Famous quotes containing the words sky and/or survey:
“The soul can split the sky in two,
And let the face of God shine through.”
—Edna St. Vincent Millay (1892–1950)
“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)
