Is the autonomy of the will a paradoxical idea?

This essay tackles head on the argument that sees an inherent paradox in the autonomy of the will as the ground for the authority of the fundamental practical norms. It points out that only on reductive understandings of the autonomy of the will can this idea be qualified as paradoxical, thereby yielding outcomes that either contradict their premises or present autonomy under a false guise. With that done, it will proceed to offer a conception of the autonomy of the will which is not vulnerable to the paradox, and which may therefore be equipped to rest the fundamental practical norms on solid ground. Throughout this discussion, I will rely on constitutivism about practical reasons to specifically defend the twofold conclusion that (a) the paradox of autonomy can be avoided and that, relatedly, (b) if autonomy is properly conceptualised, it is fully equipped and well positioned to ground the authority of the fundamental practical norms.
