Famous quotes containing the words chemical and/or test:
“We are close to dead. There are faces and bodies like gorged maggots on the dance floor, on the highway, in the city, in the stadium; they are a host of chemical machines who swallow the product of chemical factories, aspirin, preservatives, stimulant, relaxant, and breathe out their chemical wastes into a polluted air. The sense of a long last night over civilization is back again.”
—Norman Mailer (b. 1923)
“The test of literature is, I suppose, whether we ourselves live more intensely for the reading of it.”
—Elizabeth Drew (1887–1965)
