It's Only Natural! Moral Progress Through Denaturalization

Several philosophers have proposed that key instances of moral progress in the past, as well as perhaps some present or future progressive changes, rely on people overcoming the notion that their current institutions and social practices are “natural, necessary, and inevitable feature[s] of the social world” (Pleasants, “Moral Argument is Not Enough,” 166). I call this account of how moral progress happens denaturalization. In this paper, I provide a more rigorous account of denaturalization than has thus far been provided in the literature, so that its plausibility and its promise as a mechanism of progressive change can be better assessed. I develop an account according to which denaturalization occurs when people come to have more accurate judgments about the costs of abandoning status quo institutions in favor of alternative institutions. I draw on the philosophy of conventionality to develop an account of costs and provide a limited defense of the psychological realism of the costs account of denaturalization. With this more detailed and explicit account in hand, I explore under what kinds of conditions denaturalization is likely to lead to moral progress.
