The thinker has signalled the importance of exploring modern legal theory to our understanding of democratic society.;This volume provides an introduction to this key development in Habermas' work. With chapters ranging from the possibility of valid law to discourse ethics and human rights, the author successfully integrate a broad range of Habermas' writings with his most recent thoughts on the place of the law in contemporary theory. The author himself contributes a postscript to the book, providing an overview of the current thinking.
