Famous quotes containing the words domain and/or wall:

    When it had long since outgrown his purely medical implications and become a world movement which penetrated into every field of science and every domain of the intellect: literature, the history of art, religion and prehistory; mythology, folklore, pedagogy, and what not.

    cut so small in the wall where
    the vision which echoes loneliness
    brings a scent of wild flowers in the wood.
