This work for the first time brings together case law and law based on norms. It offers the reader a survey and a new explanation of evolutionary emergence of social contracts and constitutions in the European history, and should help to build a bridge between 'two cultures', science and humanities. It is addressed to philosophers of law, historians of law, theorists of science and social scientists.
