In 1867 Mark Twain in a letter to the Alta California wrote the following:“I am thankful that the good God creates us all ignorant. I am glad that when we change His plans in this regard, we have to do it at our own risk. It is a gratification to me to know that I am ignorant of art, and ignorant also of surgery. Because people who understand art find nothing in pictures but blemishes, and surgeons and anatomists see no beautiful women in all their lives, but only a ghastly stack of bones with Latin names to them, and a network of nerves and muscles and tissues inflamed by disease.
