"ANAN: 'There can be no peace. Don't you see? We're a killer species. It's instinctive.'

"KIRK: 'But the instinct can be fought. We're human beings with the blood of a million savage years on our hands, but we can stop it. We can admit that we're killers, but we're not going to kill today. That's all it takes. Knowing that we won't kill today.' "
