Famous quotes containing the words list and/or analysis:

    “Lovers, forget your love,
    And list to the love of these,
    She a window flower,
    And he a winter breeze.”
    —Robert Frost (1874–1963)

    “Cubism had been an analysis of the object and an attempt to put it before us in its totality; both as analysis and as synthesis, it was a criticism of appearance. Surrealism transmuted the object, and suddenly a canvas became an apparition: a new figuration, a real transfiguration.”
    —Octavio Paz (b. 1914)
