Over at The American Thinker there is an article entitled Why Conservatives Will Miss Spock. Go here to read it. I am afraid I found it fairly unsatisfying. However, there are examples of Spock giving voice during Star Trek episodes to fairly conservative viewpoints. Here are some of these instances:
1. Balance of Terror-Sadly, war sometimes is necessary:
War is never imperative, Mister Spock.”
- – McCoy, after Spock agrees with Stiles on attacking the Romulans
“It is for them, doctor. Vulcan, like Earth, had its aggressive, colonizing period; savage, even by Earth standards. And if the Romulans retained this martial philosophy, then weakness is something we dare not show.”
- – Spock, responding to McCoy
2. Space Seed-Freedom is better than rule by even an able dictator-
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 his 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.
3. Mirror Mirror-Civilization is better than barbarism-
Spock: It was far easier for you as civilized men to behave like barbarians than it was for them as barbarians to behave like civilized men.
4. Whom Gods Destroy-All men-sentient beings-are created equal-
James T. Kirk: They were humanitarians and statesmen, and they had a dream– a dream that became a reality and spread throughout the stars. A dream that made Mr. Spock and I brothers.
Garth of Izar: Mr. Spock, you consider Captain Kirk and yourself brothers?
Spock: Captain Kirk speaks somewhat figuratively and with undue emotion. However, what he says is logical, and I do, in fact, agree with it.
5. A Taste of Armageddon-Sometimes the best diplomacy is superior firepower-
Spock: Practicing a peculiar variety of diplomacy, sir. [Fires phaser]
6. This Side of Paradise-Males and females are different–
Spock: I have never understood the female capacity to avoid a direct answer to any question.
