 The problem, at least from the standpoint of the commonsense view, of 5.1’s underinclusion of infants can be avoided while still retaining a shared source of FMS. The accounts can be modified as follows: sophisticated cognitive capacities or the capacity to develop these sophisticated capacities (without losing one’s identity) are necessary and sufficient for FMS. This is usually labeled the “potential” account in the literature (e.g., Stone 1987), although some authors do not use this terminology, but rather speak, for example, of the wrongness of killing due to the loss of a “future like ours” (Marquis 1989 and 1995). One can also treat potentiality as a ground for some, but not full, moral status (Harman 1999, notwithstanding the revisions in Harman 2003) or as only an enhancer of moral status (Steinbock 1992, p. 68). Views differ in their interpretation of potentiality. For example, some deny that a fetus that will die while still a fetus (of any cause) has the relevant potential (Harman 1999, p. 311).
