The moral ought in conjectural history

Abstract

ABSTRACT This article defends the importance of the idea of historical progress for constructivist justifications of moral normativity inspired by Kant’s analysis of practical reason. Focusing on some key methodological requirements that must be satisfied for the constructivist vindication of practical normativity to succeed, the article focuses on the concept of purposiveness as it develops within Kant’s moral and political philosophy. It concludes that without a critical notion of ‘purposiveness’ and related philosophical analysis of history, the constructivist rejection of scepticism is at risk of circularity.
