Dr. Rosen: Imagine if you suddenly learned that the people, the places, the moments most important to you were not gone, not dead, but worse, had never been. What kind of hell would that be?
Alicia: How big is the universe? Nash: Infinite. Alicia: How do you know? Nash: I know because all the data indicates it's infinite. Alicia: But it hasn't been proven yet. Nash: No. Alicia: You haven't seen it. Nash: No. Alicia: How do you know for s...
Hansen: So how about it, Nash? You scared? Nash: Terrified... mortified... petrified... stupefied... by you.
[from deleted scene] Nash: Perhaps it is good to have a beautiful mind, but an even greater gift is to discover a beautiful heart.
Nash: What truly is logic? Who decides reason? My quest has taken me to the physical, the metaphysical, the delusional, and back. I have made the most important discovery of my career - the most important discovery of my life. It is only in the myste...
Nash: I find you attractive. Your aggressive moves toward me... indicate that you feel the same way. But still, ritual requires that we continue with a number of platonic activities... before we have sex. I am proceeding with these activities, but in...
Nash: Can you see him? Student: Yeah. Nash: Okay. I am always suspicious of new people. Now that I know you're real, who are you, and what can I do for you?

Nash: You once said that God must be a painter because he gave us so many colors. Alicia: I didn't think you were listening... Nash: I was listening.
Nash: I've made the most important discovery of my life. It's only in the mysterious equation of love that any logic or reasons can be found. I'm only here tonight because of you. You are the only reason I am... you are all my reasons.
Nash: Alicia, does our relationship warrant long-term commitment? I need some kind of proof, some kind of verifiable, empirical data. Alicia: I'm sorry, just give me a moment to redefine my girlish notions of romance.
Nash: I've gotten used to ignoring them and I think, as a result, they've kind of given up on me. I think that's what it's like with all our dreams and our nightmares, Martin, we've got to keep feeding them for them to stay alive.
Nash: This class will be a waste of your - and what is infinitely worse - my time.
Alicia: [about the stars] I once tried to count them all. I, actually, made it to 4,348. Nash: You are exceptionally odd. Alicia: I bet you're very popular with the girls.
Nash: [to Thomas King] I still see things that are not here. I just choose not to acknowledge them. Like a diet of the mind, I just choose not to indulge certain appetites; like my appetite for patterns; perhaps my appetite to imagine and to dream.
