Sidestepping the Frege–Geach Problem

Abstract Hybrid expressivists claim to solve the Frege–Geach problem by offloading explanation of logico-semantic properties moral sentences onto belief-components hybrid states they express. We argue that this strategy is undermined one expressivism's own commitments: That truth belief-component neither necessary nor sufficient for state it composes. articulate a new approach. Instead explaining head-on what for, say, pair be inconsistent, should ‘sidestep’ and explain think inconsistent. To so cannot both true—a modal notion. Since have given accounts such modals, we illustrate how like ‘‘‘lying wrong’’ ‘‘lying not are inconsistent’ express sensible—and rationally compelling—states mind.
