The very point in a picture that fascinates me with its beauty, is to the cultured artist a monstrous crime against the laws of coloring; and the very flush that charms me in a lovely face, is, to the critical surgeon, nothing but a sign hung out to advertise a decaying lung. Accursed be all such knowledge. I want none of it. — Mark Twain, Letter to the San Francisco Alta California, May 28, 1867
