"You have delivered up our holy German Fatherland to one of the greatest demagogues of all time. I solemnly prophesy that this accursed man will cast our Reich into the abyss and bring our nation to inconceivable misery. Future generations will damn you in your grave for what you have done."
What are the facts? Again and again and again—what are the facts? Shun wishful thinking, ignore divine revelation, forget what "the stars foretell," avoid opinion, care not what the neighbors think, never mind the unguessable "verdict of history"; what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your single clue. Get the facts!
Robert Heinlein (1907 - 1988)
