Famous quotes containing the word nature:
“The nature of language may determine what most people say, but I always speak my own meaning.”
—Mason Cooley (b. 1927)
“The poet’s, commonly, is not a logger’s path, but a woodman’s. The logger and pioneer have preceded him, like John the Baptist; eaten the wild honey, it may be, but the locusts also; banished decaying wood and the spongy mosses which feed on it, and built hearths and humanized Nature for him.”
—Henry David Thoreau (1817–1862)
