I’ve been going down a little rabbit hole of Twilight today, found your blog and have been thoroughly enjoying your meta on Bella and Renesmee’s powers. Do you have any thoughts on what their powers could truly be classified as? Like, Bella makes sense as some sort of self-preservation thing, but Renesmee’s honestly sounds more like mind control.
I don't really love the classification system that's used in Twilight, as it reminds the nerd in me of how unsupervised k-means AI classification will work: it looks at the data points and says "Okay, these are different enough from the rest and similar enough to each other that they're probably related. Alright alright, this cluster must be blue."
You also, when doing this type of classification, want to tell the computer how many categories it's looking for, which depends on the size of the data set, and the type.
It's not a perfect analogy to what Eleazar is doing, but he reminds me more of a k-means cluster than he does Charles von Linné, who was a brilliant biologist who invented the modern system of naming and categorizing organisms that we use today.
He looks at the gifted vampire he is presented, compares it to other gifts he has known, and assigns a similar category if he finds one that's similar. This, famously, leads to such differences as psychic and physical gifts (which to me is such a "Are you a computer trying your best with unlabelled classification? Are you having a hard time?" thing to which the computer would sadly admit "yes :(") where what's assigned a physical gift and what's assigned a psychic gift seems so incredibly arbitrary and contradictory that I can only assume somebody got ahead of themselves with "A and B are similar. B and C are similar. A, B, and C must be the same category!" and now they have a problem.
As an example: Aro and Edward are similar. They both read your mind. They have clear differences, however, as Aro requires physical touch to do so and Edward requires doesn't, while Aro is able to read all the thoughts you've ever had while Edward can read every mind within the area. You can classify them as mind readers, sure. Now you have a category describing "vampire who can read minds".
Demetri, according to Edward himself, is also similar to Edward. They both sense a person's mind, without need of touch. However, Demetri senses location, Edward doesn't, and Edward senses thoughts, Demetri doesn't. Edward is limited by geographical distance, Demetri is limited by one degree of Kevin Bacon. But if we want to classify them, then mind sensing might be the best way to do so. Both can stand in a room and, without moving a muscle, have a sense of every mind around them and they will gain information others can't.
Aro and Demetri, however, have very little in common. Their common denominator is that it "has to do with the mind".
Now for added difficulty: how do we classify Renesmee? She can by touching people convey her thoughts. This seems to be something she needs to block rather than choose to show, as people can touch her to see her thoughts when she's unconscious.
Is she then in the same category as Aro and Edward, or we create a parent category for "something to do with mind reading" and Aro and Edward are a shared subcategory for reading the minds of others well Renesmee is in sharing her mind, or is Edward off on his own with non-tactile mind-reading while Aro and Renesmee get a shared subcategory for tactile mind-reading-related? Does Demetri belong higher up in the tree, at the "mind sensing" junction before the others split off into the "something to do with mind reading" subtree?
The reason why I ask these questions, is to illustrate how meaningless it all is. There are so few gifted vampires in Twilight that we don't have enough data points to start looking for meaningful classification or similarities. Aro, Demetri, Edward, and Renesmee are all unique, with gifts unique to them. God knows that if my theory that Renesmee's real gift is to make people not want to hurt her, then she's suddenly in the same camp as Renata, who makes people forget what they were doing when they try.
Except Renata's gift is to disorient people when they get physically close, Renesmee's is to make them not want to hurt her in the first place. If we classify them together, then I don't think Renata can be classified as a shield anymore. The impenetrable space around her would only be a materialization of her gift, which is to dissuade attackers from entering that space.
Which brings me to the next point: the so-called psychic vs. physical gift division.
It depends entirely on how you classify these gifts. What makes Jasper and Alice's gifts physical? Jasper can manipulate and sense emotions, how is that different from Alec, Jane, Kate, and Zafrina manipulating your sense reseptors? Alice can see things which may happen, how is that physical if Edward seeing thoughts and Zafrina creating elaborate illusions isn't?
Benjamin, surely, must be physical. Except his gift is the only one of its kind in canon, no similarities to anyone else, which means he proves that vampire gifts can truly be anything and there's no point in trying to classify them in relation to one another when the population is so small and the unknown potential for gifts so vast.
I think I have argued here in favor of tags, or attributes: you identify something a gift can do, and you don't try to draw similarities, for yonder lies nothing but subjective opinion.
Renesmee can be similar to Aro for "shares thoughts by touch", to Jane by "imparts illusions on one individual at a time", potentially to Renata for "dissuades attackers", and is canonically compared to her father's gift. It depends entirely on how you interpret and want to classify their gifts. And sure, you can do that, no one is stopping you from classifying in any way you want, but the trouble is that you now have a system that's extremely vulnerable to expansion and changes to entries.
There's also the matter of usefulness - the tracker category, which encompasses all vampires who are good at finding others, is a useful one. Some vampires will be able to use their gift, whatever it is, to find you, others won't. I respect that category. I also respect calling Aro and Edward mind readers, it's what they are.
What I don't respect is wanting to categorize every gifted vampire, nor attempting larger classification and to cluster them. The similarities are just that, similarities.
