Mirror Spock quotes from Star Trek: The Original Series

Spock

Take D'Artagnan here to sickbay.

Spock

[to Captain Kirk] You're the captain of this ship. You haven't the right to be vulnerable in the eyes of the crew. You can't afford the luxury of being anything less than perfect. If you do, they lose faith and you lose command.

Spock

After what this ship has been through in the last three months, there is not a crewman aboard who is not in need of rest. Myself excepted, of course.

Spock

On my planet, to rest is to rest — to cease using energy. To me, it is quite illogical to run up and down on green grass, using energy, instead of saving it.

Spock

I realize that command does have its fascination, even under circumstances such as these, but I neither enjoy the idea of command nor am I frightened of it. It simply exists, and I will do whatever logically needs to be done.

Spock

It is impossible for Captain Kirk to act out of panic or malice. It is not his nature.

Spock

Insufficient facts always invite danger.

Spock

Superior ability breeds superior ambition.

Spock

[To a guard] Sir, there's a multi-legged creature crawling on your shoulder. [Uses Vulcan nerve pinch on guard]

Spock

I have never understood the female capacity to avoid a direct answer to any question.

Spock

I've never stopped to look at clouds before. Or rainbows. You know, I can tell you exactly why one appears in the sky, but considering its beauty has always been out of the question.

Spock

I have a responsibility--to this ship, and to that man on the bridge. I am what I am, Leila. And if there are self-made purgatories, then we all have to live in them. Mine can be no worse than someone else's.

Spock

Jim, madness has no purpose, or reason, but it may have a goal. He must be stopped, held, destroyed if necessary.

Spock

I am endeavoring, Madam, to construct a mnemonic memory circuit using stone knives and bear skins.

Spock

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.
