"Mark Murphy is the most interesting and original natural law theorist of his generation, and this wide-ranging, learned, and lucid introduction to legal philosophy will be the text of choice for any student or philosopher who wants a philosophically sophisticated survey of the major topics that, at the same time, makes clear the continuing attraction of the natural law tradition." Brian Leiter, University of Texas at Austin "Murphy executes a masterly and enlightening challenge to fashionable claims that ‘all is not well’ with the law and its philosophy. Fully accessible to general audiences, his book will also inform and engage the specialist reader."William A. Edmundson, Georgia State University "Philosophy of Law itself is a well designed book on several levels ... Murphy hooks you from the start."Stuart Hannabuss, Aberdeen Buisness School, Robert Gordon University “A concise, well balanced, and articulate discussion. The author has the capacity to present complex material with ease to its audience… A highly captivating interpretation of the philosophy of law”Internet Law Book Reviews
