Lloyd's Introduction to Jurisprudence is the leading textbook on jurisprudence in the English-speaking world. It enables the reader to develop a good understanding of the theories of the different schools of jurisprudence and to appreciate the contributions made to legal theory by leading jurists from the Ancient Greeks to the postmodernists. As ever, it combines text and extracts from authoritative sources. The works of more than a hundred jurists are extracted from Aristotle to the LatCrits. These are supported by detailed and well-documented introductory sections - a textbook in themselves - which give critical insight into the texts. Students and their teachers will profit from having in one book a wide-ranging compendium of legal thought. This new edition contains major new chapters on Theories of Justice and Critical Race Theory. There is substantial new writing in nearly every chapter, with greater emphasis on Hart (particularly the 'Postscript' and the commentary this has provoked), on Raz, Habermas and Unger. Amongst jurists extracted for the first time in this edition are Coleman, Perry, Kramer, Nelken, Iris Marion Young and Tamanaha.
