Sleep
"More than one hundred years ago, Tocqueville commented, as did other students of America at that time, that self-indulgence accompanied by concern for nothing except personal materialistic welfare was the major menace to America's future. Whitehead noted in Adventures of Ideas that 'The enjoyment of power is fatal to the subtleties of life. Ruling classes degenerate by reason of their lazy indulgence in obvious gratifications.' In such a state men may be said to fall asleep, for it is in sleep that we each turn away from the world about us to our private worlds."
- Saul Alinsky in Rules for Radicals
