Famous quotes containing the word prime:
“The prime lesson the social sciences can learn from the natural sciences is just this: that it is necessary to press on to find the positive conditions under which desired events take place, and that these can be just as scientifically investigated as can instances of negative correlation. This problem is beyond relativity.”
—Ruth Benedict (1887–1948)
“What was lost in the European cataclysm was not only the Jewish past—the whole life of a civilization—but also a major share of the Jewish future.... [ellipsis in source] It was not only the intellect of a people in its prime that was excised, but the treasure of a people in its potential.”
—Cynthia Ozick (b. 1928)
“By whatever means it is accomplished, the prime business of a play is to arouse the passions of its audience so that by the route of passion may be opened up new relationships between a man and men, and between men and Man. Drama is akin to the other inventions of man in that it ought to help us to know more, and not merely to spend our feelings.”
—Arthur Miller (b. 1915)
