Consider this a reminder for people currently watching Star Trek, old and new.
Logic and controlled emotion aren’t inherent to being a Vulcan. Somehow gaining Vulcan traits, or biologically transforming into a Vulcan, will not make you logical and emotionless. In fact, quite the opposite would happen.
Vulcans used to be warlike, barbaric (as Spock would describe them) and nearly wiped themselves out. It was the teaching of Surak in the philosophy of pure logic, after centuries of war, that made Vulcans what they are today. Vulcans do this by training logic and emotional control throughout their childhood and teenage years. Ultimately culminating in Kolinahr, the final stage to “purge emotion”. But Vulcans still experience emotion, and their state of control is something that requires constant maintenance through meditation and practice.
Vulcans are far more emotional and passionate than even Humans. If a Human so much as houses a portion of a Vulcan’s Katra (the mind/spirit), said Human would struggle immensely to keep their feeling under control.
I’m writing all this because I’m getting the feeling that this very important part about Vulcans is being forgotten (perhaps more-so by the current writers of Star Trek).
No, but it helps. They weren’t evolved to suppress emotions.
Actually there is an episode of VOY that proves they did evolve a special brian region that enables them to learn how to supress emotions
On what are you basing this? Because it’s not the Voyager episode.
Vulcans have biological psych-suppression systems.
Based on all of Star Trek. You can see the links above that Vulcans have been extremely passionate, emotional, and violent before their teachings of logic and emotional suppression.
Or you could just continue ignoring all that.
Did you know Humans also have brain centres that exist for logic and emotional regulation?
The episode I just referenced demonstrates that this is not true.
If you want to be a canon cop, you can’t be selective.
One episode having bad writing doesn’t magically erase every other entire series where Vulcans are as OP said…
Speak for yourself.
I asked you for a direct reference, and you provided a vague gesture.
I provided direct references in OP. You decided to ignore them in favour of one selective moment in Voyager.
None of the episodes you cited stated that biology plays no role in the Vulcan capacity for emotional suppression.
So we have one episode that says it fits, and zero that say it doesn’t.
On the contrary; none of the episodes in all of Trek, up until your Voyager episode, states that a Vulcan’s logic and emotional suppression comes from biology. They do the opposite; Vulcans are biologically incredibly emotional and passionate. The Voyager episode doesn’t even go into detail what that biology is either.
It’s just a brain centre, like any other brain centre, that regulates emotion (humans have one too), and through training the Vulcans use to it suppress their emotions. Unless you explicitly choose to ignore all canon that comes before it.
Even within Voyager it is clear that a Vulcan achieves logic and emotional control through years of training, and that before logic and emotional control became part of Vulcan culture, Vulcans were passionate and violent. Do you deny this well established canon?
