Vulcan pacifists: I'm jumping ahead here, but the line that Spock is a pacifist in "The Slaver Weapon" struck me as not really accurate. There are several episodes where Spock decides that the logical course of action is violence (Corbomite, Balance of Terror, reluctantly in Arena, and Errand of Mercy to name a few). And his father would be quite capable of killing if the situation called for it.
You do realize that the TAS episode
The Slaver Weapon was just a retooling of Larry Niven's
Tales of Known Space (a fairly consistent fictional Univese onto itself as well - the Larry Niven
RingWorld novels take place in the same universe/continuity) shot story by the same name, right.
The TAS script just subtitutes McCoy, Uhura, and Mr. Spock for the non-Kizinti characters (with Mr. Spock in the role of an alien from a non-humanoid race known as 'The Puppeteers - which if you have read the original short story is rather funny IMO - and is prett much the reason why the Spock was written the way it was for that TAS episode.)
The funny aspect is - in Larry Niven's ToKS Universe, Pupeteers aren't Pacifists per se, there extremely technically advanced (they are one of the eldest races in known space) Xeno-phobic, and obverly cautious non-risk takers. In Nivens Universe, there's been an explosion at the core of the Milky Way Galaxy that's expanding out in all directions at the speed of light (and the other races heard this FROM the Pupeteers - and then used FTL ship to verify it was true); and wiping out systems as it hits them. The Humans and other races with FTL capacity aren't too concerned and it's still many tens of thousands of years until their homeworlds are threatened - so they feel they have time. The Puppeteers on the other hand do not trust FTL technology (although tghey have developed the best FTL drives); and also don't want to move from or loose their Homeworld; so they used their highly advanced tech; are moving their Homeworld itself away from the incoming blast at lightspeed, and expect to do so indefinitley.
Also, they consider any Pupeteer who works with such risky advanced tech (like FTL drives etc.), or who decides to leave their Homeworld without a life/death reason, insane; and once they leave, they can't rweturn as they are 'dangerous'; (and usually the ones that leave are still overly Xeno-phobic; and still don't like to take undue risks, and are nervous when using FTL tech, etc.)
^^^^
I relate all this because the Pupeteer in the story is one of those so-called 'insane' Pupeteers; and this is the character Spock in written in for in the TAS version.
But my point - in the TAS version 'Pacifist' was inserted for 'Cowering Coward' <--- which was what te Pupeteer was for the most part. In the original story, the Pupeter DOES attack and break the Kzin Captain's ribs; but only because he was so scared by the Kzin's actions - he felt he had no choice.
My point? In the end, I don't knoiw if it was GR's or ANY of the original Star Trek production staff to say 'Vulcans are all pacifists' per se; but TAS;
The Slaver Weapon introduced it as a fact; and since a lot of the people later involved with the TNG era series productions, it goty 'worked in' to later series lore regarding Vulcans it seems.
