Famous quotes containing the word key:

    “At the last, tenderly,
    From the walls of the powerful fortress’d house,
    From the clasp of the knitted locks, from the keep of the well-closed doors,
    Let me be wafted.

    Let me glide noiselessly forth;
    With the key of softness unlock the locks—with a whisper,
    Set ope the doors O soul.”
    —Walt Whitman (1819–1892)

    “Now narrow minds can develop as well through persecution as through benevolence; they can assure themselves of their power by tyrannizing cruelly or beneficently over others; they go the way their nature guides them. Add to this the guidance of interest, and you will have the key to most social riddles.”
    —Honoré De Balzac (1799–1850)

    “The knight slew the dragon,
    The lady was gay,
    They rode on together,
    Away, away.”
    —Unknown. This Is the Key (l. 38–41)
