text: This is not true; for no real rest can be found when reason has not done the lulling. Night brings our troubles to the light, rather than banishes them; it merely changes the form of our worries. For even when we seek slumber, our sleepless moments are as harassing as the daytime. Real tranquillity is the state reached by an unperverted mind when it is relaxed. Think of the unfortunate man who courts sleep by surrendering his spacious mansion to silence, who, that his ear may be disturbed by no sound, bids the whole retinue of his slaves be quiet and that whoever approaches him shall walk on tiptoe; he tosses from this side to that and seeks a fitful slumber amid his frettings! He complains that he has heard sounds, when he has not heard them at all. The reason, you ask? His soul is in an uproar; it must be soothed, and its rebellious murmuring checked. You need not suppose that the soul is at peace when the body is still. Sometimes quiet means disquiet.
