An early objection to Simon Blackburn’s first attempts to breathe new life into expressivism—by solving the Frege-Geach problem—was that whilst viewing compound sentences featuring moral components as expressive of attitudes towards combinations of attitudes might enable one to make out that a thinker who, to take the usual example, asserts the premisses but will not accept the conclusion of a moral modus ponens is at fault because they are involved in a “clash of attitudes”, this does no justice to the (...) data of the problem, since the failing here is logical, not just moral or more generally practical. Blackburn claims to have an effective answer to this objection—a way to see how, as he now puts it, expressivism can after all “deliver the mighty ‘musts’ of logic”. I remain unconvinced. (shrink)
