Eyes become used to darkness, and the light of brilliant day seems painful to the eyes grown long accustomed to the dim effects perceived at twilight. And they turn away from sunlight and the clarity it brings to what they look upon. Dimness seems better; easier to see, and better recognized. Somehow the vague and more obscure seems easier to look upon; less painful to the eyes than what is wholly clear and unambiguous. Yet this is not what eyes are for, and who can say that he prefers the darkness and maintain he wants to see?
