Having encountered landmines in offering a critique of philosophy based on my experience as the mother of a cognitively disabled daughter, I ask, “Should I continue?” I defend the idea that pursuing this project is of a piece with the invisible care labor that is done by people with disabilities and their families. The value of attempting to influence philosophical conceptions of cognitive disability by virtue of this experience is justified by an inextricable relationship between the personal, the political, and (...) the philosophical. If one grants that the “special relationship” between mother and child requires moral recognition, then I need first to make vivid the case that this relationship in the case of a child who lacks some “normal capacities” is indistinguishable from any mother‐child relationship. If this is so, then I believe I can make a case that has as its conclusion that the moral personhood of even the severely cognitively disabled must be granted. Moreover, such recognition, I argue, necessitates the recognition of others who bear no special relationships to the child. (shrink)

In this article I examine the proposition that severe cognitive disability is an impediment to moral personhood. Moral personhood, as I understand it here, is articulated in the work of Jeff McMahan as that which confers a special moral status on a person. I rehearse the metaphysical arguments about the nature of personhood that ground McMahan’s claims regarding the moral status of the “congenitally severely mentally retarded” (CSMR for short). These claims, I argue, rest on the view that only intrinsic (...) psychological capacities are relevant to moral personhood: that is, that relational properties are generally not relevant. In addition, McMahan depends on an argument that species membership is irrelevant for moral consideration and a contention that privileging species membership is equivalent to a virulent nationalism (these will be discussed below). In consequence, the CSMR are excluded from moral personhood and their deaths are less significant as their killing is less wrong than that of persons. To throw doubt on McMahan’s conclusions about the moral status and wrongness of killing the CSMR I question the exclusive use of intrinsic properties in the metaphysics of personhood, the dismissal of the moral importance of species membership, and the example of virulent nationalism as an apt analogy. I also have a lot to say about McMahan’s empirical assumptions about the CSMR. (shrink)
