Famous quotes containing the words biological and/or role:

    “No poetic phantasy
    but a biological reality,
    a fact: I am an entity
    like bird, insect, plant
    or sea-plant cell;
    I live; I am alive.”
    —Hilda Doolittle (1886–1961)

    “Such is the role of poetry. It unveils, in the strict sense of the word. It lays bare, under a light which shakes off torpor, the surprising things which surround us and which our senses record mechanically.”
    —Jean Cocteau (1889–1963)
