Famous quotes containing the words protected and/or mode:

    “U.S. international and security policy ... has as its primary goal the preservation of what we might call “the Fifth Freedom,” understood crudely but with a fair degree of accuracy as the freedom to rob, to exploit and to dominate, to undertake any course of action to ensure that existing privilege is protected and advanced.”
    —Noam Chomsky (b. 1928)

    “Literature exists at the same time in the modes of error and truth; it both betrays and obeys its own mode of being.”
    —Paul Deman (1919–1983)
