As I set out to prepare for this combined inaugural and valedictory, I sought a theme worthy of the occasion and within the span of my own limited vision. Notwithstanding the lush crop of “problems” confronting our world and our profession, no suitable theme came readily to mind. I experimented with many, including “Variations on a Theme by Joe McCarthy,” or “Acheson at Armageddon,” or “General MacArthur Fades Again.” But in all such cases the theme was obscured by the variations. And so I've called these remarks “Variations on a Familiar Theme.”

Since 1903 when Frank Goodnow spoke on “The Work of the American Political Science Association,” no less than forty-five presidents have prepared annual speeches on as many different themes. It is interesting to note that of thirteen such speeches up to 1917, only one gave any major attention to international relations. Then, between 1917 and 1924, four of the seven were devoted to an international theme. But during the twenty-six years from 1924 through 1950, only two dealt primarily with international relations.
