Blessed influence of one true loving human soul on another! Not calculable by algebra, not deducible by logic, but mysterious, effectual, mighty as the hidden process by which the tiny seed is quickened, and bursts forth into tall stem and broad leaf, and glowing tasselled flower. Ideas are often poor ghosts; our sun-filled eyes cannot discern them; they pass athwart us in thin vapor, and cannot make themselves felt. But sometimes they are made flesh; they breathe upon us with warm breath, they touch us with soft responsive hands, they look at us with sad sincere eyes, and speak to us in appealing tones; they are clothed in a living human soul, with all its conflicts, its faith, and its love. Then their presence is a power, then they shake us like a passion, and we are drawn after them with gentle compulsion, as flame is drawn to flame.
— George Eliot, a.k.a. Mary Ann Evans (1819-1880)
