Famous quotes containing the words order and/or theory:
“If our condition were truly happy, we would not need diversion from thinking of it in order to make ourselves happy.”
—Blaise Pascal (1623–1662)
“A theory of the middle class: that it is not to be determined by its financial situation but rather by its relation to government. That is, one could shade down from an actual ruling or governing class to a class hopelessly out of relation to government, thinking of gov’t as beyond its control, of itself as wholly controlled by gov’t. Somewhere in between and in gradations is the group that has the sense that gov’t exists for it, and shapes its consciousness accordingly.”
—Lionel Trilling (1905–1975)
