“The Daemonic is that which cannot be accounted for by understanding and reason.... In Poetry there is from first to last something daemonic, and especially in its unconscious appeal, for which all intellect and reason is insufficient, and which, therefore, has an efficacy beyond all concepts. Such is the effect in Music to the highest degree, for Music stands too high for any understanding to reach, and an all-mastering efficacy goes forth from it, of which, however, no man is able to give an account. Religious worship therefore cannot do without music. It is one the foremost means to work upon men with an effect of marvel.”
