Famous quotes containing the words sky and/or survey:
“And there is nothing in the eye,
Shut shutter of the mineral man
Who takes the fatherless dark to bed,
The acid sky to the brain-pan;
And calls the crows to peck his head.”
—Allen Tate (1899–1979)
“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)
