How successful is Allan Gibbard’s attempt to solve the Frege-Geach problem for moral non-cognitivism? This author argues that Gibbard is on the right track with his formalism, but is missing an argument about inconsistency that matches the strength of truth-functional logic. The paper includes discussions of non-cognitivism, the Frege-Geach problem, a summary of Gibbard’s argumentation, and summaries of various strong criticisms of Gibbard’s efforts. The author emphasizes the weakness of relying on practical considerations when it comes to consistency between all possible normative moral judgments, yet supports Schroeder’s insight that might help to improve Gibbard’s reasoning.
