Famous quotes containing the words large and/or systems:
“In most nineteenth-century cities, both large and small, more than 50 percent—and often up to 75 percent—of the residents in any given year were no longer there ten years later. People born in the twentieth century are much more likely to live near their birthplace than were people born in the nineteenth century.”
—Stephanie Coontz (20th century)
“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)
