Dr. Zaius: Ah, yes - the young ape with a shovel. I hear you're planning another archeological expedition. Cornelius, a friendly word of warning - as you dig for artifacts, be sure you don't bury your reputation.

Dr. Zaius: Dr. Zira, I must caution you. Experimental brain surgery on these creatures is one thing, and I'm all in favor of it. But your behavior studies are another matter. To suggest that we can learn anything about the simian nature from a study of man is sheer nonsense. Why, man is a nuisance. He eats up his food supply in the forest, then migrates to our green belts and ravages our crops. The sooner he is exterminated, the better. It's a question of simian survival.

Dr. Zaius: Have you forgotten your scripture, the thirteenth scroll? "And Proteus brought the upright beast into the garden and chained him to a tree and the children did make sport of him."

Dr. Zaius: The Forbidden Zone was once a paradise. Your breed made a desert of it, ages ago.

Dr. Zaius: You are a menace. A walking pestilence.

Dr. Zaius: You are right, I have always known about man. From the evidence, I believe his wisdom must walk hand and hand with his idiocy. His emotions must rule his brain. He must be a warlike creature who gives battle to everything around him, even himself.

Cornelius: [reading from the sacred scrolls of the apes]
Beware the beast Man, for he is the Devil's pawn. Alone among God's primates, he kills for sport or lust or greed. Yea, he will murder his brother to possess his brother's land. Let him not breed in great numbers, for he will make a desert of his home and yours. Shun him; drive him back into his jungle lair, for he is the harbinger of death.
