 The rival candidates and thinking parts problems are instances of what we might call “multiplication objections” to animalism. These objections try to demonstrate how advocates of animalism are committed to claiming (or incapable of denying) that one thing (you or me, say) is identical to each of two or more things. Yet another such objection is inspired by a rare type of conjoined twinning called dicephalus, which occurs when a human zygote divides only partially before implanting in the uterine wall. The result is twins conjoined below the neck. These twins look like a two-headed person, with distinct heads and necks sprouting from a single torso (Miller 1996). According to McMahan (2002: 35), because a pair of dicephalic twins is two people but only one animal, dicephalic twins appear to present a walking, talking counterexample to animalism’s hallmark claim, (1).
