- David Mills: Wait, I thought all you did was kill innocent people.
- John Doe: Innocent? Is that supposed to be funny? An obese man... a disgusting man who could barely stand up; a man who if you saw him on the street, you'd point him out to your friends so that they could join you in mocking him; a man, who if you saw him while you were eating, you wouldn't be able to finish your meal. After him, I picked the lawyer and I know you both must have been secretly thanking me for that one. This is a man who dedicated his life to making money by lying with every breath that he could muster to keeping murderers and rapists on the streets!
- David Mills: Murderers?
- John Doe: A woman...
- David Mills: Murderers, John, like yourself?
- John Doe: [interrupts] A woman... so ugly on the inside she couldn't bear to go on living if she couldn't be beautiful on the outside. A drug dealer, a drug dealing pederast, actually! And let's not forget the disease-spreading whore! Only in a world this shitty could you even try to say these were innocent people and keep a straight face. But that's the point. We see a deadly sin on every street corner, in every home, and we tolerate it. We tolerate it because it's common, it's trivial. We tolerate it morning, noon, and night. Well, not anymore. I'm setting the example. What I've done is going to be puzzled over and studied and followed... forever.

- William Somerset: Ernest Hemingway once wrote, "The world is a fine place and worth fighting for." I agree with the second part.
- John Doe: Wanting people to listen, you can't just tap them on the shoulder anymore. You have to hit them with a sledgehammer, and then you'll notice you've got their strict attention.
- William Somerset: If we catch John Doe and he turns out to be the devil, I mean if he's Satan himself, that might live up to our expectations, but he's not the devil. He's just a man.
- William Somerset: This guy's methodical, exacting, and worst of all, patient.
- David Mills: He's a nut-bag! Just because the fucker's got a library card doesn't make him Yoda!
- John Doe: [about Tracy to Mills] She begged for her life...
- William Somerset: Shut up!
- John Doe: She begged for her life and...
- William Somerset: Shut up!
- John Doe: She begged for her life, and the life of the baby inside her.
- William Somerset: [backhanding Doe] Shut up!
- [Mills freezes in grieved disbelief, and Doe notices]
- John Doe: [to Somerset] Oh...! He didn't know.
- David Mills: I've been trying to figure something in my head, and maybe you can help me out, yeah? When a person is insane, as you clearly are, do you know that you're insane? Maybe you're just sitting around, reading "Guns and Ammo", masturbating in your own feces, do you just stop and go, "Wow! It is amazing how fucking crazy I really am!"? Yeah. Do you guys do that?
- William Somerset: I just don't think I can continue to live in a place that embraces and nurtures apathy as if it was virtue.
- David Mills: You're no different. You're no better.
- William Somerset: I didn't say I was different or better. I'm not. Hell, I sympathize; I sympathize completely. Apathy is the solution. I mean, it's easier to lose yourself in drugs than it is to cope with life. It's easier to steal what you want than it is to earn it. It's easier to beat a child than it is to raise it. Hell, love costs: it takes effort and work.
- William Somerset: [Reading from one of John Doe's journals] On the subway today, a man came up to me to start a conversation. He made small talk, a lonely man talking about the weather and other things. I tried to be pleasant and accommodating, but my head hurt from his banality. I almost didn't notice it had happened, but I suddenly threw up all over him. He was not pleased, and I couldn't stop laughing.
- [William Somerset looks at an object in the road]
- David Mills: What do you got?
- William Somerset: Dead dog.
- John Doe: I didn't do that.
- John Doe: I visited your home this morning after you'd left. I tried to play husband. I tried to taste the life of a simple man. It didn't work out, so I took a souvenir... her pretty head.
- David Mills: I don't think you're quitting because you believe these things you say. I don't. I think you want to believe them, because you're quitting. And you want me to agree with you, and you want me to say, "Yeah, yeah, yeah. You're right. It's all fucked up. It's a fucking mess. We should all go live in a fucking log cabin." But I won't. I won't say that. I don't agree with you. I do not. I can't.
- David Mills: C'mon, he's insane. Look. Right now he's probably dancing around in his grandma's panties, yeah, rubbing himself in peanut butter.
- David Mills: Yeah, a landlord's dream: a paralyzed tenant with no tongue.
- William Somerset: Who pays the rent on time.
- Police Captain: [answering phone that interrupted his conversation] This is not even my desk!
- [hangs up]
- John Doe: Realize detective, the only reason that I'm here right now is that I wanted to be.
- David Mills: No, no, we would have got you eventually.
- John Doe: Oh really? So, what were you doing? Biding your time? Toying with me? Allowing five innocent people to die until you felt like springing your trap? Tell me, what was the indisputable evidence you were going to use on me right before I walked up to you and put my hands in the air?
- William Somerset: [discovering what's inside the package] California, tell your people to stay away. Stay away now, don't - don't come in here. Whatever you hear, stay away! John Doe has the upper hand!
- David Mills: Has he tried to speak or communicate in any way?
- Dr. Beardsley: Even if his brain were not mush, which it is, he chewed off his own tongue long ago.
- William Somerset: Uh... Doc, is there absolutely no chance that he might survive?
- Dr. Beardsley: Detective, he'd die of shock right now if you were to shine a flashlight in his eyes. He's experienced about as much pain and suffering as anyone I've encountered, give or take... and he still has hell to look forward to. Good night.
- William Somerset: If John Doe's head splits open and a UFO should fly out, I want you to have expected it.
- John Doe: What sick ridiculous puppets we are / and what gross little stage we dance on / What fun we have dancing and fucking / Not a care in the world / Not knowing that we are nothing / We are not what was intended.
- John Doe: Nothing wrong with a man taking pleasure in his work. I won't deny my own personal desire to turn each sin against the sinner.
- Photographer: I got your picture, man, I got your picture!
- David Mills: Oh yeah? Detective Mills, M-I-L-L-S, fuck off!
- William Somerset: We'll just talk to him.
- David Mills: Uh huh. Yeah. Excuse me, sir. Are you, by any chance, a serial killer? Okay.
- William Somerset: You do the talking. Put that silver tongue of yours to work.
- David Mills: Have you been talking to my wife?
- William Somerset: Did the kid see it?
- Detective Taylor: What?
- William Somerset: The kid.
- Detective Taylor: What the fuck sort of question is that? You know, we're all going to be really glad when we get rid of you, Somerset. It's always these questions with you. "Did the kid see it?" Who gives a fuck? He's dead, his wife killed him. Anything else has nothing to do with us.
- [picks up the phone]
- David Mills: Hello?
- John Doe: I admire you. I don't know how you found me, but imagine my surprise. I respect you law enforcement agents more everyday.
- David Mills: Well, I appreciate that... John. I tell you...
- John Doe: No, no, you listen, all right? I'll be readjusting my schedule in light of today's little... setback. I just had to call and express my admiration. Sorry I had to hurt... one of you, but I really didn't have a choice, did I?
- David Mills: Hmm.
- John Doe: You will accept my apology, won't you? I feel like saying more, but I don't want to ruin the surprise.
- [hangs up]
- William Somerset: Gentlemen, gentlemen... I'll never understand. All these books, a world of knowledge at your fingertips. What do you do? You play poker all night.
- Library Guard: Hey! We've got culture! We've got culture comin' out our ass!
- George, Library Night Guard: [turns on classical music] How's this for culture?
- William Somerset: [to Tracy] Anyone who spends a significant amount of time with me finds me disagreeable. Just ask your husband.
- David Mills: Very true. Very, very true.
- William Somerset: But you gotta be a, a hero. You want to be a champion. Well, let me tell you. People don't want a champion. They want to eat cheeseburgers, play the lotto and watch television.
- William Somerset: [after finding out that Detective Mills's apartment is close to the railway tracks] Just a soothing, relaxing, vibrating home huh?
- [chuckles to himself]
- William Somerset: [recovers] I'm sorry.
- [laughs hysterically, Tracy joins in]
- David Mills: [Banging a book in frustration] Fuckin' Dante... poetry-writing faggot! Piece of shit, motherfucker!
- Officer Davis: Nothing's been touched. Everything's like I found it.
- William Somerset: What time was death established?
- Officer Davis: Like I said, I didn't touch anything... but he's had his face in a plate of spaghetti for about forty-five minutes now.
- David Mills: Wait a minute, no one bothers with vital signs?
- Officer Davis: Did I stutter? This guy ain't breathing, unless he's breathing spaghetti sauce.
- David Mills: So that's how it's done around here.
- Officer Davis: I beg your pardon, Detective, but this guy's been sitting in pile in his own piss and shit. If he wasn't dead, he would have stood up by now.
- David Mills: Do you like what you do for a living? These things you see?
- Man in Massage Parlour Booth: No, I don't. But that's life.
- [first lines]
- Detective Taylor: Neighbors heard them screaming at each other, like for two hours, and it was nothing new. Then they heard the gun go off, both barrels. Crime of passion.
- William Somerset: Yeah, just look at all the passion on that wall.
- David Mills: Who knows. So many freaks out there doin' their little evil deeds they don't wanna do... "The voices made me do it. My dog made me do it. Jodie Foster told me to do it."
- John Doe: Don't ask me to pity those people. I don't mourn them any more than I do the thousands that died at Sodom and Gomorrah.
- William Somerset: Is that to say, John, that what you were doing was God's good work?
- John Doe: The Lord works in mysterious ways.
