First and Last

But apart from the importance of consulting original sources--which is like hearing the very witnesses themselves in court--there is a factor in historical judgment which by some unhappy accident is peculiarly lacking in the professional historian. It is a factor to which no particular name can be attached, though it may be called a department of common sense. But it is a mental power or attitude easily recognizable in those who possess it, and perhaps atrophied by the very atmosphere of the study. It goes with the open air with a general knowledge of men and with that rapid recognition of the way in which things "fit in" which is necessarily developed by active life.
