It is this which has inspired the great musicians and poets. Why do the music of Wagner or Beethoven and the words of Shakespeare live so long and continually give new joy and inspiration? Why has not all music and poetry the same effect? Because poetry is one thing, and the dance of the soul another. The dance of the soul is beyond mere poetry, and when music expresses itself as the dance of the soul it becomes something higher than music. Man becomes so accustomed to external knowledge! He wants to learn and understand this thing and that, but beauty does not come so naturally because beauty is beyond all knowledge: it is intended to prepare man to express his soul.
