In short, all good things are wild and free. There is something in a strain of music, whether produced by an instrument or by the human voice — take the sound of a bugle in a summer night, for instance, — which by its wildness, to speak without satire, reminds me of the cries emitted by wild beasts in their native forests. It is so much of their wildness as I can understand. Give me for my friends and neighbors wild men, not tame ones. The wildness of the savage is but a faint symbol of the awful ferity with which good men and lovers meet.
