In this brief, we argue that there is a diversity of ways in which humans (Homo sapiens) are ‘persons’ and there are no non-arbitrary conceptions of ‘personhood’ that can include all humans and exclude all nonhuman animals. To do so we describe and assess the four most prominent conceptions of ‘personhood’ that can be found in the rulings concerning Kiko and Tommy, with particular focus on the most recent decision, Nonhuman Rights Project, Inc v Lavery.

As global business operations expand, managers need more knowledge of foreign cultures, in particular, information on the ethics of doing business across borders. The purpose of this paper is twofold: to share the Islamic perspective on business ethics, little known in the west, which may stimulate further thinking and debate on the relationships between ethics and business, and to provide some knowledge of Islamic philosophy in order to help managers do business in Muslim cultures. The case of Egypt illustrates some (...) divergence between Islamic philosophy and practice in economic life. The paper concludes with managerial implications and suggestions for further research.

In December 2013, the Nonhuman Rights Project (NhRP) filed a petition for a common law writ of habeas corpus in the New York State Supreme Court on behalf of Tommy, a chimpanzee living alone in a cage in a shed in rural New York (Barlow, 2017). Under animal welfare laws, Tommy’s owners, the Laverys, were doing nothing illegal by keeping him in those conditions. Nonetheless, the NhRP argued that given the cognitive, social, and emotional capacities of chimpanzees, Tommy’s confinement constituted (...) a profound wrong that demanded remedy by the courts. Soon thereafter, the NhRP filed habeas corpus petitions on behalf of Kiko, another chimpanzee housed alone in Niagara Falls, and Hercules and Leo, two chimpanzees held in research facilities at Stony Brook University. Thus began the legal struggle to move these chimpanzees from captivity to a sanctuary, an effort that has led the NhRP to argue in multiple courts before multiple judges. The central point of contention has been whether Tommy, Kiko, Hercules, and Leo have legal rights. To date, no judge has been willing to issue a writ of habeas corpus on their behalf. Such a ruling would mean that these chimpanzees have rights that confinement might violate. Instead, the judges have argued that chimpanzees cannot be bearers of legal rights because they are not, and cannot be persons. In this book we argue that chimpanzees are persons because they are autonomous. (shrink)

This paper proves a precisification of Hume’s Law—the thesis that one cannot get an ought from an is—as an instance of a more general theorem which establishes several other philosophically interesting, though less controversial, barriers to logical consequence.

A critical survey of Quine's arguments against the analytic/synthetic distinction.

When I was eleven, my form teacher, Mr Howard, showed some of my class how to punch. We were waiting for the rest of the class to finish changing after gym, and he took a stance that I would now call shizentai yoi and snapped his right fist forward into a head-level straight punch, pulling his left back to his side at the same time. Then he punched with his left, pulling back on his right. We all lined up in (...) our ties and sensible shoes (this was England) and copied him—left, right, left, right—and afterwards he told us that if we practised in the air with sufficient devotion for three years, then we would be able to use our punches to kill a bull with one blow. I worshipped Mr Howard (though I would sooner have died than told him that) and so, as a skinny, eleven-year-old girl, I came to believe that if I practised, I would be able to kill a bull with one blow by the time I was fourteen. This essay is about epistemic viciousness in the martial arts, and this story is illustrates just that. Though the word ‘viciousness’ normally suggests deliberate cruelty and violence, I will be using it here with the more old-fashioned meaning, possessing of vices. Vices (such as avarice, alcoholism and nail-biting) are common, and most of us struggle with a few, but ‘epistemic’ means ‘having to do with knowledge and the justification of belief’ and so epistemic viciousness is the possession of vices that make one bad at acquiring true beliefs, or give one a tendency to form false ones. My eleven-year-old self possessed the epistemic vice of gullibility and hence showed a streak of epistemic viciousness, which led to the formation of a false belief. Other kinds of epistemic vice can lead to us failing to form true beliefs when we ought to. Consider the internet-surfing karate-sensei who stumbles upon an article claiming that chocolate milk is better than water or sports drinks for promoting recovery after strenuous exercise, and describing an experiment using stationary bikes performed at the University of Indiana, purporting to support this claim..

I should like to offer my greatest thanks to Paul Griffiths for providing the opportunity for this exchange, and to commentators Gillian Brown, Steven Fuller, Stefan Linquist, and Erika Milam for their generous and thought-provoking comments. I shall do my best in this space to respond to some of their concerns.

I was quite excited when I first read Restall and Russell’s (2010) paper. For two reasons. First, because the paper provides rigorous formulations and formal proofs of implication barrier the- ses, namely “theses [which] deny that one can derive sentences of one type from sentences of another”. Second (and primarily), because the paper proves a general theorem, the Barrier Con- struction Theorem, which unifies implication barrier theses concerning four topics: generality, necessity, time, and normativity. After thinking about the paper, I (...) am satisfied with its treatment of the first three topics, namely generality, necessity, and time. But I am not satisfied with its treatment of normativity, so my comments are exclusively on that topic. (shrink)

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

Critical review of Gillian Russell's "Truth in Virtue of Meaning".

How to respond to unauthorized migration and migrants is one of the most difficult questions in relation to migration theory and policy. In this commentary on Gillian Brock’s discussion of “irregular” migration, I do not attempt to give a fully satisfactory account of how to respond to unauthorized migration, but rather, using Brock’s discussion, try to highlight what I see as the most important difficulties in crafting an acceptable account, and raise some problems with the approach that Brock takes. (...) In thinking about unauthorized migration, both while trying to craft positive policies and while critiquing existing practices, we need to ask if we are most interested in a general account of how to respond to unauthorized migration, one that would apply to the large majority of cases and provide us a default approach, or if we are better served by taking a piecemeal approach, looking at why certain people or certain groups should be exempt from removal, even if they would otherwise be liable to it. In this paper, I will focus primarily on this distinction, and argue that it is at least important to provide an account of the "generic unauthorized". (shrink)

Gillian Russell has recently proposed counterexamples to such elementary argument forms as Conjunction Introduction and Identity. These purported counterexamples involve expressions that are sensitive to linguistic context—for example, a sentence which is true when it appears alone but false when embedded in a larger sentence. If they are genuine counterexamples, it looks as though logical nihilism—the view that there are no valid argument forms—might be true. In this paper, I argue that the purported counterexamples are not genuine, on the (...) grounds that they equivocate. Having defused the threat of logical nihilism, I argue that the kind of linguistic context sensitivity at work in Russell’s purported counterexamples, if taken seriously, far from leading to logical nihilism, reveals new, previously undreamt-of valid forms. By way of proof of concept I present a simple logic, Solo-Only Propositional Logic, designed to capture some of them. Along the way, some interesting subtleties about the fallacy of equivocation are revealed. (shrink)

Gillian Brock's "Global Justice: A Cosmopolitan Account" and Darrel Moellendorf's "Global Inequality Matters" present carefully crafted accounts of the obligations we have to non-compatriots and offer practical proposals for how we might get closer to meeting these obligations.

In the course of presenting a compelling and comprehensive framework for immigration justice, Brock (2020) addresses discriminatory immigration policies, focusing on recent attempts by the Trump administration to exclude Muslims from the U.S. (the ‘Muslim ban’). This essay critically assesses Brock’s treatment of the issue, and in particular the question of what made the Muslim ban and similar policies unjust. Through examining these issues, further questions regarding the immigration justice framework on offer arise.

It is regrettably common for theorists to attempt to characterize the Humean dictum that one can’t get an ‘ought’ from an ‘is’ just in broadly logical terms. We here address an important new class of such approaches which appeal to model-theoretic machinery. Our complaint about these recent attempts is that they interfere with substantive debates about the nature of the ethical. This problem, developed in detail for Daniel Singer’s and Gillian Russell and Greg Restall’s accounts of Hume’s dictum, is (...) of a general type arising for the use of model-theoretic structures in cashing out substantive philosophical claims: the question of whether an abstract model-theoretic structure successfully interprets something often involves taking a stand on non-trivial issues surrounding the thing. In the particular case of Hume’s dictum, given reasonable conceptual or metaphysical claims about the ethical, Singer’s and Russell and Restall’s accounts treat obviously ethical claims as descriptive and vice versa. Consequently, their model-theoretic characterizations of Hume’s dictum are not metaethically neutral. This encourages skepticism about whether model-theoretic machinery suffices to provide an illuminating distinction between the ethical and the descriptive. (shrink)

I revisit themes from Against Borders: Why the World Needs Free Movement of People(2020) in dialogue with Gillian Brock’s Justice of People on the Move(2020) and Sarah Song’sImmigration and Democracy (2019). We share the conviction that current border regimes are deeply unjust but differ in what migration justice requires. Brock and Song continue to give states significant discretion to exclude people from entering and settling in their territories, whereas I contend that migration justice demands open borders. I reject the (...) claim that state self-determination justifies migration restrictions. Central arguments for open borders high-light the role that restrictive border controls and the state category of‘immigrant’ play in upholding racialised hierarchies and exploitative economic relations, as well as in inflicting violence against mobile people.

Cosmopolitans like Gillian Brock, Charles Beitz, and Thomas Pogge argue that the principles of justice selected and arranged in lexical priority in Rawls’ first original position would—and should for the same reasons as in the first—also be selected in Rawls’ second original position. After all, the argument goes, what reasons other than morally arbitrary ones do we have for selecting a second set of principles? A different, though undoubtedly related, point of contention is the cosmopolitan charge that Rawls fails (...) to consider the unfavorable conditions that owe themselves to global factors. Perhaps there was a time when interconnectedness and interdependency between states was not a factor, but in the current global order, this is certainly not the case. While this paper will address other related cosmopolitan concerns mentioned in Brock’s work, it is these two points that are perhaps the two biggest threats to the Rawlsian project and, as such, it is these two points that will be the primary focus of this paper.

Feminist philosophers of science have long discussed the importance of taking situatedness into account in scientific practices to avoid erasing important aspects of lived experience. Through the example of Gillian Einstein’s [2012] situated neuroscience, I will add support to Gallagher’s [2019] claims that intertheoretic reduction is problematic and provide reason to think pluralistic methodologies are explanatorily and ethically preferable.

In her debate with Michael Blake, Gillian Brock sets out to justify emigration restrictions on medical workers from poor states on the basis of their free-riding on the public investment that their states have made in them in form of a publicly funded education. For this purpose, Brock aims to isolate the question of emigration restrictions from the larger question of responsibilities for remedying global inequalities. I argue that this approach is misguided because it is blind to decisive factors (...) at play in the problem of medical brain drain and consequently distorts the different responsibilities this problem generates. Brock’s strategy, if successful, would effectively lead to punishing emigrating workers from poor states for the free-riding and exploitation that is committed by affluent states – which is a counter-intuitive result.
