Famous quotes containing the words field and/or theory:

    “But the old world was restored and we returned
    To the dreary field and workshop, and the immemorial feud

    Of rich and poor. Our victory was our defeat.”
    —Sir Herbert Read (1893–1968)

    “every subjective phenomenon is essentially connected with a single point of view, and it seems inevitable that an objective, physical theory will abandon that point of view.”
