Famous quotes containing the words biological and/or material:
“In America every woman has her set of girl-friends; some are cousins, the rest are gained at school. These form a permanent committee who sit on each other’s affairs, who “come out” together, marry and divorce together, and who end as those groups of bustling, heartless well-informed club-women who govern society. Against them the Couple of Ehepaar is helpless and Man in their eyes but a biological interlude.”
—Cyril Connolly (1903–1974)
“We all drew on the comfort which is given out by the major works of Mozart, which is as real and material as the warmth given up by a glass of brandy.”
—Rebecca West (1892–1983)
