Reproductive cloning and arguments from potential

Abstract

The possibility of human reproductive cloning has led some bioethicists to suggest that potentiality-based arguments for fetal moral status become untenable, as such arguments would be committed to making the implausible claim that any adult somatic cell is itself a potential person. In this article I defend potentiality-based arguments for fetal moral status against such a reductio. Starling from the widely-held claim that the maintenance of numerical identity throughout successive changes places constraints on what a given entity can plausibly be said to have the potential to become, I argue that the cell reprogramming that takes place in reproductive cloning is such that it produces a new individual, and so adult somatic cells cannot be potential persons.
