"The instinct which creates the arts is not the same as that which produces art. The creative instinct is, in its final analysis and in its simplest terms, an enormous extra vitality, a super-energy, born inexplicably in an individual, a vitality great beyond all the needs of his own living — an energy which no single life can consume. This energy consumes itself then in creating more life, in the form of music, painting, writing, or whatever is its most natural medium of expression. Nor can the individual keep himself from this process, because only by its full function is he relieved of the burden of this extra and peculiar energy — an energy at once physical and mental, so that all his senses are more alert and more profound than another man's, and all his brain more sensitive and quickened to that which his senses reveal to him in such abundance that actuality overflows into imagination. It is a process proceeding from within. It is the heightened activity of every cell of his being, which sweeps not only himself, but all human life about him, or in him, in his dreams, into the circle of its activity."
