Famous quotes containing the words ground and/or support:
“All I’m telling you is that that little creature in there has as much right to live as you do. Don’t forget, you invaded his world. You sank a pipe six miles into the ground and when he climbed up you set dogs on him, shot him.”
—Richard Fielding, and Lee Sholem. Superman (George Reeves)
“There are so many intellectual and moral angels battling for rationalism, good citizenship, and pure spirituality; so many and such eminent ones, so very vocal and authoritative! The poor devil in man needs all the support and advocacy he can get. The artist is his natural champion. When an artist deserts to the side of the angels, it is the most odious of treasons.”
—Aldous Huxley (1894–1963)
