Abstract :
In an address reported in a recent issue of Vital Speeches of the Day W. F. G. Swann, director of the Bartol Research Foundation of the Franklin Institute, Swarthmore, Pa., discussed the problem of the use of leisure that has been made available by the accomplishments of science. Although warning that it is difficult to appraise the present in relation to the past and future, Doctor Swann pointed out that one who views the world today cannot escape the impression that the change man has seen in the last hundred years does not find its counterpart in any like period of the world´s history.
