"To any artist, worthy of the name, all in nature is beautiful, because his eyes, fearlessly accepting all exterior truth, read there, as in an open book, all the inner truth. He has only to look into a human face in order to read there the soul within — not a feature deceives him; hypocrisy is as transparent as sincerity — the line of a forehead, the least lifting of a brow, the flash of an eye, reveal to him all the secrets of a heart."
