Famous quotes containing the words north america, america, western and/or north:

    The compulsion to do good is an innate American trait. Only North Americans seem to believe that they always should, may, and actually can choose somebody with whom to share their blessings. Ultimately this attitude leads to bombing people into the acceptance of gifts.
    Ivan Illich (b. 1926)

    I sincerely hope that the incoming Congress will be alive, as it should be, to the importance of our foreign trade and of encouraging it in every way feasible. The possibility of increasing this trade in the Orient, in the Philippines, and in South America is known to everyone who has given the matter attention.
    William Howard Taft (1857–1930)

    In everyone’s youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.
    Henry David Thoreau (1817–1862)

    New York is a meeting place for every race in the world, but the Chinese, Armenians, Russians, and Germans remain foreigners. So does everyone except the blacks. There is no doubt but that the blacks exercise great influence in North America, and, no matter what anyone says, they are the most delicate, spiritual element in that world.
    Federico García Lorca (1898–1936)
