In this article I assess the prospects for a particular kind of resolution to Moore’s Paradox. It is that Moore’s Paradox is explained by the existence of a constitutive norm on belief. I focus on a constitutive norm relates that relates belief to knowledge. I develop this explanation. I then present a challenge to it. Norm-based explanations of Moore’s Paradox must appeal to a ‘linking principle’ that explains what is wrong with violating the constitutive norm. But it is difficult to (...) articulate a plausible candidate linking-principle. I show this by canvassing the obvious candidates and articulating the problems with each. (shrink)
