One crucial thing about history is analysis. This is where you get into trouble with all the leftist professors.
Why 's there a problem specifically with leftist professors?
Anyway, isn't history just a projection of the past molded in the present by a number of different epistemological approaches, as well as inherent predisposition to temporal and causative order and relations?
If that holds some truth then why not use as many methodological tools as possible and avoid a stance that promotes exclusion and not composition?
