“Why must the preying lion still become a child?” Nietzsche asks. “The child is innocence and forgetting, a new beginning, a game, a self-propelled wheel, a first movement, a sacred Yes. For the game of creation, my brothers, a sacred Yes is needed: the spirit now wills his own will.”
The child is innocent and creative, and is not self-conscious about its creativity. It puts together ideas and concepts in a way that has been
bred out of most adults.
In a different context, one of my favorite Nietzsche quotes: “Man's maturity: to have regained the seriousness that he had as a child at play.”
