Famous quotes containing the words approach and/or space:
“You should approach Joyce’s Ulysses as the illiterate Baptist preacher approaches the Old Testament: with faith.”
—William Faulkner (1897–1962)
“In bourgeois society, the French and the industrial revolution transformed the authorization of political space. The political revolution put an end to the formalized hierarchy of the ancien regimé.... Concurrently, the industrial revolution subverted the social hierarchy upon which the old political space was based. It transformed the experience of society from one of vertical hierarchy to one of horizontal class stratification.”
—Donald M. Lowe, U.S. historian, educator. History of Bourgeois Perception, ch. 4, University of Chicago Press (1982)
