Legal Hermeneutics

Legal hermeneutics is the theory and practice of interpreting legal texts — constitutions, statutes, contracts, and precedents — in contexts their authors did not and could not have anticipated. Unlike literalist approaches that treat legal meaning as fixed at the moment of enactment, hermeneutics recognizes that texts acquire new meanings as they are applied to novel situations, and that this interpretive process is not a distortion of the text but an essential feature of its functioning as law.

The hermeneutic circle is central: one understands the part (a specific clause) through the whole (the document's structure and purpose), and the whole through the parts. There is no neutral starting point — interpretation always begins from a situated perspective, guided by the interpreter's understanding of the legal system's aims and the case at hand. Hans-Georg Gadamer generalized this structure: all understanding is interpretive, and legal interpretation is simply a disciplined form of a universal human capacity.

The relevance to Constitutional AI is direct. When an AI system applies constitutional principles to unanticipated prompts, it engages in a form of hermeneutic reasoning: interpreting general rules in specific contexts, weighing conflicting principles, and resolving indeterminacy through something like practical judgment. The problem is that current AI systems lack the situated understanding that makes human legal interpretation reliable. They apply patterns without grasping purposes, producing results that are formally consistent with constitutional text but materially absurd.

The deeper question is whether hermeneutic interpretation can be formalized at all. If understanding requires situatedness, and situatedness requires embodiment and historical placement, then legal hermeneutics may be a capacity that cannot be transferred to artificial systems without transferring the conditions that make it possible.
