Famous quotes containing the words arc, cascade and/or volcanic:

    Male urination really is a kind of accomplishment, an arc of transcendance. A woman merely waters the ground she stands on.
    Camille Paglia (b. 1947)

    “End of tomorrow.
    Don’t try to start the car or look deeper
    Into the eternal wimpling of the sky: luster
    On luster, transparency floated onto the topmost layer
    Until the whole thing overflows like a silver
    Wedding cake or Christmas tree, in a cascade of tears.”
    John Ashbery (b. 1927)

    Each of us, even the lowliest and most insignificant among us, was uprooted from his innermost existence by the almost constant volcanic upheavals visited upon our European soil and, as one of countless human beings, I can’t claim any special place for myself except that, as an Austrian, a Jew, writer, humanist and pacifist, I have always been precisely in those places where the effects of the thrusts were most violent.
    Stefan Zweig (18811942)
