George Santayana,
Egotism in German Philosophy — Chapter XIII. The Superman
(1916)
“ Inspiration, like will, is a force without which reason can do nothing. Inspiration must be presupposed; but in itself it can do nothing good unless it is in harmony with reason, or is brought into harmony with it. This two-edged wisdom that makes impulse the stuff of life and reason its criterion, is, of course, lost on Nietzsche, and with it the whole marvel of Greek genius. ”
