"There’s nothing as significant as a human face. Nor as eloquent. We can never really know another person, except by our first glance at him. Because, in that glance, we know everything. Even though we’re not always wise enough to unravel the knowledge… I think, Kiki, that every human soul has a style of its own, also. Its one basic theme. You’ll see it reflected in every thought, every act, every wish of that person. The one absolute, the one imperative in that living creature. Years of studying a man won’t show it to you. His face will. You’d have to write volumes to describe a person. Think of his face. You need nothing else… It’s worse than that. It also leaves you naked before them. You betray yourself by the manner in which you react to a certain face… The style of your soul… There’s nothing important on earth, except human beings. There’s nothing as important about human beings as their relations to one another…"
