Now I know That twenty centuries of stony sleep Were vexed to nightmare by a rocking cradle, And what rough beast, its hour come round at last, Slouches towards Bethlehem to be born?
We rest; a dream has power to poison sleep. We rise; one wand'ring thought pollutes the day. We feel, conceive, or reason; laugh or weep, Embrace fond woe, or cast our cares away; It is the same: for, be it joy or sorrow, The path of its departure still is free. Man's yesterday may ne'er be like his morrow; Nought may endure but Mutability!
I honor health as the first muse, and sleep as the condition of health. Sleep benefits mainly by the sound health it produces; incidentally also by dreams, into whose farrago a divine lesson is sometimes slipped.
I could not sleep when I got on such a hunt for an idea until I had caught it; ...This was a kind of passion with me, and it has stuck by me; for I am never easy now, when I am handling a thought, till I have bounded it north, and bounded it south, and bounded it east, and bounded it west.
Sleep takes off the costume of circumstance, arms us with terrible freedom, so that every will rushes to deed. A skillful man reads his dreams for his self-knowledge; yet not the details, but the quality. What part does he play in them - a cheerful, manly part, or a poor, drivelling part? However monstrous and grotesque their apparitions, they have a substantial truth.
A few hours' mountain climbing make of a rogue and a saint two fairly equal creatures. Tiredness is the shortest path to equality and fraternity - and sleep finally adds to them liberty.
Individually, men may present a more or less rational appearance, eating, sleeping, and scheming. But humanity a a whole is changeful, mystical, fickle, delightful. Men are men, but Man is a woman.
