Abstract
According to constitutivism, the objective authority of practical reason is to be grounded in the constitutive features of agency. In this paper, I offer a brief survey of the basic structure of constitutive argument about objectivity and consider how constitutivism might dispel the worry that it can only ground a conditional kind of authority. I then consider David Enoch’s original shmagency challenge and the response in terms of the inescapability of agency. In particular, I revisit the appeal to inescapability in light of Enoch’s restatement of the challenge in 'Shmagency Revisited'. I argue that the revised challenge still fails but that it helps clarify: first, the distinction between external and internal challenges to constitutivism, and, second, the existence of at least different kinds of inescapability of agency (metaphysical, psychological, and dialectical). I argue that only dialectical inescapability is helpful to show that constitutivism is a viable metanormative theory. I conclude by claiming that an internal challenge to constitutivism is still possible in principle but that the burden of proof has shifted once again to the critics of constitutivism.
