More attention has been given to the changes of view among radicals than to those which have taken place among conservatives. Since events of recent years have greatly encouraged self-expression on the part of misinformed noisy extremists who appoint themselves spokesmen of the latter group, we sometimes get the impression that conservatives learn nothing. But I incline to the opinion that there has been perhaps an equal proportion of learning by the more thoughtful minority on both sides of the controversy. Among radicals modification of views has occurred sufficiently to arouse general interest in the questions “What has become of the pre-war liberals?” “What has happened to radicalism?” A former member of the radical group some years ago wrote a book entitled “Tired Radicals,” in which he adopted the usual view that the change of outlook among radicals was the result of the loss of energy and enthusiasm which comes with middle age. But if radicalism were merely a form of youthful enthusiasm, I believe the movement would be more wide-spread than it has ever been in America. The suggestion is worth considering that in some cases the change of views might indicate that the individual has learned something. By learning I mean the better grasp of the subject which comes when one examines the presuppositions of both sides. Conversely, those who have not examined their presuppositions during the last twenty years have learned nothing. They continue talking, but they are addressing a generation that is past and gone. Anachronisms of this sort are common occurrences among conservatives. They occur with equal frequency among radicals. And when a man whose education has stopped leaves the radical movement and joins the opposition, he frequently shows himself to be not an aging prophet who has lost his enthusiasms, but the same intensely opinionated and militant person he was before.
