Famous quotes containing the words engine, serial, number and/or codes:

    “The will is never free—it is always attached to an object, a purpose. It is simply the engine in the car—it can’t steer.”
    —Joyce Cary (1888–1957)

    “An autobiography is an obituary in serial form with the last instalment missing.”
    —Quentin Crisp (b. 1908)

    “I think, for the rest of my life, I shall refrain from looking up things. It is the most ravenous time-snatcher I know. You pull one book from the shelf, which carries a hint or a reference that sends you posthaste to another book, and that to successive others. It is incredible, the number of books you hopefully open and disappointedly close, only to take down another with the same result.”
    —Carolyn Wells (1862–1942)

    “... until both employers’ and workers’ groups assume responsibility for chastising their own recalcitrant children, they can vainly bay the moon about “ignorant” and “unfair” public criticism. Moreover, their failure to impose voluntarily upon their own groups codes of decency and honor will result in more and more necessity for government control.”
    —Mary Barnett Gilson (1877–?)
