It begins with the earliest writings in natural law theory and positivism, tracing the history of the debate through the Hart-Fuller and Hart-Dworkin disputes to the current debates. The last third of the volume is devoted to the most influential papers on the hottest contemporary issues. The approach is analytic and hands-on. It seeks to motivate interest in foundational questions of law while simultaneously developing the skills the aspiring lawyer must have to succeed in the practice of law. To develop the student's ability to theorize on questions in analytic jurisprudence by providing a firm historical foundation before immersing her in the contemporary debates, where she will participate in the conversation. The book improves on existing text offerings in a number of respects. It provides the most comprehensive view of the field. The analytic approach is ascendant among researchers in law schools and philosophy departments worldwide who study the issues covered in this text. Accordingly, it is fair to say that this book provides, far and away, the most up-to-date and accurate snapshot of the work being done in conceptual issues regarding law so much so that it is suitable for use as a sourcebook for beginning research.
