Famous quotes containing the words frame, aspect and/or ratios:
“The warped, distorted frame we have put around every Negro child from birth is around every white child also. Each is on a different side of the frame but each is pinioned there. And ... what cruelly shapes and cripples the personality of one is as cruelly shaping and crippling the personality of the other.”
—Lillian Smith (1897–1966)
“One ... aspect of the case for World War II is that while it was still a shooting affair it taught us survivors a great deal about daily living which is valuable to us now that it is, ethically at least, a question of cold weapons and hot words.”
—M.F.K. Fisher (1908–1992)
“Typography is not only a technology but is in itself a natural resource or staple, like cotton or timber or radio; and, like any staple, it shapes not only private sense ratios but also patterns of communal interdependence.”
—Marshall McLuhan (1911–1980)
