Psychological accounts of personal identity claim that the human person is not identical to the human animal. Advocates of such accounts maintain that the definition and criterion of death for a human person should differ from the definition and criterion of death for a human animal. My contention is instead that psychological accounts of personal identity should have human persons dying deaths that are defined biologically, just like the deaths of human animals. Moreover, if brain death is the correct criterion (...) for the death of a human animal, then it is also the correct criterion for the death of a human person. What the nonidentity of persons and animals requires is only that they have distinct criteria for ceasing to exist. (shrink)

According to a prominent view of organism persistence, organisms cease to exist at death. According to a rival view, organisms can continue to exist as dead organisms. Most of the arguments in favor of the latter view rely on linguistic and common sense intuitions. I propose a new argument for somaticism by appealing to two other sources that have thus far not figured in the debate: the concept of naturalness, and biological descriptions of organisms, in particular in ethology and ecology. (...) I show that if we hone in on the relevant notion of naturalness, we can show that organisms can continue to instantiate the natural property being an organism after death. (shrink)

Most people think it is wrong to take organs from the dead if the potential donors had previously expressed a wish not to donate. Yet people respond differently to a thought experiment that seems analogous in terms of moral relevance to taking organs without consent. We argue that our reaction to the thought experiment is most representative of our deepest moral convictions. We realize not everyone will be convinced by the conclusions we draw from our thought experiment. Therefore, we point (...) out that the state ignores consent in performing mandatory autopsies in some cases. If readers are willing to give up the permissibility of mandatory autopsies, we then offer some metaphysical arguments against posthumous harm. Drawing upon claims about bodies ceasing to exist at death and Epicurean-inspired arguments against posthumous interests, we make a case for an organ conscription policy which respects fundamental liberal principles of autonomy, bodily integrity, and property.

I argue that a corpse cannot be identified with an earlier living body, because it acquires and retains parts in different ways. Contrary to what Joseph LaPorte maintains, there can be neither one principle of part-assimilation nor a non-disjunctive account of persistence conditions that can establish the identity of a living body and a later corpse.

Conceptual change can occur for a variety of reasons; some more scientifically significant than others. The 2006 definition of ‘planet’, which saw Pluto reclassified as a dwarf planet, is an example toward the more mundane end of the scale. I argue however that this case serves as a useful example of a related phenomenon, whereby what appears to be a single kind term conceals two or more distinct concepts with independent scientific utility. I examine the historical background to this case, (...) as a template for developing additional evidence for pluralist approaches to conceptual disputes within science and elsewhere. (shrink)

There remains a need to properly analyze the metaphysical assumptions underlying two organ procurement policies: presumed consent and organ sales. Our contention is that if one correctly understands the metaphysics of both the human body and material property, then it will turn out that while organ sales are illiberal, presumed consent is not. What we mean by illiberal includes violating rights of bodily integrity, property, or autonomy, as well as arguing for or against a policy in a manner that runs (...) afoul of Rawlsian public reason.
