Famous quotes containing the word mass:
“They’re semiotic phantoms, bits of deep cultural imagery that have split off and taken on a life of their own, like those Jules Verne airships that those old Kansas farmers were always seeing.... Semiotic ghosts. Fragments of the Mass Dream, whirling past in the wind of my passage.”
—William Gibson (b. 1948)
“It is almost impossible to be a doctor and an honest man, but it is obscenely impossible to be a psychiatrist without at the same time bearing the stamp of the most incontestable madness: that of being unable to resist that old atavistic reflex of the mass of humanity, which makes any man of science who is absorbed by this mass a kind of natural and inborn enemy of all genius.”
—Antonin Artaud (1896–1948)
“I am not a very sentimental man; and the best sentiment I can think of is, that if you collect the signatures of all persons who are no less distinguished than I, you will have a very undistinguishing mass of names.”
—Abraham Lincoln (1809–1865)
