For the thinkers of that school disregard the question whether a possibility, once entertained, may seem one day to correspond to some meagre arrangement of events. They give all their attention to the possibility itself and esteem it according to its amplitude and to the length of time for which it survives just beyond reach of the haphazard disposition of sights and sounds which is called, in careless speech, actuality, and has been considered, perhaps even by a few plainsmen, to represent the extinction of all possibilities.
