Lawyers who write about responsibility tend to focus on criminal law at the expense of civil and public law; while philosophers tend to treat responsibility as a moral concept,and either ignore the law or consider legal responsibility to be a more or less distorted reflection of its moral counterpart. This book aims to counteract both of these biases. By adopting a comparative institutional approach to the relationship between law and morality, it challenges the common view that morality stands to law as critical standard to conventional practice. It shows how law and morality interact symbiotically, and how careful study of legal concepts of responsibility can add significantly to our understanding of responsibility more generally. At the heart of this book lie two questions: what does it mean to say we are responsible? And, what are our responsibilities? Its aim is not to answer these questions but to challenge some traditional approaches to answering them and more importantly, to suggest fruitful alternative approaches that take law seriously.
