Famous quotes containing the words formal, system, based and/or stroke:

    Social and scientific progress are assured, sir, once our great system of postpossession payments is in operation, not the installment plan, no sir, but a system of small postpossession payments that clinch the investment. No possible rational human wish unfulfilled. A man with a salary of fifty dollars a week can start payments on a Rolls-Royce, the Waldorf-Astoria, or a troupe of trained seals if he so desires.
    John Dos Passos (1896–1970)

    “Next time,” said the Inventor, “a woman will be added. Beauty is easy to render because beauty is based on the rendering of beauty, but we are still working on her hips, we want her to roll them, and that is difficult.”

    What can she know until He bid her know!
    How can she live till in her blood He live!
    William Butler Yeats (1865–1939)
