This book grew out of the conviction that the original concepts of the Poznań School of Legal Theory are still perfectly suited for application today, in the era of moral pluralism and multicentric legal systems. Moreover, since we are in the midst of a period of heated disputes over the grounds of the normativity of law, and are confronting controversies about the basis for the legitimacy of court decisions, over the results of legal interpretation, and concerning the coherence of legal (...) systems, it would seem that the legal-theoretical proposals put forward by the circle of Poznań legal theorists, supported as they are by firm methodological foundations, have not by any means lost their value.
