Biological

Famous quotes containing the word biological:

    When human beings have been fascinated by the contemplation of their own hearts, the more intricate biological pattern of the female has become a model for the artist, the mystic, and the saint. When mankind turns instead to what can be done, altered, built, invented, in the outer world, all natural properties of men, animals, or metals become handicaps to be altered rather than clues to be followed.
    Margaret Mead (1901–1978)

    Although there is no universal agreement as to a definition of life, its biological manifestations are generally considered to be organization, metabolism, growth, irritability, adaptation, and reproduction.
    The Columbia Encyclopedia, Fifth Edition, the first sentence of the article on “life” (based on wording in the First Edition, 1935)

    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)
