In recent years, there has been tremendous growth of interest in the connectionsbetween law and philosophy, but the diversity of approaches that claim to be workingat the intersection of these disciplines might suggest that this area of inquiry is sofractured as to be incoherent. This volume gathers leading scholars to provide focusedand straightforward articulations of the role that philosophy might play at this junctureof the history of American legal thought.The volume marks the seventy-fifth anniversary of Karl Llewellyn’s essay “On Philosophyin American Law” in which he rehearsed the broad development of Americanjurisprudence, diagnosed its contemporary failings, and then charted a productive pathopened by the variegated scholarship that claimed to initiate a realistic approach tolaw and legal theory. The essays are written in the spirit of Llewellyn’s article: they aresuccinct and direct arguments about the potential for bringing law and philosophytogether.
