Famous quotes containing the words sky and/or survey:
“The sky breaks.
It sags and breathes upon my face.
in the presence of mine enemies, mine enemies
The world is full of enemies.
There is no safe place.”
—Anne Sexton (1928–1974)
“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)
