I think that in the Spiritual realm a person's spiritweb sort of manifests as a collection of "nodes" which are the Forms of their body/mind/subconscious, and these nodes are connected by "lines" which are interactions between the pure Forms. These lines are what actually make up the person's character, how the body is "supposed" to be (barring accidents/disease, basically what magical healing attempts to restore the body to), as well as what interactions with investiture the person can use (what magic systems they have access to)

Am I completely off base here or should I keep thinking about this?

Brandon Sanderson

This is a good line to be thinking along.

So harmonium, we have a working theory that the reason it's so volatile is because some of the subatomic particles are associated with Ruin and some of them are [of?] Preservation. Is that true?

Brandon Sanderson

Yeah, that's basically what's going on is that it's creating a very unstable metal. Now, it is in the nature of the Cosmere not a compound but an element. But, you could call it a subatomic particle sure. It's very volatile because it is in nature spiritually in contrast with itself. And so though it is a single element rather than a compound, the spiritual nature is not happy as it is, and you can set up in the physical realm, through reactivity things that would just rip it apart and really your energy is not, your energy in that is actually pulling from the Spiritual realm, and so that's why it can be so much more explosive than even the chemistry would account for.

Ironeyes

So it's not that the subatomic particles are invested, it's that they have a spiritual identity which causes them to...

Brandon Sanderson

Yes.

Ironeyes

So then it's not creating an oxide because after the spiritual energy goes away from the explosion then it's a different metal, right?

Brandon Sanderson

Right, and...

Ironeyes

So you can't find harmonium oxide in the water afterwards.

Brandon Sanderson

Right right right right. Because it's not, it's, yeah. But you might be able to find something else, which is really relevant to the Cosmere. And to Scadrial.

Ironeyes

So the core elements, the core particles, having extra repulsion causes them to have a nuclear potential.

Brandon Sanderson

I would not call it nuclear because it's not the same exact thing. But there is a Cosmere equivalent. To - I mean, you could do nuclear power just the same in the Cosmere, but since we have a third kind of state of matter, right? Matter, energy, Investiture. You have a third axis that, you know, you can release energy from matter, you can release investiture from matter, and things like that. So it's similar, but following its own rules that I have a little more - that are controlled by me, right, that are built on this idea. So once you add *inaudible*, matter now can exist in this third state, you get all sorts of weird things, which one of the things that happens is, you can get an energy release in sort of the same way. A reaction, I'm not going to call it a nuclear reaction, but of the same vein.

What is the difference between a person's Spiritweb and their spiritual DNA? Is there a difference?

Brandon Sanderson

Soul, generally used in the cosmere, is a spiritual or philosophical term. It refers to the part of a person that continues to exist after death, or to the "being" of the person in a philosophical term.

A Spiritweb is a measurable, quantifiable thing in the cosmere. (Granted, it's not easy to do either to one, but it can be done.) It is a scientific term, though because the cosmere hasn't reached modern scientific understandings yet, there is a lot of overlap between science, philosophy, and spirituality.

This way, acknowledging that a person has a Spiritweb does not require an atheist/humanist to affirm religious ideas or concepts--like acknowledging that the Vessels/Shards exist does not require also affirming that a capital G God exists.

The separation of the two is necessary to allow people like Jasnah to not be undermined by the text. It wouldn't be right of me to work for having representatives of viewpoints contrary to my own if the very foundation of the magic systems and physics proved them wrong.

So, in short, you can measure a Spiritweb. Whether a person actually has a soul or not (even in the cosmere) is subject to your own personal philosophy on the idea. Even ghosts and other persisting personalities after death, like certain individuals who shall remain unnamed, have a very real and rational magic system explanation for their existence.

Is a Cognitive Shadow essentially Investiture filling in the molded pattern of a Spiritweb to the point where it resembles the initial person?

I'm interested in the implications with respect to personal identity--the "soul" would be one of the competing answers for the question "what am I," but some argue for psychological continuity and others for biological continuity. A Cognitive Shadow seems like it might better fit the Psychological Criterion, since it seems like Investiture replaces the biological body as the source of living and experiencing things.

Brandon Sanderson

You're getting into things that are subject to debate among people in the cosmere. Most shadows would insist that they're the same person. Others would dispute this, saying they're essentially a spren--a bit of the power that came alive like you said, taking on the personality of the person when the person themselves died.

BipedSnowman

Like uploading a brain to a computer. Made of Investiture.

Brandon Sanderson

A fitting analogy.

Aurora_Fatalis

Does it matter what kind of power it was that filled the gaps? Like, if you were a normal human and made a Cognitive Shadow fueled by AonDor, would you be more able to "possess" a modern computer than if you were made a Cognitive Shadow by - say - Odium?

Brandon Sanderson

This can matter. Shades from Threnody, for example, work differently from Returned, who are different from Heralds. But all are Shadows.

Overlord Jebus

Is all Investiture in the cosmere associated with a Shard?

Brandon Sanderson

Yes, well, okay. So this is a complicated one. *pauses* So, Investiture predates the Shattering of Adonalsium, all Investiture was from Adonalsium, all Investiture got assigned to one of the 16 Shards when Adonalsium was Shattered. Some of the Investiture was not on Yolen but location is irrelevant. So Investiture is related to Shards even on planets where none of the Shards are inhabiting. 

Overlord Jebus

Are they aware of that Investiture?

Brandon Sanderson

That's part of the whole seeing into the infinite, being beyond even the power of a Shard. So, technically you could make the argument that Harmony could feel the sense of Preservation on every world in the cosmere, right? Because the building blocks of all life and creation are these things.

Overlord Jebus

So the Shard of Preservation embodies all preservation in the cosmere?

Brandon Sanderson

Yes but he just can't do that, right? Like, he's not infinite. The Vessels are not, even if their minds are enormously expanded by holding a Shard, they are not infinite. The Connection is all there in the Spiritual Realm.

Questioner

I think there's a flaw in my understanding of Cognitive Shadows. I assume that... they would have more visibility into the Cognitive Realm, like a Herald would be able to see spren more easily, that kind of thing. Is that incorrect?

Brandon Sanderson

That is incorrect. A Cognitive Shadow simply means a copy of the Cognitive side made by a deep amount of Investiture. And everybody has a Cognitive side. Basically it's a fake soul. Or, fake is the wrong term. Fake is the wrong term. Even in-world they don't know if it's really them or not. It is Investiture has replaced the Investiture that is fleeing from them as they die, or enhancing it in some way to keep it around. So some Cognitive Shadows trapped on the Cognitive Realm are going to be-- have a lot of Cognitive-- I mean, they're there, right? But some Cognitive Shadows inhabiting a body in the same way that your mind inhabits your body, the way the cosmere works... So a Herald is going to feel like they are alive just like-- but their soul has been somehow transformed. It's not really transformed, it's been reproduced or copied by an injection of Investiture...

And I'll say for the purpose of the recordings, I haven't canonized any of that terminology that I just used about Cognitive Shadows. I'm just talking about it, I'm not necessarily saying that this is how you are supposed to refer to it. You can refer to it however you want. I've often used the metaphor of how fossils get made. When a fossil is made there is a pattern and it is slowly replaced with another substance that is stronger and more endurant, and has the shape of it, but is it still the bone? When you have a fossil bone is it the dinosaur bone? In most cases no, but yes. It's the ship of Theseus sort of thing again. Is this the bone or is it not? Is this the soul? Is this the person or is it not? That's the same sort of thing is happening with Cognitive Shadows. And it's happening on all three Realms to an extent, though of course the body is not. The body stays. It's happening on two Realms. It's happening Spiritually, mostly Cognitively.

BlackYeti

Can I ask you about the body of a Shard in the Physical Realm? About the different states of matter. What determines the state of matter that they are in? Because I've been reading the bits very carefully, and I haven't noticed much in terms of temperature difference.

Brandon Sanderson

The idea for me working on this was that they transcend-- They permeate everything, right? They permeate all life on all the Realms. And that there are manifestations of them that leak out, and it's kind of like they make-- they appear there in the various states but-- When you say that you've got the gas, you've got the liquid, you've got the solid: but you've also got inside of you, and inside of that plant, and like-- they're everywhere. And so what determines it? In my head it's just like when some of that power permeates, some of it distills, just like water. There's some water in the air, there's some that freezes: that's temperature. But it's not always temperature whether it's in the air, or whether it's falling. Imagine a Spiritual version of humidity, that is influenced by what's happening on the Spiritual Realm and the Cognitive, and that's what you'll get.
