In this age of collections that is ours, many volumes of collections are published. They contain contributions of several well-known authors, and their aim is to present a selective overview of a relevant field of study. This book has the same purpose. Its aim is to introduce students, scholars and all those interested in current problems of legal theory and legal philosophy to the work of the leading scholars in this field. The large number of publications, both books and articles, that have been produced over recent decades makes it quite difficult, however, for those who are making their first steps in this domain to find firm guidelines. The book is new in its genre because of its method. The choice was made not to reprint an example of contributors' earlier basic articles or a part of one of their books. This would only give a partial view of the rich texture of their work. Rather, the authors were asked to make an original synthesis of their own contributions to the field of legal theory and legal philosophy. Brought together in this volume, they constitute a truly author-ised view of their work. This book is also new in that each essay is complemented with bibliographical information in order to encourage further research on the author's self-selected work. This will help the reader rapidly to become familiar with the whole of the published work of the contributors.
