Re-constructing Kant: Kant's Teleological Moral Realism

It is common for constructivists to claim that Kant was the first philosopher to understand moral facts as 'constructions of reason'. They think that Kant, just like the constructivist, proposes a procedure - the Categorical Imperative - from which the order of value can be 'constructed' and grounds the validity of this construction procedure not in some previous value but in its capacity to solve a practical problem, the problem of 'free agency'. I here argue that this reading is misguided and propose that we read Kant as a teleological realist instead. Kant is a realist in that he takes the value of rational nature to be objective and so not 'constructed'. Kant is a teleological realist insofar as his derivation of the moral law from the objective value of rational nature relies on a teleological understanding of rational nature.
