This collection of jurisprudential essays explores the possibility and value of adhering to rules in judicial decisionmaking. Responding to Frederick Schauer's work on rules and legal reasoning, the book expands the debate into postmodernism, practical reason, criminal law jurisprudence, moral philosophy, and law and economics. Schauer and the analytic tradition within which he writes meets Foucault, Wittgenstein, Game Theory, Dworkinians and Jesuits.
