"At most times it lies far in the back of my mind, a mere distant cloud, a memory, and a faint distrust; but there are times when the little cloud spreads until it obscures the whole sky. Then I look about me at my fellow-men; and I go in fear. I see faces, keen and bright; others dull or dangerous; others, unsteady, insincere,—none that have the calm authority of a reasonable soul." (The Island of Dr. Moreau, H.G. Wells)
