R.C. Van Caenegem is the successor of Henri Pirenne and of F.L. Ganshof at the University of Ghent. These essays reflect Van Caenegem's main interests over his career: the Common Law in England and Customary Law in the Low Countries; the differences between institutional development in England and in the rest of Europe; and the forces making for autocratic as opposed to representative government. A number of pieces discuss the nature of history itself: how it compares with the sciences and what it can teach us. Two essays commemorate the lives and work of Pirenne and Ganshof.
