Re: Star Trek Into Darkness review by Steve Burgess
I think it was established early on that Spock Prime was repressing strong emotions and passions in "The Naked Time". And, it was repeated throughout the first series that the Vulcans nearly destroyed themselves because their passions were so strong, and it took a leader named Surak who had exceptional strength and character to begin the reforms that would eventually create the Vulcan that we know.
But even then, the majority of Vulcans we see obviously didn't have perfect emotional control. Why else would they need Kolinahr?
