Perhaps I have said enough to show the part which the study of history necessarily plays in the intelligent study of the law as it is today. In the teaching of this school and at Cambridge it is in no danger of being undervalued. Mr. Bigelow here and Mr. Ames and Mr. Thayer there have made important contributions which will not be forgotten, and in England the recent history of early English law by Sir Frederick Pollock and Mr. Maitland has lent the subject an almost deceptive charm. We must beware of the pitfall of antiquarianism, and must remember that for our purposes our only interest in the past is for the light it throws upon the present. I look forward to a time when the part played by history in the explanation of dogma shall be very small, and instead of ingenious research we shall spend our energy on a study of the ends sought to be attained and the reasons for desiring them. As a step toward that ideal it seems to me that every lawyer ought to seek an understanding of economics. The present divorce between the schools of political economy and law seems to me an evidence of how much progress in philosophical study still remains to be made. In the present state of political economy, indeed, we come again upon history on a larger scale, but there we are called on to consider and weigh the ends of legislation, the means of attaining them, and the cost. We learn that for everything we have we give up something else, and we are taught to set the advantage we gain against the other advantage we lose, and to know what we are doing when we elect.
