Famous quotes containing the words domain and/or wall:

    “Without metaphor the handling of general concepts such as culture and civilization becomes impossible, and that of disease and disorder is the obvious one for the case in point. Is not crisis itself a concept we owe to Hippocrates? In the social and cultural domain no metaphor is more apt than the pathological one.”
    —Johan Huizinga (1872–1945)

    “I discovered
    the colors in the wall that woke
    when spray from the hose
    played on its pocks and warts....”
    —Denise Levertov (b. 1923)
