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)
“From whichever angle one looks at it, the application of racial theories remains a striking proof of the lowered demands of public opinion upon the purity of critical judgment.”
—Johan Huizinga (1872–1945)
“I grow savager and savager every day, as if fed on raw meat, and my tameness is only the repose of untamableness. I dream of looking abroad summer and winter, with free gaze, from some mountain-side,... to be nature looking into nature with such easy sympathy as the blue-eyed grass in the meadow looks in the face of the sky. From some such recess I would put forth sublime thoughts daily, as the plant puts forth leaves.”
—Henry David Thoreau (1817–1862)
“If our entertainment culture seems debased and unsatisfying, the hope is that our children will create something of greater worth. But it is as if we expect them to create out of nothing, like God, for the encouragement of creativity is in the popular mind, opposed to instruction. There is little sense that creativity must grow out of tradition, even when it is critical of that tradition, and children are scarcely being given the materials on which their creativity could work”
—C. John Sommerville (20th century)
