It is essential that this fundamental fallacy in the use of statistics should be got somehow into the modern mind. Such people must be made to see the point, which is surely plain enough, that it is useless to have exact figures if they are exact figures about an inexact phrase. If I say, "There are five fools in Action," it is surely quite clear that, though no mathematician can make five the same as four or six, that will not stop you or anyone else from finding a few more fools in Action.
