Famous quotes containing the words superior and/or aperture:
“The State never intentionally confronts a man’s sense, intellectual or moral, but only his body, his senses. It is not armed with superior wit or honesty, but with superior physical strength.”
—Henry David Thoreau (1817–1862)
“Animals used to provide a lowlife way to kill and get away with it, as they do still, but, more intriguingly, for some people they are an aperture through which wounds drain. The scapegoat of olden times, driven off for the bystanders’ sins, has become a tender thing, a running injury. There, running away ... is me: hurt it and you are hurting me.”
—Edward Hoagland (b. 1932)
