Famous quotes containing the words south american, south, american, failed, penetrate, central and/or america:
“I need not tell you of the inadequacy of the American shipping marine on the Pacific Coast.... For this reason it seems to me that there is no subject to which Congress can better devote its attention in the coming session than the passage of a bill which shall encourage our merchant marine in such a way as to establish American lines directly between New York and the eastern ports and South American ports, and both our Pacific Coast ports and the Orient and the Philippines.”
—William Howard Taft (1857–1930)
“The developments in the North were those loosely embraced in the term modernization and included urbanization, industrialization, and mechanization. While those changes went forward apace, the antebellum South changed comparatively little, clinging to its rural, agricultural, labor-intensive economy and its traditional folk culture.”
—C. Vann Woodward (b. 1908)
“The American landscape has no foreground and the American mind no background.”
—Edith Wharton (1862–1937)
“Psychology has nothing to say about what women are really like, what they need and what they want, essentially because psychology does not know.... this failure is not limited to women; rather, the kind of psychology that has addressed itself to how people act and who they are has failed to understand in the first place why people act the way they do, and certainly failed to understand what might make them act differently.”
—Naomi Weisstein, U.S. psychologist, feminist, and author. Psychology Constructs the Female (1969)
“It is a thorny undertaking, and more so than it seems, to follow a movement so wandering as that of our mind, to penetrate the opaque depths of its innermost folds, to pick out and immobilize the innumerable flutterings that agitate it. And it is a new and extraordinary amusement, which withdraws us from the ordinary occupations of the world, yes, even from those most recommended.”
—Michel de Montaigne (1533–1592)
“In a large university, there are as many deans and executive heads as there are schools and departments. Their relations to one another are intricate and periodic; in fact, “galaxy” is too loose a term: it is a planetarium of deans with the President of the University as a central sun. One can see eclipses, inner systems, and oppositions.”
—Jacques Barzun (b. 1907)
“... the Black woman in America can justly be described as a “slave of a slave.””
—Frances Beale, African American feminist and civil rights activist. The Black Woman, ch. 14 (1970)
