ABSTRACT
Psychology stops just where things begin to become interesting: its account glosses over the distinction between accredited entities and bogus entities, and it provides no criterion by which such may be judged: it is too inclined to adopt circular procedures. The psychological basis of our belief in the 'flight' of time and the 'irreversibility' of time are not far to seek: it is to be found ultimately in the moment of experience, with its transition from present to past. The psychologist pleads extremity, and urges that a genetic explanation is bound to be in terms of the highest level. The 'time' of experience has one great drawback in a gregarious world. It is private, and varies with the subject. The conventionalizing of duration is inevitable if we are to live peaceably with our fellows, to prevent unnecessary disputes and uncertainties and waste of time.
