Famous quotes containing the words resonance, sphere and/or air:

    It is closing time in the gardens of the West and from now on an artist will be judged only by the resonance of his solitude or the quality of his despair.
    Cyril Connolly (1903–1974)

    It is in the nature of allegory, as opposed to symbolism, to beg the question of absolute reality. The allegorist avails himself of a formal correspondence between “ideas” and “things,” both of which he assumes as given; he need not inquire whether either sphere is “real” or whether, in the final analysis, reality consists in their interaction.
    Charles, Jr. Feidelson, U.S. educator, critic. Symbolism and American Literature, ch. 1, University of Chicago Press (1953)

    Speak the speech, I pray you, as I pronounced it to you—trippingly on the tongue; but if you mouth it, as many of your players do, I had as lief the town-crier spoke my lines. Nor do not saw the air too much with your hand, thus, but use all gently; for in the very torrent, tempest, and as I may say, the whirlwind of your passion, you must acquire and beget a temperance that may give it smoothness.
    William Shakespeare (1564–1616)
