The most important and personally meaningful class I attended by at Yale was not presented by any Yale faculty member. It was by August Heckscher and delivered in Woolsey Hall in an one-time program, “Challenge.” We were, you will remember, at the tag-end of the “Silent Generation,” which started after WWII and ended more or less with us and with the realization that the truculence of The Soviet Union was challenging our quintessential American expectation that the rest of the world was going to leave us alone while we got along, thank you very much, with our orderly pursuits of the post-war domestic life. Heckscher, of course, put a stick of dynamite under our seats by examples of political agitations and Communist advances in the rest of the world. Who knew? I was deeply affected by that speech, and I believe that it was seminal in my life-long involvement of various kinds in international and global affairs.
