I no longer believe that most traditional historians are emotionally equipped, even with training, to use their feelings as psychohistorical research tools, although there is a whole new generation of psychohistorians just now beginning to write who are able to do so. To expect the average historian to do psychohistory is like trying to teach a blind man to be an astronomer [...]. Whenever I speak to a scholar of the emotional development necessary to make a good psychohistorian and get a blank look of total incomprehension, I try to find a way to leave the subject of psychohistory altogether. My listener usually is in another world of discourse where emotional reactions are not considered crucial to the results.
