In 1987, Supreme Court Justice Thurgood Marshall delivered a lecture, "The Constitution: A Living Document," in which he argued that the Constitution must be interpreted in light of the moral, political, and cultural climate of the age of interpretation. If JBork's formulation of "the living Constitution" is guiding, any constitutional interpretation other than originalism of one form or another implies the Living Constitution. If, however, Marshall's formulation is guiding, it is unclear whether methods derived from law and economics or the Moral Constitution might be implicated.
