W. Maitland's remarkable course of lectures provides the basic framework of English constitutional history in a brief, but original, scholarly and very readable form. His method is to take five crucial periods and to present in each a panoramic view of the processes of law and government; his attention is always fixed on the constitution as a growing fabric, as something devised and employed by live human beings. And in this work, as in all he subsequently wrote, Maitland shows a rare combination of high speculative power with exact knowledge of detail.
