John Randolph, erratic and bizarre, was not justly entitled to rank among great statesmen. But the characteristics of Congress, as a body, can be brought into better relief in the narrative of his life than in that of any other person of his day. These characteristics were so striking, so essential to an understanding of the history of those times, and so utterly different from the habits and ways of our own era, that an opportunity to present them must have been forced if Randolph had not fortunately offered it. These four volumes are mentioned by way of illustration of the plan of the series in some of its less obvious purposes. By the light of the suggestions thus afforded, readers will probably see for themselves the motives which have led to the presence of other volumes. But one further statement should be made. It has been the editor's intention to deal with the advancement of the country. When the people have moved steadily along any road, the men who have led them on that road have been selected as subjects. When the people have refused to enter upon a road, or, having entered, have soon turned back from it, the leaders upon such inchoate or abandoned excursions have for the most part been rejected. Those who have been exponents of ideas and principles which have entered into the progress and have developed in a positive way the history of the nation have been chosen; those who have unfortunately linked themselves with rejected ideas and principles have themselves also been rejected. Calhoun has been made an exception to this rule, for reasons so obvious that they need not be rehearsed.
