Constitutivism About Practical Principles: Its Claims,Goals, Task and Failure

The aim of this paper is twofold: In its first part, we work out the key features of constitutivism as presented by Christine Korsgaard. This reconstruction serves to clarify which goals Korsgaard wants to achieve with her account and which of its central claims she has to defend in particular. In the second part, we discuss whether Korsgaard can vindicate constitutivism's most central claim. To do this, we analyse two important arguments - the argument from unavoidability and the argument from the abstract constitutive principle - that have been made in support of constitutivism. We show how both these arguments go amiss and conclude that at least for now, constitutivism's most central claim has not been successfully argued for.
