“That’s what human relationships are about – selective sharing and hiding of information to the point of crazy confusion.”

Context: The compartment was getting crowded as other Pyrrans pushed in. Kerk, almost to the door, turned back to face Jason.
"I'll tell you what's wrong with armistice," he said. "It's a coward's way out, that's what it is. It's all right for you to suggest it, you're from off-world and don't know any better. But do you honestly think I could entertain such a defeatist notion for one instant? When I speak, I speak not only for myself, but for all of us here. We don't mind fighting, and we know how to do it. We know that if this war was over we could build a better world here. At the same time, if we have the choice of continued war or a cowardly peace — we vote for war. This war will only be over when the enemy is utterly destroyed!"
The listening Pyrrans murmured in agreement, and Jason had to shout to be heard above them. "That's really wonderful. I bet you even think it's original. But don't you hear all that cheering offstage? Those are the spirits of every saber-rattling sonofabitch that ever plugged for noble war. They even recognize the old slogan. We're on the side of light, and the enemy is a creature of darkness. And it doesn't matter a damn if the other side is saying the same thing. You've still got the same old words that have been killing people since the birth of the human race. A 'cowardly peace,' that's a good one. Peace means not being at war, not fighting. How can you have a cowardly not-fighting. What are you trying to hide with this semantic confusion? Your real reasons? I can't blame you for being ashamed of them — I would be. Why don't you just come out and say you are keeping the war going because you enjoy killing? Seeing things die makes you and your murderers happy, and you want to make them happier still!"
