Lockean accounts of personal identity face a problem of too many thinkers arising from their denial that we are identical to our animals and the assumption that our animals can think. Sydney Shoemaker has responded to this problem by arguing that it is a consequence of functionalism that only things with psychological persistence conditions can have mental properties, and thus that animals cannot think. I discuss Shoemaker’s argument and demonstrate two ways in which it fails. Functionalism does not rid the (...) Lockean of the problem of too many thinkers. (shrink)

: A key consideration in favour of animalism—the thesis that persons like you and me are identical to the animals we walk around with—is that it avoids a too many thinkers problem that arises for non-animalist positions. The problem is that it seems that any person-constituting animal would itself be able to think, but if wherever there is a thinking person there is a thinking animal distinct from it then there are at least two thinkers wherever there is a thinking (...) person. Most find this result unacceptable, and some think it provides an excellent reason for accepting animalism. It has been argued, however, that animalists face an analogous problem of too many thinkers, the so-called corpse problem, as they must accept both 1) that we are distinct from our bodies, as our bodies can and we cannot persist through death as corpses and 2) that our bodies can think. I argue that the best reasons animalists have for accepting the two claims that generate the distinctness part of the problem double up as reasons to reject the claim that our bodies can think, and vice versa. I argue further that Lockeans cannot similarly get around their problem of too many thinkers. (shrink)

Many philosophers want to say both that everything is determined by the physical and subject to physical laws and principles, and that certain mental entities cannot be identified with any physical entities. The problem of mental causation is to make these two assumptions compatible with the causal efficacy of the mental. The concern is that this physicalist picture of the world leaves no space for the causal efficacy of anything non-physical. The physical, as it is sometimes said, excludes anything non- (...) physical from doing causal work. (shrink)

I focus on two arguments, due to Jaegwon Kim and Trenton Merricks, that move from claims about the sufficiency of one class of causes to the reduction or elimination of another class of entity, via claims about overdetermination. I argue that in order to validate their move from sufficiency to reduction or elimination, both Kim and Merricks must assume that there can be no ‘weak overdetermination’; i.e., that no single effect can have numerically distinct but dependently sufficient causes occurring at (...) the same time. One problem for both arguments is that weak overdetermination isn't obviously objectionable. That point has been well made before. But I want here to go further than merely shifting the burden of proof onto the advocates of overdetermination arguments. I want to tease out why they are so convinced that we must resist weak overdetermination and explain why their conviction is misguided. Both Merricks and Kim, I shall argue, ultimately rest their case on the same motivating principle, wh.. (shrink)

The legal order of the oceans has seen rapid developments and paradigm shifts. At least one of them has been described as a textbook example of a Grotian Moment: the emergence of the customary international law on the continental shelf, stemming from increased demand for oil and gas, coupled with technological advances and the Truman Proclamation of 1945. Now, eighty years later, the law of the sea is again faced with fundamental changes as the basis for maritime limits is eroded (...) by sea level rise. State practice, going back at least a century, has demonstrated that maritime limits normally fluctuate with physical changes to the coast. This understanding has not caused significant changes to the extent or location of maritime entitlements in a historical context. However, sea level rise stands to have catastrophic impacts as the submergence of individual coastal features can cause the loss of maritime areas spanning hundreds of thousands of square kilometres. This realisation has ignited a movement to change the law on maritime limits. Around 2010, the first States began to declare that their maritime limits would be stable, notwithstanding subsequent sea level rise. Several States and a coalition of States have since made similar declarations and the study of the ila Committee on International Law and Sea Level Rise indicates that the practice is in a phase of crystallisation. That suggests that new customary international law may be developing and the events leading to these developments might justify the use of the term Grotian Moment, leading to accelerated formation of customary international law or revised interpretation of the current law. The traditional requirements of State practice and opinio juris are not satisfied at present. However, the impacts of sea level rise on maritime limits may represent a moment of discovery that unveils a hidden truth about the law, overriding the traditional interpretation that renders maritime limits ambulatory.

Many personal identity theorists claim that persons are distinct from the animals that constitute them, but when combined with the plausible assumption that animals share the thoughts of the persons they constitute, this denial results in an excess of thinkers and a host of related problems. I consider a number of non-animalist solutions to these problems and argue that they fail. I argue further that satisfactory non-animalist solutions are not forthcoming and that in order to avoid these problems we ought (...) to affirm our identity with animals. I then discuss arguments to the effect that i) animalism faces its own problems of too many thinkers, arising from the non- identity of animals with thinking bodies and thinking body parts, and ii) that in order to avoid these problems we must deny not just that there are persons distinct from animals, but that there are bodies and body parts distinct from animals Once the second of these claims is granted, there is a short further step to the conclusion that there are no such things as body parts, and from there there is a direct route to eliminative animalism. Eliminative animalism denies not only that there are persons distinct from animals, but that there are any composite objects distinct from animals. This position has been gaining popularity recently, but I argue that we need not, and indeed should not, accept it. Although the problems of the thinking animal do commit us to animalism, the problems of thinking bodies and thinking body parts do not commit us to eliminate animalism. (shrink)
