a 2012 book by the British political theorist Alasdair Cochrane, in which it is argued that animal rights philosophy can be decoupled from animal liberation philosophy by the adoption of the interest-based rights approach. Cochrane, arguing that there is no reason that (nonhuman) animals should be excluded from justice, adopts Joseph Raz's account of interest rights and extends it to include animals. He argues that sentient animals possess a right not to be made to suffer and a right not to be killed, but not a right to freedom. The book's chapters apply Cochrane's account to a number of interactions between humans and animals; first animal experimentation, then animal agriculture, the genetic engineering of animals, the use of animals in entertainment and sport, the relationship of animals to environmental practices and the use of animals in cultural practices.

The work addresses the emergence of academic animal ethics informed by political philosophy as opposed to moral philosophy. It was the first edited collection to be published on the topic, and the first book-length attempt to explore the breadth and boundaries of the literature. As well as a substantial introduction by the editors, it features ten sole-authored chapters split over three parts, respectively concerning institutional change for animals, the relationship between animal ethics and ecologism, and real-world laws made for the benefit of animals. The book's contributors were Wissenburg, Schlosberg, Manuel Arias-Maldonado, Chad Flanders, Christie Smith, Clemens Driessen, Simon Otjes, Kurtis Boyer, Per-Anders Svärd, and Mihnea Tanasescu. The focus of their individual chapters varies, but recurring features include discussions of human exceptionalism, exploration of ways that animal issues are or could be present in political discourse, and reflections on the relationship between theory and practice in politics.

In the book, Cochrane outlines and defends his political theory of "sentientist cosmopolitan democracy". The approach is sentientist in that it recognises all sentient animals as bearers of rights; cosmopolitan in that it extends cosmopolitan political theory to include animals, rejecting the importance of state borders and endorsing impartiality; and democratic in that it aims to include animals in systems of representative and cosmopolitan democracy. It was the first book to extend cosmopolitan theory to animals, and was a contribution to the "political turn" in animal ethics – animal ethics informed by political philosophy.
