Was anyone else surprised by how .. 'real' the Cognitive Realm felt in Part 4? I was expecting it to be a lot more mental, but we see land, plants, animals, and travel - if you want to get from one place to another then you actually have to hike there (or take a boat) and Kaladin's Windrunner powers seem to work in the same way as well.
I think the main reason I was surprised is passages like this from WoR:
which suggests that the Cognitive Realm can't be 'touched, seen or heard' (although now we know that's not true) and
which implies that spren / forces from the Cognitive Realm are somewhat responsible for what we think of as physical laws in the Physical Realm. And yet, when we enter the Cognitive Realm, all of those forces still exist, without spren to influence them.
Is this just a limitation of perception, where humans can only see the Cognitive in the way that they'd expect? I don't think the book gives us any suggestions in this direction, given that Syl and Pattern seem to interact with the realm in the same way that the humans do. Is the Cognitive Realm somehow more real than the Physical, with nature in the Physical mimicking that of the Cognitive? That definitely seems backwards, although it would be an interesting twist. The most likely explanation (which I think we've heard a few times, although I can't find a good quote) is that humans somehow created the Cognitive Realm, or at least shaped it somehow so that it would behave as a human expects the world to behave. It still feels strangely similar to the 'real' world, though, rather than being some other plane of existence like I was expecting.
What do you think?
