mysteries of temperament

It has sometimes crossed my mind that James wanted to be a poet and an artist, and that there lay in him, beneath the ocean of metaphysics, a lost Atlantis of the fine arts; that he really hated philosophy and all its works, and pursued them only as Hercules might spin, or as a prince in a fairy tale might sort seeds for an evil dragon, or as anyone might patiently do some careful work for which he had no aptitude. It would seem most natural, if this were the case between James and the metaphorical sciences; for what is there in these studies that can drench and satisfy a tingling mercurial being who loves to live on the surface, as well as in the depths of life? Thus we reason, forgetting that the mysteries of temperament are deeper than the mysteries of occupation.
