Famous quotes containing the word symptoms:
“For anyone addicted to reading commonplace books ... finding a good new one is much like enduring a familiar recurrence of malaria, with fever, fits of shaking, strange dreams. Unlike a truly paludismic ordeal, however, the symptoms felt while savoring a collection of one man’s pet quotations are voluptuously enjoyable ...”
—M.F.K. Fisher (1908–1992)
“Not being a K.N. [Know-Nothing] I am left as a sort of waif on the political sea with symptoms of a mild sort towards Black Republicanism.”
—Rutherford Birchard Hayes (1822–1893)
“Social movements are at once the symptoms and the instruments of progress. Ignore them and statesmanship is irrelevant; fail to use them and it is weak.”
