Famous quotes containing the words symmetry and/or flavor:

    “What makes a regiment of soldiers a more noble object of view than the same mass of mob? Their arms, their dresses, their banners, and the art and artificial symmetry of their position and movements.”
    —George Gordon Noel Byron (1788–1824)

    “No man ever quite believes in any other man. One may believe in an idea absolutely, but not in a man. In the highest confidence there is always a flavor of doubt—a feeling, half instinctive and half logical, that, after all, the scoundrel may have something up his sleeve.”
    —H.L. (Henry Lewis)
