In America I was liberated from a certain naïve belief in culture and attained the capacity to see culture from the outside. To clarify the point: in spite of all social criticism and all consciousness of the primacy of economic factors, the fundamental importance of the mind— Geist —was quasi a dogma self-evident to me from the very beginning. The fact that this was not a foregone conclusion, I learned in America, where no reverential silence in the presence of everything intellectual prevailed.
