Famous quotes containing the words security and/or services:

    There is one safeguard known generally to the wise, which is an advantage and security to all, but especially to democracies as against despots. What is it? Distrust.
    Demosthenes (c. 384–322 B.C.)

    Men will say that in supporting their wives, in furnishing them with houses and food and clothes, they are giving the women as much money as they could ever hope to earn by any other profession. I grant it; but between the independent wage-earner and the one who is given his keep for his services is the difference between the free-born and the chattel.
    Elizabeth M. Gilmer (1861–1951)
