Famous quotes containing the word nature:
“For, as it is dislocation and detachment from the life of God, that makes things ugly, the poet, who re-attaches things to nature and the Whole,—re-attaching even artificial things, and violations of nature, to nature, by a deeper insight,—disposes very easily of the most disagreeable facts.”
—Ralph Waldo Emerson (1803–1882)
“Because it is in the nature of things that they become extreme, we have passed down from manliness to cruelty. If I had been told when I was 20 that there was a tavern in the town where the brave and the cruel were gathered together, I would have run all the way and I would have gone up to the largest and leatheriest of the denizens and said: “If you truly love me, kill the bartender.””
—Quentin Crisp (b. 1908)
