Famous quotes containing the words swimming, pool and/or test:
“Loosed betwixt eye and lid, the swimming beams
Of memory, blind school of cuttlefish,
Rise to the air, plunge to the cold streams....”
—Allen Tate (1899–1979)
“A pool is, for many of us in the West, a symbol not of affluence but of order, of control over the uncontrollable. A pool is water, made available and useful, and is, as such, infinitely soothing to the western eye.”
—Joan Didion (b. 1934)
“Utopias are presented for our inspection as a critique of the human state. If they are to be treated as anything but trivial exercises of the imagination. I suggest there is a simple test we can apply.... We must forget the whole paraphernalia of social description, demonstration, expostulation, approbation, condemnation. We have to say to ourselves, “How would I myself live in this proposed society? How long would it be before I went stark staring mad?””
—William Golding (b. 1911)
