Brighter possibilities for a more lasting world peace after this war were describing last night by Hans Kohn, visiting professor in Government, in a talk to a group of 40 College and Radcliffe students. His talk, "The Lessons to Be Learned from Versailles," opened a series to be conducted by the "America's Role in World Affairs" division of the Post-War Council.

"Wars," Professor Kohn said, "have many purposes, but only one cause, that being self-defense." A better peace can only be built around the realization that the United States has been fighting a war for survival, and not a crusade, the lecturer said.

Pointing out that the American public after the last war had been hurt very little, with comparatively few causalities, Professor Kohn expressed little fear that a similar state of public opinion would exist at the close of the present war. Well over a million causalities, and a resultant economic depression, will hardly let the American public slide into a rose-colored view of world happenings he added.

With favorable American public opinion, and the realization that a war for survival has been fought, in back of the peacemakers, Professor Kohn predicted that a more lasting peace, possibly opening an era of universal good will, would come out of the post-war settlement.
