Famous quotes containing the words fish and/or counter:
“Everything seems beautiful because you don’t understand. Those flying fish, they’re not leaping for joy, they’re jumping in terror. Bigger fish want to eat them. That luminous water, it takes its gleam from millions of tiny dead bodies, the glitter of putrescence. There’s no beauty here, only death and decay.”
—Curtis Siodmak (1902–1988)
“The individual protests against the world, but he doesn’t get beyond protest, he is just a single protester. When he wants to be more than that, he has to counter power with power, he has to oppose the system with another system.”
—Friedrich Dürrenmatt (1921–1990)
