Famous quotes containing the words angle, repose and/or materials:
“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 (16851753)
“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 (18791955)
“He was no specialist except in the relation of things.... He took most of his materials at second hand.... But no matter who mined the gold, the image and superscription are his.”
—Woodrow Wilson (18561924)
