Famous quotes containing the words list of, list, synthetic and/or elements:

    The advice of their elders to young men is very apt to be as unreal as a list of the hundred best books.
    Oliver Wendell Holmes, Jr. (1841–1935)

    I am opposed to writing about the private lives of living authors and psychoanalyzing them while they are alive. Criticism is getting all mixed up with a combination of the Junior F.B.I.- men, discards from Freud and Jung and a sort of Columnist peep- hole and missing laundry list school.... Every young English professor sees gold in them dirty sheets now. Imagine what they can do with the soiled sheets of four legal beds by the same writer and you can see why their tongues are slavering.
    Ernest Hemingway (1899–1961)

    In every philosophical school, three thinkers succeed one another in the following way: the first produces out of himself the sap and seed, the second draws it out into threads and spins a synthetic web, and the third waits in this web for the sacrificial victims that are caught in it—and tries to live off philosophy.
    Friedrich Nietzsche (1844–1900)

    Nature confounds her summer distinctions at this season. The heavens seem to be nearer the earth. The elements are less reserved and distinct. Water turns to ice, rain to snow. The day is but a Scandinavian night. The winter is an arctic summer.
    Henry David Thoreau (1817–1862)
