Famous quotes containing the words angle of, angle, repose and/or materials:

    The good lawyer is not the man who has an eye to every side and angle of contingency, and qualifies all his qualifications, but who throws himself on your part so heartily, that he can get you out of a scrape.
    Ralph Waldo Emerson (1803–1882)

    It is a mistake, to think the same thing affects both sight and touch. If the same angle or square, which is the object of touch, be also the object of vision, what should hinder the blind man, at first sight, from knowing it?
    George Berkeley (1685–1753)

    Once it was, the repose of night,
    Was a place, strong place, in which to sleep.
    It is shaken now. It will burst into flames,
    Either now or tomorrow or the day after that.
    Wallace Stevens (1879–1955)

    If only it were God’s will that printed and written materials have as much influence on the people as the princes and their censors fear! Considering the countless good books we have, the world would have changed for the better a long time ago.
    Franz Grillparzer (1791–1872)
