Famous quotes containing the words virtual, dos and/or machine:

    Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.
    Jean Baudrillard (b. 1929)

    A curious thing about atrocity stories is that they mirror, instead of the events they purport to describe, the extent of the hatred of the people that tell them.
    Still, you can’t listen unmoved to tales of misery and murder.
    —John Dos Passos (1896–1970)

    The chrysanthemums’ astringent fragrance comes
    Each year to disguise the clanking mechanism
    Of machine within machine within machine.
    Wallace Stevens (1879–1955)
