Frege-Geach Problem

The Frege-Geach problem is a central issue in metaethics, challenging expressivist theories to justify logical inferences involving moral expressions. Expressivists argue that moral statements express attitudes rather than truth-apt propositions, yet this position struggles with preserving logical coherence in contexts where moral claims are unasserted. Solutions to this problem include Simon Blackburn’s approach involving higher-order attitudes, Mark Schroeder’s ”being for” framework, and Allan Gibbard’s theory of factual-normative worlds. Each framework contributes insights, yet a comprehensive resolution may necessitate combining linguistic and pragmatic analyses with metaethical perspectives to clarify inference patterns in expressivist reasoning.
