Famous quotes containing the word involuntary:

    Like everything which is not the involuntary result of fleeting emotion but the creation of time and will, any marriage, happy or unhappy, is infinitely more interesting than any romance, however passionate.
    —W.H. (Wystan Hugh)

    We are things of dry hours and the involuntary plan,
    Grayed in, and gray. “Dream” makes a giddy sound, not strong
    Like “rent,” “feeding a wife,” “satisfying a man.”
    Gwendolyn Brooks (b. 1917)

    It is clear that all verbal structures with meaning are verbal imitations of that elusive psychological and physiological process known as thought, a process stumbling through emotional entanglements, sudden irrational convictions, involuntary gleams of insight, rationalized prejudices, and blocks of panic and inertia, finally to reach a completely incommunicable intuition.
    Northrop Frye (b. 1912)
