Lord Jim

"The danger, when not seen, has the imperfect vagueness of human thought.  The fear grows shadowy; and Imagination, the enemy of men, the father of all terrors, unstimulated, sinks to rest in the dullness of exhausted emotion.  Jim saw nothing but the disorder of his tossed cabin...

But now and again an uncontrollable rush of anguish would grip him bodily, make him gasp and writhe under the blankets, and then the unintelligent brutality of existence liable to the agony of such sensations filled him with a despairing desire to escape at any cost.  Then fine weather returned, and he thought no more about it."
