Abraham Lincoln: No need to check your voice telegraph device. Do I gather that you recognize me?
Kirk: I recognize what you appear to be.
Abraham Lincoln: And appearances can be most deceiving, but not in this case, James Kirk. I am Abraham Lincoln.
Abraham Lincoln: I have been described in many ways, Mr. Spock, but never with that word.
Scotty: I'd have expected sanity from the ship's surgeon, at least! President Lincoln, indeed! No doubt to be followed by Louis of France and Robert the Bruce.
Kirk: If so, we'll execute appropriate honors to each, Mr. Scott.
Abraham Lincoln: A most interesting way to come aboard, Captain. What was the device used?
Kirk: An energy-matter scrambler, sir. The molecules in your body are converted into energy, then beamed into this chamber and reconverted back into their original pattern.
Abraham Lincoln: Well, since I'm obviously here, and quite whole, whatever you mean apparently works very well indeed.
Abraham Lincoln: What a charming Negress. Oh, forgive me, my dear. I know in my time some used that term as a description of property.
Uhura: But why should I object to that term, sir? In our century, we've learned not to fear words.
McCoy: Where the devil are they?
Scotty: Probably looking up haggis in the galley. They've been everywhere else.
McCoy: Jim, I would be the last to advise you on your command image...
Kirk: I doubt that, Bones, but continue.
Scotty: Lincoln died three centuries ago hundreds of light-years away.
Spock: (pointing helpfully a different way) More that direction, Engineer.
McCoy: You're both out of your heads!
Scotty: Aye, sir.
Kirk: And you're on the edge of insubordination!
McCoy: Would I be on the edge of insubordination to remind the captain this smells of something happening to him that I might not be able to patch together again?
Surak: Live long and prosper, Spock. May you also, Captain Kirk.
Spock: It is not logical that you are Surak. There is no fact, extrapolation of fact or theory which would make possible...
Surak: Whatever I am, would it harm you to give response?
Spock: Live long and prosper, image of Surak, father of all we now hold true.
Surak: The, uh, "image of Surak" read in your face what is in your mind, Spock.
Spock: As I turned and my eyes beheld you, I displayed emotion. I beg forgiveness.
Surak: The cause was more than sufficient. Let us speak no further of it. In my time, we knew not of Earth men. I am pleased to see that we have differences. May we together become greater than the sum of both of us.
Yarnek: We ask you to observe with us the confrontation of the two opposing philosophies you term good and evil. Since this is our first experiment with Earthlings, our theme is a simple one. Survival, life and death. Your philosophies are alien to us, and we wish to understand them and discover which is the stronger. We learn by observing such spectacles.
Kirk: What do you mean, "survival"?
Yarnek: The word is explicit. If you and Spock survive, you return to your vessel. If you do not, your existence is ended.
Kirk: Anyone hurt?
Abraham Lincoln: I fear my clothing is somewhat damaged, but how delightful to discover at my age that I can still wrestle.
Abraham Lincoln: For an illusion, my opponent carried a considerable punch. Oh, I forgot. You consider me an illusion too.
Abraham Lincoln: Mmm. Do you drink whiskey?
Kirk: Occasionally. Why?
Abraham Lincoln: Because you have qualities very much like those of another man admire greatly--General Grant.
Spock: Logic dictates that we consider another course.
Kirk: We don't have much time, Spock.
Surak: In my time on Vulcan, we also faced these same alternatives. We'd suffered devastating wars which nearly destroyed our planet. Another was about to begin. We were torn. But out of our suffering some of us found the discipline to act. We sent emissaries to our opponents to propose peace. The first were killed, but others followed. Ultimately, we achieved peace, which has lasted since then.
Kirk: Circumstances were different then, Surak.
Surak: The face of war has never changed, Captain. Surely it is more logical to heal than kill.
Kirk: I'm afraid that kind of logic doesn't apply here.
Surak: That is precisely why we should not fight.
Kirk: Your Surak is a brave man.
Spock: Men of peace usually are, Captain. On Vulcan, he is revered as the father of our civilization. The father image holds much meaning for us.
Kirk: You show emotion, Spock?
Spock: I deeply respect what he has accomplished.
Abraham Lincoln: James. Remember, I was something of a backwoodsman. I doubt that you could do what I was bred to.
Abraham Lincoln: One matter further, gentlemen. We fight on their level. With trickery, brutality, finality. We match their evil. I know, James. I was reputed to be a gentle man. But I was commander in chief during the four bloodiest years of my country's history. I gave orders that sent a hundred thousand men to their death at the hands of their brothers. There is no honorable way to kill, no gentle way to destroy. There is nothing good in war except its ending. And you are fighting for the lives of your crew.
Kirk: Your campaign, Mr. President.
Kirk: How many others have you done this to? What gives you the right to hand out life and death?
Yarnek: The same right that brought you here--the need to know new things.
Kirk: We came in peace.
Yarnek: And you may go in peace.
