Constructing a Moorean ‘Open Question’ Argument: The Real Thought Move and the Real Objective

Abstract

Abstract How Moore’s open question argument works, insofar as it does, remains a matter of controversy. The author’s purpose here is to construct an open question argument based on a novel interpretation of how Moore’s argument might work. In order to sidestep exegetical questions, he does not claim to be offering Moore’s own argument. Rather, the author offers a reconstruction, making use of important elements of Moore’s methodology and assumptions that could be reasonable within a Moorean viewpoint. The crucial role within the argument is played by what the author calls the real thought move. He shows that the reconstructed argument is more defensible from some standard objections than the common construction. The author finishes by drawing attention to a neglected objective that would make sense within Moore’s viewpoint, showing that it fits with a major commitment of Bonjour’s moderate rationalism, and showing how the package might be important for the non-naturalist today.
