Famous quotes containing the words exact, timing and/or years:

    Neither Aristotelian nor Russellian rules give the exact logic of any expression of ordinary language; for ordinary language has no exact logic.
    Sir Peter Frederick Strawson (b. 1919)

    A great man always considers the timing before he acts.
    Chinese proverb.

    Uncle Matthew’s four years in France and Italy between 1914 and 1918 had given him no great opinion of foreigners. “Frogs,” he would say, “are slightly better than Huns or Wops, but abroad is unutterably bloody and foreigners are fiends.”
    Nancy Mitford (1904–1973)
