Samuel Taylor Coleridge,
Biographia Literaria; or, Biographical Sketches of My Literary Life and Opinions
(1817)
“ The sanity of the mind is between superstition with fanaticism on the one hand; and enthusiasm with indifference and a diseased slowness to action on the other. For the conceptions of the mind may be so vivid and adequate, as to preclude that impulse to the realizing of them, which is strongest and most restless in those, who possess more than mere talent, (or the faculty of appropriating and applying the knowledge of others) yet still want something of the creative, and self-sufficing power of absolute Genius. For this reason therefore, they are men of commanding genius. ”
