"Grok" ---

A made up word invented by Heinlen (sp ?) in Stranger in a Strange land. Means, best translated, as "fully understanding to an intuitive, gut level."

Thanks for the explanation. I'd think, however, that the study of history, to which the original post was referring, would be best done on a rational [rather than instinctive] level.
