Amazon.com description: Product Description: The essays in this volume are all concerned with the arguments about law as a system of rule-based decision-making, particularly the ideas advanced by legal philosopher Frederick Schauer. Schauer's work has not only helped revive interest in legal formalism, but has also helped relocate arguments about he relationship between posited rules and morality. The contributors to this volume, themselves distinguished theorists, have concentrated on three aspects of Schauer's work: the nature of jurisprudential description; his theory of presumptive positivism; and the application of his theory of rule-based decision-making to other areas of legal and moral thought.
