A century ago the pragmatists called for reconstruction in philosophy. Philosophy at the time was occupied with conceptual analysis, abstractions, a priori analysis, and the pursuit of necessary, universal truths. Pragmatists argued that philosophy instead should center on the pressing problems of the day, which requires theorists to pay attention to social complexity, variation, change, power, consequences, and other concrete aspects of social life. The parallels between philosophy then and jurisprudence today are striking, as I show, calling for a pragmatism-informed theory of law within contemporary jurisprudence. In the wake of H.L.A. Hart’s mid-century turn to conceptual analysis, “during the course of the twentieth century, the boundaries of jurisprudential inquiry were progressively narrowed.”1 Jurisprudence today is dominated by legal philosophers engaged in conceptual analysis built on intuitions, seeking to identify essential features and timeless truths about law. In the pursuit of these objectives, they detach law from its social and historical moorings, they ignore variation and change, they drastically reduce law to a singular phenomenon—like a coercive planning system for difficult moral problems2—and they deny that coercive force is a universal feature of law, among other ways in which they depart from the reality of law; a few prominent jurisprudents even proffer arguments that invoke aliens or societies of angels.
