This is the first book-length study in English of Kant's legal metaphors, whose philosophical importance has so far been overlooked. It will appeal to academic researchers and advanced students of Kant, early modern philosophy, legal philosophy, and intellectual history.

How should we act? How should the world be organised? This book offers answers to these questions by analysing Kant's conception of normativity. It presents different applications of Kant's theory of normativity to meta-ethical, moral, juridical and political issues of contemporary relevance.

An important part of the legal domain has to do with rule-governed conduct, and is expressed by the use of notions such as norm, obligation, duty and right. These require us to acknowledge the normative dimension of law. Normativity is, accordingly, to be regarded as a central feature of law lying at the heart of any comprehensive legal-theoretical project. The essays collected in this book are meant to further our understanding of the normativity of law. More specifically, the book stages a thorough discussion of legal normativity as approached from three strands of legal thought that are particularly influential and which play a key role in shaping debates on the normative dimension of law: the theory of planning agency, legal conventionalism and the constitutivist approach. While the essays presented here do not aspire to give an exhaustive picture of these debates - an aspiration that would be, by its very nature, unrealistic - they do provide the reader with some authoritative statements of some widely discussed families of views of legal normativity. In pursuing this objective, these essays also encourage a dialogue between different traditions of study of legal normativity, stimulating those who would not otherwise look outside their tradition of thought to engage with new ideas and, ultimately, to arrive at a more comprehensive account of the normativity of law.

Practical Reason and Norms focuses on three problems: In what way are rules normative, and how do they differ from ordinary reasons? What makes normative systems systematic? What distinguishes legal systems, and in what consists their normativity? All three questions are answered by taking reasons as the basic normative concept, and showing the distinctive role reasons have in every case, thus paving the way to a unified account of normativity. Rules are a structure of reasons to perform the required act and an exclusionary reason not to follow some competing reasons. Exclusionary reasons are explained, and used to unlock the secrets of orders, promises, and decisions as well as rules. Games are used to exemplify normative systems. Inevitably, the analysis extends to some aspects of normative discourse, which is truth-apt, but with a diminished assertoric force.

A milestone in Kant scholarship, this interpretation of his critical philosophy makes sense of his notorious 'synthetic judgments a priori'.

The first accessible, detailed overview of the debates about normative reasons, developing a new theory based on why-questions.

What are our duties or rights? How should we act? What are we responsible for? Joseph Raz examines the philosophical issues underlying these everyday questions. He explores the nature of normativity--the reasoning behind certain beliefs and emotions about how we should behave--and offers a novel account of responsibility.
