Illustrated London News (1924)
Context: The whole modern world has divided itself into Conservatives and Progressives. The business of Progressives is to go on making mistakes. The business of Conservatives is to prevent mistakes from being corrected. Even when the revolutionist might himself repent of his revolution, the traditionalist is already defending it as part of his tradition. Thus we have two great types — the advanced person who rushes us into ruin, and the retrospective person who admires the ruins. He admires them especially by moonlight, not to say moonshine. Each new blunder of the progressive or prig becomes instantly a legend of immemorial antiquity for the snob. This is called the balance, or mutual check, in our Constitution.

1977

Sun Tzu among many other military thinkers and leaders believed in fate and determination from the correct application of theory, the state of the opponent's and one's own power, and a code for the general and a code for the soldier to follow, rather than the Machiavellian type of intuition that evokes an evolution of opportunism that brought great historical consequences as it dominated over the classical and medieval ethical doctrines. Thus this statement is contrary to Sun Tzu principles. Nevertheless, there is a possible relation to the quote: Quickness is the essence of the war.
