 It is of considerable interest to those who follow Kant to determine which reading — teleological or deontological — was actually Kant’s, as well as which view ought to have been his. A powerful argument for the teleological reading is the motivation for Herman’s proposal: What rationale can we provide for doing our duty at all if we don’t appeal to it’s being good to do it? But a powerful argument for the deontological reading is Kant’s own apparent insistence that the authority of moral demands must come simply from their being the demands of a rational will, quite apart from the value that will may have (see Schneewind 1996; Johnson 2007, 2008; and Reath 1994). On the latter view, moral demands gain their authority simply because a rational will, insofar as you are rational, must will them. Proponents of this reading are left with the burden of answering Herman’s challenge to provide a rationale for having willed such demands, although one response may be that the very question Herman raises does not make sense because it asks, in effect, why it is rational to be rational. On the former view, by contrast, a rationale is at hand: because your will is, insofar as it is rational, good. Proponents of this former reading are, however, then left with the burden of explaining how it could be the autonomy of the will alone that explains the authority of morality.
