Primary Open Angle

Famous quotes containing the words primary, open and/or angle:

    Wilful sterility is, from the standpoint of the nation, from the standpoint of the human race, the one sin for which the penalty is national death, race death; a sin for which there is no atonement....

    Theodore Roosevelt (1858–1919)

    An open foe may prove a curse,
    But a pretended friend is worse.
    John Gay (1685–1732)

    The inhabitants of earth behold commonly but the dark and shadowy under side of heaven’s pavement; it is only when seen at a favorable angle in the horizon, morning or evening, that some faint streaks of the rich lining of the clouds are revealed.
    Henry David Thoreau (1817–1862)
