Famous quotes containing the word key:

    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.
    HonorĂ© De Balzac (1799–1850)

    In that Kingdom is a city;
    —Unknown. This Is the Key (l. 1–2)

    With one day’s reading a man may have the key in his hands.
    Ezra Pound (1885–1972)
