The future‐like‐ours argument, animalism, and mereological universalism

AbstractWhich metaphysical theories are involved—whether presupposed or implied—in Marquis’ future‐like‐ours (FLO) argument against abortion? Vogelstein has recently argued that the supporter of the FLO argument faces a problematic dilemma; in particular, Marquis, the main supporter of the argument, seems to have to either (a) abandon diachronic universalism (DU) or (b) acquiesce and declare that contraception is morally wrong. I argue that the premises of Marquis’ argument can be reasonably combined with a form of unrestricted composition and that the FLO argument is better viewed as including animalism, i.e., the thesis that we are animals.
