Trying to recall the episode where at the end, Kirk et al confronted the aliens they were trying to defend. The aliens refused to fight for themselves for some philosophical reason. Any ideas?
KIRK: Is that's all you can do, smile?
AYELBORNE: You are free, Captain.
KIRK: I want to know how I'm free, and why.
SPOCK: Indeed, there are several questions I would like to ask as well.
KIRK: This idiotic placidity of yours, your refusal to do anything to protect yourselves.
AYELBORNE: We have already answered that question. To us, violence is unthinkable.
