What is the semantic content and evolutionary function of normative judgments such as wisdom, foolishness, and emotional aptness?

He argues that normative judgments are not merely descriptive but serve a specific function in human social coordination, proposing that our capacity for such judgments is an evolved trait that facilitates complex social interaction.

Experts recognize this work as a foundational text in contemporary metaethics, particularly for its influence on expressivist theories of normative language. Readers frequently note the academic density of the prose, which requires a strong background in analytic philosophy to fully grasp the author's arguments.
