History and geography
History and geography are the building blocks of learning, according to Victor Davis Hanson. "Without awareness of natural and human geography, we are reduced to a sort of self-contained void without accurate awareness of the space around us. An ignorance of history also creates the same sort of self-imposed exile, leaving us ignorant of both what came before us and what is likely to follow."
"The study of history is a powerful antidote to contemporary arrogance. It is humbling to discover how many of our glib assumptions, which seem to us novel and plausible, have been tested before, not once but many times and in innumerable guises; and discovered to be, at great human cost, wholly false." (Paul Johnson)
