This unique book presents various ways in which evolutionary theory can contribute to the analysis of key legal-philosophical problems.Wojciech Zaluski explores three central questions; the ontological question - what is the nature of law?; the teleological-axiological question - what are the main values to be realized by law?; the normativity question, which has two aspects; normative: what explains the fact that legal norms provide reasons for action?, and motivational: what explains the fact that humans can be motivated by legal norms? It is argued that evolutionary theory suggests non-trivial answers to these questions, and that these answers can become the building blocks of a new - evolutionary - paradigm in legal philosophy.

Being the first study entirely devoted to the analysis of fundamental legal-philosophical problems from the standpoint of evolutionary theory, this book is a must-read for graduate and postgraduate students, practitioners and philosophers in the field of legal philosophy.
