Famous quotes containing the words working and/or fluid:

    Asking a working writer what he thinks about critics is like asking a lamp-post what it feels about dogs.
    Christopher Hampton (b. 1946)

    In place of a world, there is a city, a point, in which the whole life of broad regions is collecting while the rest dries up. In place of a type-true people, born of and grown on the soil, there is a new sort of nomad, cohering unstably in fluid masses, the parasitical city dweller, traditionless, utterly matter-of-fact, religionless, clever, unfruitful, deeply contemptuous of the countryman and especially that highest form of countryman, the country gentleman.
    Oswald Spengler (1880–1936)
