QU684Y Dart Oetober 7, 1974 © Dr. Judith Shklar, — Department of Government Harvard University Cambridge, Mass. 02138 Dear Dr. Shklar, I note your recent critique of Henry Adams in Daedalus. Are you informed of the history of the idea of acceleration?* I would have thought that exponential economic growth shaped by compound interest went back to antiquity. But I have found little reference fo idea that exponential * explosive before Malthus. And Adams seems to have seized on the geometric series as if it were a new frame of thinking in its application to human affairs. Sincerely yours, Joshua Lederberg Professor of Genetics *cf D.
