“... goodness is of a modest nature, easily discouraged, and when much elbowed in early life by unabashed vices, is apt to retire into extreme privacy, so that it is more easily believed in by those who construct a selfish old gentleman theoretically, than by those who form the narrower judgments based on his personal acquaintance.”
—George Eliot [Mary Ann (or Marian)
“It was announced that the trouble was not malignant.... It was a typical triumph of modern science to find the only part of Randolph that was not malignant and remove it.”
—Evelyn Waugh (19031966)
“The easiest period in a crisis situation is actually the battle itself. The most difficult is the period of indecisionwhether to fight or run away. And the most dangerous period is the aftermath. It is then, with all his resources spent and his guard down, that an individual must watch out for dulled reactions and faulty judgment.”
—Richard M. Nixon (19131995)
