A man's work reveals him. In social intercourse he gives you the surface that he wishes the world to accept, and you can only gain a true knowledge of him by inferences from little actions, of which he is unconscious, and from fleeting expressions, which cross his face unknown to him. Sometimes people carry to such perfection the mask they have assumed that in due course they actually become the person they seem. But in his book or his picture the real man delivers himself defenceless.
