Famous quotes containing the words effective and/or dates:
“Fine art is the subtlest, the most seductive, the most effective instrument of moral propaganda in the world, excepting only the example of personal conduct; and I waive even this exception in favor of the art of the stage, because it works by exhibiting examples of personal conduct made intelligible and moving to crowds of unobservant unreflecting people to whom real life means nothing.”
—George Bernard Shaw (1856–1950)
“We do NOT know the past in chronological sequence. It may be convenient to lay it out anesthetized on the table with dates pasted on here and there, but what we know we know by ripples and spirals eddying out from us and from our own time.”
—Ezra Pound (1885–1972)
