ABSTRACT This article defends the following argument: what makes you and I valuable so that it is wrong to kill us now is what we are (essentially). But we are essentially physical organisms, who, embryology reveals, came to be at conception/fertilisation. I reply to the objection to this argument (as found in Dean Stretton, Judith Thomson, and Jeffrey Reiman), which holds that we came to be at one time, but became valuable as a subject of rights only some time later, (...) in virtue of an acquired characteristic. I argue against this position that the difference between a basic, natural capacity and some degree of development of such a capacity is a mere difference in degree, that this position logically implies the denial of equal personal dignity, and that the selection of the required degree of development of a capacity is necessarily arbitrary.

I am grateful to Dean Zimmerman, Michael Rea, and Derk Pereboom for their close criticism and helpful suggestions for Persons and Bodies. My ideas—especially about the definition of ‘constitution’—have been significantly improved by their comments.

Paul W. Taylor has defended a life-centered ethics that considers the inherent worth of all living things to be the same. l examine reasons for ascribing inherent worth to all living beings, but argue that there can be various levels of inherent worth. Differences in capacities among types of life are used to justify such levels. I argue that once levels of inherent worth are distinguished, it becomes reasonable torestrict rights to human beings.

ABSTRACT In ‘The Pro‐Life Argument from Substantial Identity: A Defence’, Patrick Lee argues that the right to life is an essential property of those that possess it. On his view, the right arises from one's ‘basic’ or ‘natural’ capacity for higher mental functions: since human organisms have this capacity essentially, they have a right to life essentially. Lee criticises an alternative view, on which the right to life arises from one's ‘developed’ capacity for higher mental functions (or development of some (...) other accidental property). I argue that his criticisms of this alternative view are misguided or self‐defeating, and that there are good reasons to hold we have a right to life accidentally rather than essentially. (shrink)

ABSTRACT In this article, I reply to criticisms of Dean Stretton of the pro‐life argument from substantial identity. When the criterion for the right to life proposed by most proponents of the pro‐life position is rightly understood – being a person, a distinct substance of a rational nature – this position does not lead to the difficulties Stretton claims it does.
