'to the gifts of nature are added the benefits of artifice'

... I take cognizance of the existence of elemental natural sounds, the raw materials of music, which, pleasing in themselves, may caress the ear and give us a pleasure that may be quite complete. But over and beyond this passive enjoyment we shall discover music, music that will make us participate actively in the working of a mind that orders, gives life, and creates. For at the root of all creation one discovers an appetite that is not an appetite for the fruits of the earth. So that to the gifts of nature are added the benefits of artifice—such is the general significance of art.

—Igor Stravinsky, Poetics of Music (1942) (trans. A. Knodel & I. Dahl 1947)
