Mirror Spock quotes from Star Trek: The Original Series

Spock

Why, thank you, [Doctor / Captain].

Spock

Fascinating.

Spock

Interesting.

Uhura

Mr. Spock, sometimes I think if I hear that word "frequency" again, I'll cry.

Spock

It is illogical for a communications officer to resent the word "frequency."

Uhura

Then I'm an illogical woman. Why don't you tell me what an attractive lady I am? Or how your planet looks when the moon is full.

Spock

Vulcan has no moon, Miss Uhura.

Uhura

I'm not surprised.

Spock

Check.

Kirk

Checkmate.

Spock

Your illogical approach to chess does have its advantages on occasion, Captain.

Kirk

I'd prefer to call it inspired.

Spock

As you wish.

Kirk

Mr. Spock?

Spock

[unemotionally] My legs. They're broken.

Kirk

Let him go too, Charlie.

Charlie

Why?

Kirk

Because I'm telling you to. You need me to run this ship and I need him.

Kirk

Have I ever mentioned you play a very irritating game of chess, Mr. Spock?

Spock

Irritating? [smiling] Ah, yes. One of your Earth emotions.

Kirk

Certain you don't know what irritation is?

Spock

The fact one of my ancestors married a human female...

Kirk

Terrible having bad blood like that.

Kirk

What makes you so right and a trained psychiatrist wrong?

Spock

Because she feels. I don't. All I know is logic.

Kirk

He didn't ask for what happened to him.

Spock

I felt for him, too.

Kirk

I believe there's some hope for you after all, Mr. Spock.

Spock

Our spectro-readings showed no contamination, no unusual elements present.

Scotty

At least none your tricorders could register.

Spock

Instruments register only those things they're designed to register. Space still contains infinite unknowns.

McCoy

We're doing everything that's possible!

Kirk

Bones, I want the impossible checked out too!

Spock

We have here an unusual opportunity to appraise the human mind, or to examine, in Earth terms, the roles of good and evil in a man-- his negative side, which you call hostility, lust, violence, and his positive side, which Earth people express as compassion, love, tenderness.

McCoy

Are you aware it's the captain's guts you're analyzing?

Spock

Yes, and what makes one man an exceptional leader? We see indications that it's his negative side which makes him strong, that his evil side, controlled and disciplined, is vital to his strength. Your negative side removed from you, the power of command begins to elude you.

McCoy

Jim, you can't risk your life on a theory!

Spock

Being split in two halves is no theory with me, Doctor. I have a human half, you see, as well as an alien half, submerged, constantly at war with each other. Personal experience, Doctor. I survive it because my intelligence wins out over both, makes them live together. Your intelligence would enable you to survive as well.

Spock

The older the victim, the more rapid the progress of the disease.

Kirk

And you? The disease doesn't seem to be interested.

Spock

I am a carrier. Whatever happens, I can't go back to the ship. And I do want to go back to the ship, Captain.

Kirk

Of course, Mr. Spock.

Spock

Interesting. You Earth people glorify organized violence for forty centuries, but you imprison those who employ it privately.

McCoy

And, of course, your people found an answer.

Spock

We disposed of emotion, Doctor. Where there's no emotion, there's no motive for violence.

Spock

Has it occurred to you that there's a certain... inefficiency in constantly questioning me on things you've already made up your mind about?

Kirk

It gives me emotional security.
