I trust I need not offer this audience, gathered in the noble hall of this historic Inn--of "old Purpulei, Britain's ornament"--any apology for challenging its attention in this and two succeeding addresses to the genesis, formulation, and the fundamental political philosophy of the Constitution of the United States. The occasion gives me peculiar satisfaction, not only in the opportunity to thank my fellow Benchers of the Inn for their graciousness in granting the use of this noble Hall for this purpose, but also because the delivery of these addresses now enables me to be, for the moment, in fact as in honorary title a Bencher, or Reader, of this time-honoured society. If I needed any justification for addresses, which I was graciously invited to deliver under the auspices of the University of London, an honour which I also gratefully acknowledge, it would lie in the fact that we are to consider one of the supremely great achievements of the English-speaking race. It is in that aspect that I shall treat my theme; for, as a philosophical or juristic discussion of the American Constitution, my addresses will be neither as "deep as a well, nor as wide as a church door." My auditors will bear in mind that I must limit each address to the duration of an hour, and that I cannot go deeply or exhaustively into a subject that has challenged the admiring comment and profound consideration of the intellectual world for nearly a century and a half. If England and America are to act together in the coming time--and the destinies of the world are, to a very large extent, in their keeping, then they must know each other better, and, to this end, they must take a greater interest in each other's history and political institutions. My principal purpose in these lectures is to deepen the interest of this great nation in one of the very greatest and far-reaching achievements of our common race. Americans have never lacked interest in English history; for however broad the stream of our national life, how could we ignore its chief source?
