Famous quotes containing the words large and/or systems:
“The educational system in large countries will always be utterly mediocre, for the same reason that the cooking in large kitchens is mediocre at best.”
—Friedrich Nietzsche (1844–1900)
“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)
