Khan Noonien Singh: You are an excellent tactician, Captain. You let your second-in-command attack while you sit and watch for weakness.
Captain James T. Kirk: You have a tendency to express ideas in military terms, Mr. Khan.
Captain James T. Kirk: This is a social occasion.
Khan Noonien Singh: [laughs] It has been said that, uh, "social occasions" are only warfare concealed. Many prefer it more honest, more... open.
Captain James T. Kirk: You fled. Why? Were you afraid?
Khan Noonien Singh: I've never been afraid.
Captain James T. Kirk: But you left at the very time mankind needed courage.
Khan Noonien Singh: [angrily] We offered the world ORDER!
Khan Noonien Singh: [smiles admiringly, realizing he's revealed more than he would wish] Excellent. Excellent.
Dr. McCoy: [lying in sickbay, Khan surprises McCoy and holds a knife to his throat, then pauses] Well, either choke me or cut my throat. Make up your mind.
Khan Noonien Singh: English... I thought I dreamed hearing it. Where am I?
Dr. McCoy: You're in...
[Khan tightens his grip. McCoy continues in a lower voice]
Dr. McCoy: You're in bed, holding a knife at your doctor's throat.
Khan Noonien Singh: Answer my question.
Dr. McCoy: It would be most effective if you would cut the carotid artery, just under the left ear.
Captain James T. Kirk: [looking at a library picture of Khan on viewscreen] Name: Khan Noonien Singh.
Mr. Spock: From 1992 through 1996, absolute ruler of more than a quarter of your world, from Asia through the Middle East.
Dr. McCoy: The last of the tyrants to be overthrown.
Scott: I must confess, gentlemen. I've always held a sneaking admiration for this one.
Captain James T. Kirk: He was the best of the tyrants and the most dangerous. They were supermen in a sense. Stronger, braver, certainly more ambitious, more daring.
Mr. Spock: Gentlemen, this romanticism about a ruthless dictator is...
Captain James T. Kirk: Mr. Spock, we humans have a streak of barbarism in us. Appalling, but there, nevertheless.
Scott: There were no massacres under is rule.
Mr. Spock: And as little freedom.
Dr. McCoy: No wars until he was attacked.
Mr. Spock: Gentlemen...
[All but Spock laugh]
Captain James T. Kirk: Mr. Spock, you misunderstand us. We can be against him and admire him all at the same time.
Mr. Spock: Illogical.
Captain James T. Kirk: Totally.
Khan Noonien Singh: Nothing ever changes, except man. Your technical accomplishments? Improve a mechanical device and you may double productivity, but improve man and you gain a thousandfold. I am such a man.
Captain James T. Kirk: What's your name?
Khan Noonien Singh: Khan is my name.
Captain James T. Kirk: Just Khan? Nothing else?
Khan Noonien Singh: Khan.
Captain James T. Kirk: [offering Khan a hostile planet to inhabit] Those men went on to tame a continent, Mr. Khan. Can you tame a world?
Khan Noonien Singh: Have you ever read Milton, Captain?
Captain James T. Kirk: Yes. I understand.
Khan Noonien Singh: [to Joaquin] It does not matter. The Captain is dead. Take Mr. Spock next.
Dr. McCoy: A pity you wasted your life on command, Jim. You'd have made a fair psychologist.
Captain James T. Kirk: [in mock arrogance] Fair?
Mr. Spock: I fail to understand why it always gives you pleasure to see me proven wrong.
Captain James T. Kirk: An emotional Earth weakness of mine.
Captain James T. Kirk: [about to beam aboard the Botany Bay] You ready, Bones?
Dr. McCoy: No. I signed aboard this ship to practice medicine, not to have my atoms scattered back and forth across space by this gadget.
Captain James T. Kirk: You're an old-fashioned boy, McCoy.
Captain James T. Kirk: You suspect some danger?
Mr. Spock: Insufficient facts always invites danger, Captain.
Captain James T. Kirk: Well, I'd better get some facts.
Khan Noonien Singh: [to Marla] I am honored. Thank you. But I caution you: such men dare take what they want.
Lt. Marla McGivers: I don't know if you're going to like living in our time.
Khan Noonien Singh: Then I'm going to have to remould it to my liking.
Lt. Marla McGivers: [Khan moves in to embrace Marla] Please don't.
Khan Noonien Singh: Go.
[pushes her away]
Khan Noonien Singh: Or stay, but do it because it is what you WISH to do!
Khan Noonien Singh: Well?
Lt. Marla McGivers: I'll stay a little longer.
Khan Noonien Singh: How many minutes do you graciously offer?
Lt. Marla McGivers: I only meant...
Khan Noonien Singh: This grows tiresome. You must now ASK to stay.
Lt. Marla McGivers: [timidly] I'd like to stay... please.
Khan Noonien Singh: Joaquin, the trip is over. The battle begins again, only this time it's not a world we win. It's a universe.
Captain James T. Kirk: [narrating] Stardate 3142.8. They have my ship, discarding their own worthless vessel. Only moments of air left on the bridge now. Commendations recommended for Lieutenant Uhura, Technicians First Class Thule and Harrison... Lieutenant Spinelli... and, of course, Mr. Spock. I take full responsibility... I take full...
Captain James T. Kirk: Care to join the landing party, Doctor?
Dr. McCoy: Well, if you're actually giving me a choice...
Captain James T. Kirk: I'm not.
Captain James T. Kirk: Lieutenant, at any one time, the safety of this entire vessel might depend on the performance of a single crewman aboard, and the fact that you find a man strangely compelling to you personally...
Lt. Marla McGivers: Not personally, Captain. Professionally. My profession is historian, and when I specimen from the past alive, I'm in the sheer delight of examining his mind.
Captain James T. Kirk: And men were more adventuresome then. Bolder, more coloful.
Lt. Marla McGivers: Yes, sir, I think they were.
Captain James T. Kirk: Good. If I can have honesty, it's easier to overlook mistakes. That's all.
Lt. Marla McGivers: Yes, sir.
Khan Noonien Singh: Captain, although your abilities intrigue me, you are quite honestly inferior. Mentally, physically. In fact, I am surprised how little improvement there has been in human evolution. Oh, there has been technical advancement, but, how little man himself has changed.
Khan Noonien Singh: Yes, it appears we will do well in your century, Captain.
[Khan is escorted out by Security]
Scott: It's a shame for a good Scotsman to admit it, but I'm not up on Milton
Captain James T. Kirk: The statement Lucifer made when he fell into the pit: "It is better to rule in Hell than serve in Heaven."
Mr. Spock: It would be interesting, Captain, to return to that world in 100 years and learn what crop had sprung from the seed you planted today.
Captain James T. Kirk: Yes, Mr. Spock. It would indeed.
