Hermann Hesse said this quote

The “music of decline” had sounded, as in that wonderful Chinese fable; like a thrumming bass on the organ its reverberations faded slowly out over decades; its throbbing could be heard in the corruption of the schools, periodicals, and universities, in melancholia and insanity among those artists and critics who could still be taken seriously; it raged as untrammeled and amateurish overproduction in all the arts.
