Famous quotes containing the word effect:

    To see distinctly the machinery—the wheels and pinions—of any work of Art is, unquestionably, of itself, a pleasure, but one which we are able to enjoy only just in proportion as we do not enjoy the legitimate effect designed by the artist.
    Edgar Allan Poe (1809–1849)
