“We live in a world that has walls and those walls need to be guarded by men with guns.”

“Son, we live in a world that has walls, and those walls have to be guarded by men with guns. Who's gonna do it? You? You, Lt. Weinburg? I have a greater responsibility than you could possibly fathom. You weep for Santiago, and you curse the marines. You have that luxury. You have the luxury of not knowing what I know. That Santiago's death, while tragic, probably saved lives. And my existence, while grotesque and incomprehensible to you, saves lives. You don't want the truth because deep down in places you don't talk about at parties, you want me on that wall, you need me on that wall. We use words like honor, code, loyalty. We use these words as the backbone of a life spent defending something. You use them as a punchline. I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the blanket of the very freedom that I provide, and then questions the manner in which I provide it. I would rather you just said thank you, and went on your way, otherwise, I suggest you pick up a weapon, and stand a post. Either way, I don't give a damn what you think you are entitled to.”

“We are fascinated, all of us, by the implacable otherness of others. And we wish to penetrate by hypothesis, by daydream, by scientific investigation those leaden walls that encase the human spirit, that define it and guard it and hold it forever inaccessible.”

“O, mighty, divinely delimited wisdom of walls, boundaries! I is perhaps the most magnificent of all inventions. Man ceased to be a wild animal only when he build the first wall. Men ceased to be a wild man only when we built the Green Wall, only when, by means of that wall, we isolated our perfect machine world from the irrational, ugly world of trees, birds, and animals...”

“My hero finally found me in that too-high tower, rescued me from it's cold walls, set me down among free men and bolted.Freedom, with all it's possibilities, just feels cold and lonely. I want to go back to my tower. I need those walls. I need the protection.The walls were always my true plus-one. ”

“A happy wall is a long-lived wall, a practical wall, a useful wall.”
