Abstract

This paper advances a novel hybrid theory addressing a fundamental puzzle in legal philosophy: how legal statements can simultaneously have both cognitive and practical features. Drawing on contemporary developments in metaethics and philosophy of language, we argue that legal statements express both beliefs and desire-like attitudes. My analysis yields three key findings. First, I demonstrate that within any given legal system, the descriptive content of legal statements remains invariant across different contexts of use and assessment – a feature that explains persistent patterns of legal disagreement, retraction and attribution of responsibility for content. Second, I show that the desire-like states expressed by legal statements are uniformly directed at the general property picked out by “It is the law that…” rather than at particular legal norms, regardless of the speaker – thereby preserving their inference-licensing property and evidential function. Third, I identify generalized conversational implicature as the mechanism through which legal statements convey desire-like states explaining their distinctive practical features. This theoretical framework offers a novel solution to the puzzle of legal motivation: rather than positing a necessary conceptual link between legal judgment and motivation, it explains their characteristic connection through the general action-guiding purpose of legal discourse and Gricean conversational principles.
