MY authority for attributing to Descartes the distinction between “creation” and “direction” is Leibniz's “Theodicée” (Erd. 519). I ought to have stated more clearly than I did that he, of course, conceived of the problem in the form in which it presented itself to his age as one of “motion” rather than of energy and momentum. In referring to the history of the discussion at all, I merely meant to indicate its antiquity. This, of course, is no reason why it should not be reopened now. Every generation of thinkers has to adjust old solutions to new forms of a problem. It is, however, a reason why we should inquire whether a controversy of so long a standing may not be founded on a radical misunderstanding.
