What is branch of knowledge?

Famous quotes containing the words branch of, knowledge and/or branch:

    When I am finishing a picture I hold some God-made object up to it—a rock, a flower, the branch of a tree or my hand—as a kind of final test. If the painting stands up beside a thing man cannot make, the painting is authentic. If there’s a clash between the two, it is bad art.
    Marc Chagall (1889–1985)

    Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.
    Susanne K. Langer (1895–1985)

    The optimist proclaims that we live in the best of all possible worlds; and the pessimist fears this is true.
    —James Branch Cabell (1879–1958)
