Famous quotes containing the words sky and/or survey:
“Seas of bright juice suffuse heaven.
The earth by the sky staid with, the daily close of their junction,
The heav’d challenge from the east that moment over my head,
The mocking taunt, See then whether you shall be master!”
—Walt Whitman (1819–1892)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
