Equilibrium (2002)
"I'm sorry."
"No you're not. You don't even know the meaning. It's just a vestigial word for you."
Sean Bean's character is reading a poetry book by W. B. Yeats when he is killed.
"But I, being poor, have only my dreams; I have spread my dreams under your feet; Tread softly because you tread on my dreams."
Mary: Let me ask you something.
[Grabs his hand]
Mary: Why are you alive?
John Preston: [Breaks free] I'm alive... I live... to safeguard the continuity of this great society. To serve Libria.
Mary: It's circular. You exist to continue your existence. What's the point?
John Preston: What's the point of your existence?
Mary: To feel. 'Cause you've never done it, you can never know it. But it's as vital as breath. And without it, without love, without anger, without sorrow, breath is just a clock... ticking.
