Abstract
In response to Khin Zaw''s pragmatic model of reason, I argue for a normative,Kantian account in which reason actively impels thought andunderstanding towards transcendental ideals. Reason is neither constructedout of what is ready to hand, nor imposes moral laws from a transhistorical content. Reason''s role is to provide the formof our ideas of the good in accordance with which we may shape thecontent in any particular culture. I argue that the well-rehearseddebate between nature and culture cannot be advanced without recourseto metaphysics. Since metaphysics in transcendental, not transcendent,what emerges from metaphysics must be revealed, interrogated andcriticised, never assumed.
