So what's the deal with Spock and lying? In "Star Trek IV", there's that memorable scene of his verbal joust with Kirk and the marine biologist where a lot of attention is drawn to the fact that he can't lie. However, in "This Side of Paradise", he lies to the woman on the planet about everything being fine on the ship (after Kirk has provoked him into fighting, losing the influence of the spores in the process, and betraying her), and in "The City on the Edge of Forever", he seems perfectly comfortable (in very similar scenes to the "Star Trek IV" scene) supporting Kirk in lying to the locals and Edith Keeler about his appearance/background/actions to cover up the fact that he's an alien/working with futuristic technology.
So was this just a one-time adjustment of the character in "Star Trek IV", or were those other instances continuity errors for a character that is supposed to be incapable of lying? I wonder if anyone has ever seen it definitively established anywhere that part of Vulcan nature is that they cannot lie, or if Spock's compulsive truth-telling in the truck was just the writer taking liberties with the character for the sake of effective humour. And I hope any TNG fans that may be reading this got the little reference in my thread title.
