Famous quotes containing the words large and/or systems:
“... in 1950 a very large slice of the white South stood at the crossroads in its attitude toward its colored citizens and [was] psychologically capable of turning either way.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 8 (1962)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Gray’s Anatomy.”
—J.G. (James Graham)
