knowledgeable (person in many areas) n.: polyhistor
At the weekly salon [Srenus] Zeitblom encounters Dr. Chaim Breisacher. A Jew, he was also [according to Zeitblom] “a polyhistor, who could talk about anything and everything, a philosopher of culture, whose opinions, however, were directed against culture insofar as he affected to see all of history as nothing but a process of decline.” (Stephen Goode, “The Conscience of a Composer, and a Nation,” Washington Times, 4/5/1998.)
