Famous quotes containing the words dark and/or matter:
“And the glory of character is in affronting the horrors of depravity to draw thence new nobilities of power: as Art lives and thrills in new use and combining of contrasts, and mining into the dark evermore for blacker pits of night.”
—Ralph Waldo Emerson (1803–1882)
“It is not every man who can be a Christian, even in a very moderate sense, whatever education you give him. It is a matter of constitution and temperament, after all. He may have to be born again many times. I have known many a man who pretended to be a Christian, in whom it was ridiculous, for he had no genius for it. It is not every man who can be a free man, even.”
—Henry David Thoreau (1817–1862)
