Context: The life, the fortune, and the happiness of every one of us, and, more or less, of those who are connected with us, do depend upon our knowing something of the rules of a game infinitely more difficult and complicated than chess. It is a game which has been played for untold ages, every man and woman of us being one of the two players in a game of his or her own. The chessboard is the world, the pieces are the phenomena of the universe, the rules of the game are what we call the laws of Nature. The player on the other side is hidden from us. We know that his play is always fair, just, and patient. But also we know, to our cost, that he never overlooks a mistake, or makes the smallest allowance for ignorance. To the man who plays well, the highest stakes are paid, with that sort of overflowing generosity with which the strong shows delight in strength. And one who plays ill is checkmated — without haste, but without remorse.

Context: String theory is extremely attractive because gravity is forced upon us. All known consistent string theories include gravity, so while gravity is impossible in quantum field theory as we have known it, it is obligatory in string theory.

Context: There is survival and survival, the historian learns to his grief. The very worst impulses of humankind can survive generations, centuries, even millennia. And the best of our individual efforts can die with us at the end of a single lifetime.
Context: My dear and unfortunate successor:
I shall conclude my account as rapidly as possible, since you must draw from it vital information if we are both to — ah, to survive, at least, and to survive in a state of goodness and mercy. There is survival and survival, the historian learns to his grief. The very worst impulses of humankind can survive generations, centuries, even millennia. And the best of our individual efforts can die with us at the end of a single lifetime.
