Famous quotes containing the word paper:
“I blame the newspapers because every day they call our attention to insignificant things, while three or four times in our lives, we read books that contain essential things. Once we feverishly tear the band of paper enclosing our newspapers, things should change and we should find—I do not know—the Pensées by Pascal!”
—Marcel Proust (1871–1922)
