A recent post talked about the inherent contradiction between what Vulcans espouse and the way they treat other races and concluded that their culture is an open lie.

There are some excellent responses to this thesis, which I feel is a bit exaggerated and based on a misconception. Of course, Vulcans are not homogenous, and we can also go into the what I consider the very plausible fan theory that the differences between Romulans and Vulcans are down to their version of the Eugenics War(s). But I’ll save my ideas about what drove the Romulans and Vulcans apart philosophically for another time.

We know that Vulcans have emotions, but they keep a tight rein on them. Keeping a tight rein of them also inevitably means that sometimes the reins can loosen, and sometimes involuntarily.

I've recently spoken a few times in comments about Vulcan logic and how it's often misunderstood as being similar to when humans talk about logic. So this has prompted me towards writing another post which tries to synthesize most of what I've said about Vulcans over the years on Daystrom in one place - for my own edification and easy reference if nothing else. Given that it’s 8 years today since Nimoy left us, it seems appropriate.

VULCAN LOGIC ≠ HUMAN LOGIC

Diane Duane, in her excellent novels Spock’s World and The Romulan Way, among others, fleshed out Vulcan philosophy and Romulan codes of honor. I should note that Duane’s writings on Vulcan culture and history were tremendously influential on the Vulcan Arc in ENT’s 4th Season and have also made their way into more recent Star Trek series.

What Duane came up with, and I wholeheartedly endorse, is that what is logic for Vulcans is not quite the same was what we humans understand it to be for ourselves.

Human logic is a system of thinking, a method of reasoning. It is defined by clear rules, cause and effect, propositions, inferences and steps. It is a metric - rules of thumb to solve problems, and is not designed as a view of the universe. Rather, it assumes a particular view already, and works from there. Vulcan logic isn’t the same.

C’THIA AND ARIE’MNU - REALITY-TRUTH AND PASSION’S MASTERY

Duane’s idea is that Vulcan logic is more foundational and philosophical in nature. The word “logic” is our English/Federation Standard translation of the word/concept cthia, which literally means “reality-truth”. Cthia is the concept of seeing empirical reality for what it is, rather than what we wish it to be. To practice cthia is to face the universe with the utmost objectivity, without bias or preconception, emotional or otherwise, in order to promote the clearest reasoning and rationality.

This goes beyond using logic to solve problems, which of course it’s still useful for. But it is also a viewpoint that is supposed to be the basis for modern Vulcan culture: to state things plainly, without hiding behind metaphor, to put aside emotion lest it taint the cold assessment of facts. It also demands that one recognize nuance, to take in all the variables and not be rigid about it, to recognize the fact that, while you may be logical in the Vulcan sense, the universe itself may not be, and you have to deal with that, too (more on that below).

This also ties in with Duane’s other term: arie’mnu, or “passion’s mastery”, recently made canon by President T’Rina’s mention of it in DIS: “Choose to Live”. Arie’mnu is often misunderstood by non-Vulcans as the denial of emotion, but it is more about the control of it, to direct the aggression of the Vulcan psyche towards the practice of cthia, creating the conditions for the effective exercise of Vulcan logic.

We also have to recognize that cthia and arie’mnu are ideals, and not everyone manages to attain this, and the degree to which one is able to exercise this varies from Vulcan to Vulcan and even from day to day. Some eschew it entirely - like the v’tosh ka’tur, the so-called “Vulcans without logic” who embrace their emotional side, or keep a looser lid on it. Most Vulcans act cold because the Vulcan heart rages so profoundly that they are taught that to try to play fast and loose with arie’mnu is reckless and leads to a loss of control. That’s why the v’tosh ka’tur are viewed with such suspicion and treated accordingly.

Some even try to exercise what they consider the highest form of arie’mnu - the kolinahr ritual which attempts to purge all emotion from the Vulcan psyche (TMP). Again, this is something that not everyone is able to achieve. Spock tried, but failed because he could not get rid of his emotional attachment to Jim Kirk, and when Vejur called out, it called out to the human, emotional part of him. Spock managed to integrate his Vulcan and human “souls” better in later years, but that’s another story.

SURAK, THE KIR’SHARA AND THE VULCAN REFORMATION POST-2154

Cthia and arie’mnu are Surakian concepts, taught by him during the Time of Awakening, sometime around 350 CE (ENT: “Awakening”, in 2154, is said to be 1,800 years after that time), in order to stop the wars that were tearing Vulcan apart. And we have to remember that Surak’s teachings, in their original form, were lost for a very, very long time. It wasn’t until the mid-22nd century that Surak’s Kir’Shara, the artifact containing his writings, was rediscovered.

So we have to remember that the Vulcans in ENT, who are surly, arrogant, even to a degree emotional at times when dealing with humans and each other, are representative of Vulcans before Surak’s original teachings are rediscovered, so their understanding of cthia, arie’mnu, Vulcan logic and so on are necessarily imperfect. It was only after the rediscovery of the Kir’Shara that Vulcan society became closer to what Surak envisioned it to be. ENT’s Vulcans have to be seen in that context.

But even so, not every one succeeds. Even after ENT we’ve seen arrogant Vulcans, irritated Vulcans, and even angry Vulcans. We’ve seen Vulcans twist logic to their own selfish ends, or to justify repugnant positions. But this shouldn’t be a surprise, and it equally shouldn’t cause us to make sweeping generalizations about Vulcan logic. Every Vulcan is different, and to recognize that is also to practice cthia.

VULCANS LIE

Vulcans lying (and lying about lying) is a - pardon the term - fascinating subject, and I would argue that it actually does come from cthia. Objectively, while Vulcans celebrate Infinite Diversity in Infinite Combinations (which is also a recognition of empirical fact) the fact that they are usually the smartest people in the room and that most races - humans in particular - seem like toddlers on a drunken galactic rampage means that they naturally assume a parental stance, especially in the 22nd Century when their understanding of Surakian philosphy is inexact at best.

And it is perfectly in line with recognizing that reality that they would lie to “lesser races”, just to achieve greater goals in what they think is keeping those races safe or to maintain the peace. Spock lies quite readily in ST II and ST III but that’s always in service of a greater good. For Vulcans, the ends justifying the means, in certain situations, is logical. Rigid morality doesn’t come into it.

Now, I’m not saying they’re justified in their arrogance and condescension - as Spock put it in TOS: “A Taste of Armageddon”: “I do not approve. I understand.”

VULCAN RITUAL IS LOGICAL

If Vulcans are so logical, why do they shroud their past in ritual and custom?

Well, from a Vulcan perspective, one should first ask, "What is the function of ritual?" The usual function of rites and rituals is to preserve traditions handed down from the past, to provide a sense of continuity, to reinforce certain principles and tenets, and as an expression of those tenets and practices even if - at times - the person performing the ritual doesn't quite understand them, but the idea is that with study and repetition, they will understand in time.

In a sense, it's like military drilling, or kata in martial arts. When internalized, ritual becomes like muscle memory, a macro that carries with it all the practices and principles without the need to rationalize every step which, for whatever reason, is inefficient or unnecessary to do so. It is in this function which I think that the first Vulcan ritual we observe in TOS: "Amok Time" serves. Spock says:

SPOCK: The birds and the bees are not Vulcans, Captain. If they were, if any creature as proudly logical as us were to have their logic ripped from them as this time does to us. How do Vulcans choose their mates? Haven't you wondered?

KIRK: I guess the rest of us assume that it's done quite logically.

SPOCK: No. No. It is not. We shield it with ritual and customs shrouded in antiquity. You humans have no conception. It strips our minds from us. It brings a madness which rips away our veneer of civilisation. It is the pon farr. The time of mating.

During pon farr, Vulcan stoicism and their ability to suppress their emotions breaks down and they need external help to maintain civilized behaviour. That's where the ritual of the kun-ut-kali-fee comes in, so even if the plak tow - blood fever - is at full pitch, some part of the Vulcan knows that there is a procedure to be followed which will guide them through the worst of it and out the other side. They don't need to think, to reason out in what way or why this will help them; they know that it works, and they simply need to follow this road.

So this is perfectly logical! Rather than find some way to suppress the pon farr itself, the Vulcans recognize the reality-truth - the cthia - of their biology and come up with a metric to deal with it. Rather than re-invent the wheel at every step, they take the tried and tested route.

The more you think about not wanting to do something, the more your brain has to struggle. It’s like telling someone not to think of a white elephant. So beyond pon farr, ritual allows Vulcans to more easily practice arie’mnu in their daily lives. This also allows them to appreciate music, art, beauty, even games without the attendant emotional attachments. Structure, order, symmetry, clarity: these are all part of what Vulcans find aesthetically pleasing because they reinforce the central tenets of Vulcan logic.

Vulcans are always aware of their emotional, wild heritage and how it can easily explode. So every step of their lives is perfectly ordered and laid out in order to keep this emotional self in check. The discipline is paramount, for without it they believe their civilization as it is now could not exist.

THIS IS THE VULCAN HEART, THIS IS THE VULCAN SOUL

T’Pau said it best (in reference to ritual): "This is the Vulcan heart. This is the Vulcan soul." Fiery passion and razor-sharp intellect wrapped in millennia of history and tradition and discipline to create the highest understanding. And to practice it is to bring a net positive to that passion, to improve the universe. Spock said this in TOS: “The Squire of Gothos”, a line still close to my heart:

SPOCK: I object to you. I object to intellect without discipline. I object to power without constructive purpose.

Vulcan logic is ultimately an ideal - and on a personal note, one I think is really cool and worth examining and even emulating - in the right context, of course.
