ance to his work. The space allotted in the Third and Fourth Chapters to certain philosophical theories of the Roman Jurisconsults, has been appropriated to them for two reasons. In the first place, those theories appear to the author to have had a much wider and more permanent influence on the thought and action of the world than is usually supposed. Secondly, they are believed to be the ultimate source of most of the views which have been prevalent, till quite recently, on the subjects treated of in this volume. It was impossible for the author to proceed far with his undertaking, without stating his opinion on the origin, meaning, and value of those speculations.
