Famous quotes containing the words comparison and/or systems:
“Intolerance respecting other people’s religion is toleration itself in comparison with intolerance respecting other people’s art.”
—Wallace Stevens (1879–1955)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
