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)

Though many ethicists have the intuition that we should leave nature alone, Kyle Johannsen argues that we have a duty to research safe ways of providing large-scale assistance to wild animals. Using concepts from moral and political philosophy to analyze the issue of wild animal suffering (WAS), Johannsen explores how a collective, institutional obligation to assist wild animals should be understood. He claims that with enough research, genetic editing may one day give us the power to safely intervene (...) without perpetually interfering with wild animals’ liberties.---------------Questions addressed include: In what way is nature valuable and is interference compatible with that value? Is interference a requirement of justice? What are the implications of WAS for animal rights advocacy? What types of intervention are promising?---------------Expertly moving the debate about human relations with wild animals beyond its traditional confines, Wild Animal Ethics is essential reading for students and scholars of political philosophy and political theory studying animal ethics, environmental ethics, and environmental philosophy.

The name ‘pluralism’ frequently rears its head in political philosophy, but theorists often have different things in mind when using the term. Whereas ‘reasonable pluralism’ refers to the fact of moral diversity among citizens of a liberal democracy, ‘value pluralism’ is a metaethical view about the structure of moral practical reasoning. In this paper, I argue that value pluralism is part of the best explanation for reasonable pluralism. However, I also argue that embracing this explanation is compatible with political liberalism’s (...) commitment to avoiding controversial premises. According value pluralism an explanatory role does not entail according it a justificatory one. What’s more, explaining reasonable disagreement in terms of reasonable disagreement about value weights opens up space for direct appeal to substantive values within political liberalism. In particular, promoting a substantive political value when doing so does not conflict with other values is unproblematic. (shrink)

This paper is a summary of my book 'Wild Animal Ethics'.

The systems Kα of transfinite cumulative types up to α are extended to systems K∞α that include a natural infinitary inference rule, the so-called limit rule. For countable α a semantic completeness theorem for K∞α is proved by the method of reduction trees, and it is shown that every model of K∞α is equivalent to a cumulative hierarchy of sets. This is used to show that several axiomatic first-order set theories can be interpreted in K∞α, for suitable α.

We define a property of substructures of models of arithmetic, that of being length-initial, and show that sharply bounded formulae are absolute between a model and its length-initial submodels. We use this to prove independence results for some weak fragments of bounded arithmetic by constructing appropriate models as length-initial submodels of some given model.

We prove some independence results for the bounded arithmetic theoryR 2 0 , and we define a class of functions that is shown to be an upper bound for the class of functions definable by a certain restricted class of ∑ 1 b in extensions ofR 2 0.

In light of the extent of wild animal suffering, some philosophers have adopted the view that we should cautiously assist wild animals on a large scale. Recently, their view has come under criticism. According to one objection, even cautious intervention is unjustified because fallibility is allegedly intractable. By contrast, a second objection states that we should abandon caution and intentionally destroy habitat in order to prevent wild animals from reproducing. In my paper, I argue that intentional habitat destruction is wrong (...) because negative duties are more stringent than positive duties. However, I also argue that the possible benefits of ecological damage, combined with the excusability of unintended, unforeseeable harm, suggest that fallibility should not paralyse us. (shrink)

The purpose of this note is to show that the independence results for sharply bounded arithmetic of Takeuti [4] and Tada and Tatsuta [3] can be obtained and, in case of the latter, improved by the model-theoretic method developed by the author in [2].

G. A. Cohen is well known within contemporary political philosophy for claiming that the scope of principles of justice extends beyond the design of institutions to citizens’ personal choices. More recently, he’s also received attention for claiming that principles of justice are normatively ultimate, i.e., that they’re necessary for the justification of action guiding principles (regulatory rules) but are unsuitable to guide political practice themselves. The purpose of this paper is to explore the relationship between these claims as they’re applied (...) in criticism of John Rawls. It argues that ascribing normative ultimacy to justice entails its application to personal choice. However, it also argues that if Cohen is right about Rawls’s difference principle being regulatory rather than ultimate, then his earlier claim that Rawls must extend it to personal choice on pain of inconsistency is refuted.

G. A. Cohen’s claim that fundamental principles are ‘fact-insensitive’ has not received an especially warm welcome from the philosophical community. While some philosophers have expressed doubts about the plausibility of his claim, others have complained that even if his thesis is true, it is also relatively insignificant. In my paper, I argue that the fact-insensitivity thesis, if true, provides considerable support for value pluralism, and is thus of interest for that reason. Though Cohen himself assumes a plurality of fundamental principles, (...) he never argues that the fact-insensitivity thesis supports this assumption. One of my paper’s aims, then, is to fill an argumentative gap in Cohen’s meta-ethical framework. (shrink)

Conceptual analysis has fallen out of favor in political philosophy. The influence of figures like John Rawls and Ronald Dworkin has led political philosophy to focus on questions about what should be done, and to ignore questions about the usage of words. As a result, contemporary political philosophy lacks a shared understanding of the concept of justice, and a considerable amount of disagreement between political philosophers is, upon reflection, traceable to this. In my book, I call for renewed attention to (...) the manner in which the word ‘justice’ is and should be used. Focusing on the late work of G.A. Cohen, I argue that two major debates in contemporary political philosophy: the debate over luck-egalitarianism and the debate over whether justice imposes demands on citizens’ personal lives; are really just conceptual. Whereas some philosophers have been using the term ‘justice’ to refer to one among a plurality of values, others have been using it to refer to institutional rightness. Though the latter use of ‘justice’ is presently more dominant, I argue that much is to be gained from thinking of justice as one value among many. Doing so sheds light on the nature of both democracy and legitimacy, and, paradoxically, makes better sense of the idea that justice is ‘the first virtue of institutions’. (shrink)

In recent work, economist Yew-Kwang Ng suggests strategies for improving animal welfare within the confines of institutions such as the meat industry. Although I argue that Ng is wrong not to advocate abolition, I do find his position concerning wild animals to be compelling. Anyone who takes the interests of animals seriously should also accept a cautious commitment to intervention in the wild.

The theories Si1 and Ti1 are the analogues of Buss' relativized bounded arithmetic theories in the language where every term is bounded by a polynomial, and thus all definable functions grow linearly in length. For every i, a Σbi+1-formula TOPi, which expresses a form of the total ordering principle, is exhibited that is provable in Si+11 , but unprovable in Ti1. This is in contrast with the classical situation, where Si+12 is conservative over Ti2 w. r. t. Σbi+1-sentences. The independence (...) results are proved by translations into propositional logic, and using lower bounds for corresponding propositional proof systems. (shrink)

G.A. Cohen is famous for his critique of John Rawls’s view that principles of justice are restricted in scope to institutional structures. In recent work, however, Cohen has suggested that Rawlsians get more than just the scope of justice wrong: they get the concept wrong too. He claims that justice is a fundamental value, i.e. a moral input in our deliberations about the content of action-guiding regulatory principles, rather than the output. I argue here that Cohen’s arguments for extending the (...) scope of justice equivocate across his distinction between fundamental principles of justice, i.e. principles that tell us what justice is; and regulatory principles of justice, i.e. principles that tell us what is required of us, all things – including justice – considered. Though Cohen initially had the regulatory sense of the word ‘justice’ in mind when critiquing the basic structure restriction, his replies to the problem of demandingness presuppose his own, fundamental sense of the word ‘justice’. The upshot is that he escapes demandingness at the cost of sacrificing regulatory justice’s capacity to provide clear guidance. I conclude by considering Peter Singer’s efforts to deal with demandingness in his own work on global poverty. Since Singer manages to deal with demandingness without giving up clarity, his work is a good a place to start in the search for regulatory principles that are suitable for the context of personal choice.

In recent work, Andrew T. Forcehimes and Robert B. Talisse correctly note that G.A. Cohen’s fact-insensitivity thesis, properly understood, is explanatory. This observation raises an important concern. If fact-insensitive principles are explanatory, then what role can they play in normative deliberations? The purpose of my paper is, in part, to address this question. Following David Miller, I indicate that on a charitable understanding of Cohen’s thesis, an explanatory principle explains a justificatory fact by completing an otherwise logically incomplete inference. As (...) a result, the explanatory role such a principle plays is inseparable from its status as a (not necessarily successful) justificatory reason. With this interpretation in hand, I then proceed to argue that Lea Ypi’s and Robert Jubb’s recent criticisms fail to undermine Cohen’s thesis, and that fact-insensitive principles, once discovered, are especially helpful for purposes of deliberation in circumstances characterized by changing and changeable feasibility constraints.

The purpose of this paper is to respond to the thoughtful commentaries contained in the 'Wild Animal Ethics' book symposium.

I argue that most wild animals live bad lives, and that we should intervene in nature to improve their wellbeing.

Animal rights philosophers have traditionally accepted the claim that human beings are unique, but rejected the claim that our uniqueness justifies denying animals moral rights. Humans were thought to be unique specifically because we possess moral agency. In this commentary, I explore the claim that some nonhuman animals are also moral agents, and I take note of its counter-intuitive implications.

In contemporary debates about justice, political philosophers take themselves to be engaged with a subject that’s narrower than the whole of morality. Many contemporary liberals, notably John Rawls, understand this narrowness in terms of context specificity. On their view, justice is the part of morality that applies to the context of a society’s institutions, but only has indirect application to the context of citizens’ personal lives. In contrast, many value pluralists, notably G.A. Cohen, understand justice’s narrowness in terms of singularity (...) against a plural background. On their view, justice is one fundamental value amongst a plurality of fundamental values. The purpose of my thesis is to establish that the pluralist conception of justice’s narrowness is theoretically significant and true. To establish its theoretical significance, I argue that proper attention to the ways in which different understandings of narrowness inform the work of contemporary egalitarians explains a considerable amount of disagreement between them concerning the content and scope of distributive justice. On the one hand, I’ll argue that if we understand justice’s narrowness in the manner Cohen and other pluralists do, i.e., understand a conception of justice to be a conception of a particular fundamental value, then both luck-egalitarianism and the claim that justice extends to the personal context are compelling. On the other hand, I’ll argue that if we understand justice’s narrowness in a contextual manner, i.e., understand justice to comprise one or more all-things-considered principles adopted for the institutional context, then both luck-egalitarianism and the claim that justice extends to the personal context prove implausible. To establish the truth of the pluralist conception of narrowness, I argue first, that the contextual understanding is only plausible if fairness should be understood procedurally instead of substantively; and second, that substantive fairness cannot be eliminated, as specifying the content of procedural fairness requires a substantive criterion. The upshot is that justice’s narrowness is best understood in terms of singularity against a plural background, rather than in terms of context specificity. (shrink)

A "slippery slope argument" is a type of argument in which a first step is taken and a series of inextricable consequences follow, ultimately leading to a disastrous outcome. Many textbooks on informal logic and critical thinking treat the slippery slope argument as a fallacy. Walton argues that used correctly in some cases, they can be a reasonable type of argument to shift a burden of proof in a critical discussion, while in other cases they are used incorrectly. Walton identifies (...) and analyzes four types of slippery slope argument. Walton presents guidelines that show how each type of slippery slope argument can be used correctly or incorrectly, using over fifty case studies of argumentation on controversial issues. These include abortion, medical research on human embryos, euthanasia, the decriminalization of marijuana, pornography, and censorship, and banning of American flag burning. (shrink)

The phenomenon "religion" has been studied critically by many disciplines. Philosophy, natural and social sciences, literature, and linguistics have joined the confessional traditions of Catholic and Protestant theology to offer critiques of religious belief and experience. This volume approaches the subject from diverse disciplinary perspectives. It explores their distinctive approaches, methodologies and areas of interest. It also makes a case for interdisciplinarity as a path to new insights.
