Famous quotes containing the word mass:
“It is a mass language only in the same sense that its baseball slang is born of baseball players. That is, it is a language which is being molded by writers to do delicate things and yet be within the grasp of superficially educated people. It is not a natural growth, much as its proletarian writers would like to think so. But compared with it at its best, English has reached the Alexandrian stage of formalism and decay.”
—Raymond Chandler (1888–1959)
“Genius is present in every age, but the men carrying it within them remain benumbed unless extraordinary events occur to heat up and melt the mass so that it flows forth.”
—Denis Diderot (1713–1784)
“The most dangerous aspect of present-day life is the dissolution of the feeling of individual responsibility. Mass solitude has done away with any difference between the internal and the external, between the intellectual and the physical.”
—Eugenio Montale (1896–1981)
