Famous quotes containing the words elements of, elements and/or phone:
“The elements of success in this business do not differ from the elements of success in any other. Competition is keen and bitter. Advertising is as large an element as in any other business, and since the usual avenues of successful exploitation are closed to the profession, the adage that the best advertisement is a pleased customer is doubly true for this business.”
—Madeleine [Blair], U.S. prostitute and madam. Madeleine, ch. 5 (1919)
“English general and singular terms, identity, quantification, and the whole bag of ontological tricks may be correlated with elements of the native language in any of various mutually incompatible ways, each compatible with all possible linguistic data, and none preferable to another save as favored by a rationalization of the native language that is simple and natural to us.”
—Willard Van Orman Quine (b. 1908)
“I went into the kitchen and got halfway to the phone before I realized that I couldnt call her.... A lot of people who lost a mother or father or husband or wife will tell you that they find themselves almost talking out loud. I do that a lot.”
—Bill Clinton (b. 1946)
