Original Quote: We assert then that nothing has been accomplished without interest on the part of the actors; and — if interest be called passion, inasmuch as the whole individuality, to the neglect of all other actual or possible interests and claims, is devoted to an object with every fibre of volition, concentrating all its desires and powers upon it — we may affirm absolutely that nothing great in the World has been accomplished without passion.
