Famous quotes containing the word nature:
“But man postpones or remembers; he does not live in the present, but with reverted eye laments to the past, or, heedless of the riches that surround him, stands on tiptoe to foresee the future. He cannot be happy and strong until he too lives with nature in the present, above time.”
—Ralph Waldo Emerson (1803–1882)
“America is still mostly xenophobic and racist. That’s the nature of America, I think.”
—Jerry Garcia (1942–1995)
