Famous quotes containing the word expansion:

    Every expansion of government in business means that government in order to protect itself from the political consequences of its errors and wrongs is driven irresistibly without peace to greater and greater control of the nation’s press and platform. Free speech does not live many hours after free industry and free commerce die.
    Herbert Hoover (1874–1964)

    We are caught up Mr. Perry on a great wave whether we will or no, a great wave of expansion and progress. All these mechanical inventions—telephones, electricity, steel bridges, horseless vehicles—they are all leading somewhere. It’s up to us to be on the inside in the forefront of progress.
    John Dos Passos (1896–1970)

    Artistic genius is an expansion of monkey imitativeness.
    W. Winwood Reade (1838–1875)
