the element of time in politics, though it bears most directly upon the practicability of any constructive proposal. [Footnote: Cf . H. G. Wells in the opening chapters of Mankind in the Making. ] We can see, for example, that somehow the relevancy of any plan depends upon the length of time the operation requires. Because on the length of time it will depend whether the data which the plan assumes as given, will in truth remain the same. [Footnote: The better the current analysis in the intelligence work of any institution, the less likely, of course, that men will deal with tomorrow's problems in the light of yesterday's facts.] There is a factor here which realistic and experienced men do take into account, and it helps to mark them off somehow from the opportunist, the visionary, the philistine and the pedant. [Footnote: Not all, but some of the differences between reactionaries, conservatives, liberals, and radicals are due, I think, to a different intuitive estimate of the rate of change in social affairs.] But just how the calculation of time enters into politics we do not know at present in any systematic way.
