The simple constitutivist move

A common feature of all versions of constitutivism is the “simple constitutivist move” to the effect that engagement in any enterprise requires respecting the constitutive standards of the enterprise on pain of failing to engage in it. The move is both trivial and powerful in addressing skeptical challenges. I argue that this move only helps transmitting the robust authority of standards that are externally grounded, even when applied to functional items or constitutive aims. This is not a problem for modest versions of constitutivism, but more ambitious constitutivists seems to require supplementation to ground robust or authoritative normativity. Unfortunately, the usual appeal to inescapability is at best a defensive move. Ambitious constitutivism needs to look elsewhere in its search for a positive explanation of the source of robust normativity. The simple constitutivist move, even when combined with inescapability, is indeed too simple.
