In “Abortion and Ownership” John Martin Fischer argues that in Judith Jarvis Thomson’s violinist case you have a moral obligation not to unplug yourself from the violinist. Fischer comes to this conclusion by comparing the case with Joel Feinberg’s cabin case, in which he contends a stranger is justified in using your cabin to stay alive. I argue that the relevant difference between these cases is that while the stranger’s right to life trumps your right to property in the cabin (...) case, the violinist’s right to life does not trump your right to liberty in the violinist case.

This paper takes a novel approach to the active bioethical debate over whether advance medical directives have moral authority in dementia cases. Many have assumed that advance directives would lack moral authority if dementia truly produced a complete discontinuity in personal identity, such that the predementia individual is a separate individual from the postdementia individual. I argue that even if dementia were to undermine personal identity, the continuity of the body and the predementia individual’s rights over that body can support (...) the moral authority of advance directives. I propose that the predementia individual retains posthumous rights over her body that she acquired through historical embodiment in that body, and further argue that claims grounded in historical embodiment can sometimes override or exclude moral claims grounded in current embodiment. I close by considering how advance directives grounded in historical embodiment might be employed in practice and what they would and would not justify. (shrink)

Perfectionism is an ambitious and thoroughly engaging work in which Thomas Hurka sets out to formulate and defend a normative ethical theory that “is of sufficient depth and generality to be … the basis of all moral claims”. Beginning with an axiology, Hurka proposes that the development of the properties constitutive of human nature is intrinsically good, and his fundamental moral principle enjoins us to promote the greatest development of the nature of all humans at all times.

I explore two thought-experiments in Judith Jarvis Thomson’s important article, “A Defense of Abortion”: the violinist example and the people-seeds example. I argue (contra Thomson) that you have a moral duty not to unplug yourself from the violinist and also a moral duty not to destroy a people-seed that has landed in your sofa. Nevertheless, I also argue that there are crucial differences between the thought-experiments and the contexts of pregnancy due to rape or to contraceptive failure. In virtue of (...) these differences, it would not follow from my conclusions about the violinist and people-seeds cases that abortion would not be permissible in a case of rape or in a case of voluntary intercourse with contraceptive failure.
