 Scanlon argues that the constructivist account of general normativity is exposed to the objection of bootstrapping, because it tries to justify the normativity of reasons by a method that already assumes the normativity of reason (Scanlon 2014: 96–104). Thus, unlike Korsgaard and Street, Scanlon holds that truths about reasons for action are not true in virtue of being arrived at through some specified procedure of “construction”. We can arrive at conclusions about reasons by engaging in normative reasoning, (for example employing the method of reflective equilibrium.) But the steps in reasoning of this kind involve making substantive judgments about what reasons we have. Because it requires such judgments as inputs, reasoning of this kind is not a process through which all facts about reasons are constructed (Scanlon 2014: 102–103).
