I love how the spiritual center of Vulcan society is the pursuit of logic. I love this agnostic/atheist approach to religion because that’s what it is, and I especially love how it’s clearly not a perfect belief system.
I feel that a lot of atheists have this idea that if theistic beliefs completely disappeared the world would become like a utopian society, and in many ways it would. Unfortunately, it’s been clear from the jump that Vulcans have a massive superiority complex, and share a collective shame over being “Vulcan” enough, with a penchant of being overly prideful.
They have illogically moralized logic as a concept. “If I’m not Vulcan enough I’m a bad person.” It doesn’t even matter if what they did from emotion harmed anyone. Acting on emotions is shameful.
Then you have the various sects of Vulcan spirituality. You have the Logic Extremist, who justify acts of terrorism as the logical conclusion to keep Vulcan culture pure and unchanged by outside influences. You have the Kolinar Monks and Nuns who dedicate their lives to eradicating all emotions from themselves. Then you have the Vulcans without logic who want to express emotions.
A lot of fans seem to forget that it is completely realistic for Vulcans to act on a spectrum. Because they seem to forget that logic is a spiritual practice for them.
There are going to be individuals who take logic extremely seriously and others who may be a bit more relaxed. Like how every major religion has a dogmatic view and a progressive view.
I have two favorite examples of this.
T’Pring’s parents to start with. You have the mother who expects everything to be traditional and done perfectly to the smallest detail. She expects her children to express zero emotion no matter how cutthroat her criticisms are. Then the father who is so obviously happy to be on the Enterprise, loves the food, and is terrified of upsetting his wife.
This father lets his children smile in the house, as a treat, if the mother isn’t around.
T’Pring also seems to struggle with suppressing emotions in regard to her mother. This woman is an essentially a physiotherapist for Vulcans who have committed crimes from a lack of emotional control, AND SHE IS STRUGGLING.
My personal favorite is V’Lar from Enterprise. V’Lar is warm, kind, and even makes a joke at the dinner table. T’Pol who is much stricter in practice is horrified.
I guess what I’m trying to say is if you want to write a Vulcan but feel like it would be too difficult, go ahead and go for it. Because there’s no true pure logic Vulcans. They all have personalities and their personal journey with logic is going to be unique to them.
