I am a Vulcan, doctor. Pain is a thing of the mind. The mind can be controlled.
You're only half Vulcan. What about the human half?
It is proving to be an inconvenience, but it is manageable.

I admire your curiosity Doctor, but I assure you I'm all right.
You may be controlling the pain, Mr. Spock... but you're far from all right.
[presenting the first findings on the alien creature] Interesting, gentlemen. A one-cell creature resembling, more than anything else, a huge, individual brain cell.
Yes. That would answer a lot of questions.
Do you understand what I'm suggesting, Captain?
I think so. This may be one cell in a larger organism, an incredibly huge organism, in fact.
And although it is not physically connected to the other cells, it is, nevertheless, part of the whole creature, guided by the whole, drawing its strength from the whole, which probably accounts for its unusual resistance to our phaser weapons.
[narrating] Captain's log, stardate 3289.8. I am faced with the most difficult decision of my life. Unless we find a way to destroy the creatures without killing their human hosts, my command responsibilities will force me to kill over a million people.
Mr. Spock, regaining eyesight would be an emotional experience for most. You, I presume felt nothing?
Quite the contrary, Captain, I had a very strong reaction. My first sight was the face of Dr. McCoy bending over me.
Hm, 'tis a pity brief blindness did not increase your appreciation for beauty, Mr. Spock.
Come in, Spock. I'm all ready for you.
My orders were to report to Sickbay, Doctor. I have done so. And now I'll go to my quarters.
My orders were to give you a thorough physical! In case you hadn't noticed, I have to answer to the same commanding officer that you do! [brief pause] Come on, Spock. Yield to the logic of the situation.
Stonn. She is yours. After a time, you may find that having is not so pleasing a thing, after all, as wanting. It is not logical...but it is often true.

Live long and prosper, Spock.
I shall do neither. I have killed my captain... and my friend.
[After realizing that Kirk is not, in fact, dead.] Jim! [Catching himself before he displays further emotion] I am...pleased to see you, Captain; you seem...uninjured.
There's just one thing, Mr. Spock. You can't tell me that when you first saw Jim alive that you weren't on the verge of giving us an emotional scene that would have brought the house down.
Merely my quite logical relief that Starfleet had not lost a highly proficient captain.
Yes, Mr. Spock, I understand.
Thank you, Captain.
Of course, Mr. Spock. Your reaction was quite logical...
Thank you, Doctor.
...in a pig's eye!
Insults are effective only where emotion is present.

I am Apollo!
[sarcastically] And I am the Tsar of all the Russias!
Mr. Chekov...
I'm sorry, Captain. I never met a god before.
And you haven't yet.
Mankind has no need of gods...we find the one quite adequate.
Captain, we've got to do something.
We were doing something, until our brave lady stepped in and saved us.
Would it have hurt us, I wonder, just to have gathered a few laurel leaves?
