This Kirk talk was reminded to me from a previous post.
There is a definite theme here. Possibly against some of the perceived nullifying effects of old school psychotherapy?
For some reason, though, in my head it happened in TOS and Kirk was pretty much talking to himself, resisting effects of a creature that had come onboard and was removing all psychological trauma of the crew. Kirk was the last. It was one of those episode where Spock turns into a hippy.
Can anyone confirm this?
