Yeah, it seems quite a bit narrower (but that's from my non-native/non-proficient perspective). There seems to me to something that is hard to put into words about "ilusion".

As a non-native and non-proficient speaker, there does seem to me to be something missing from those translations. I'm not sure if it's because it sounds like "illusion" in English, but I get the sense there's something almost visual/experiential about "ilusion". It's hard to pin down exactly what!

And I'm someone that used to be a bit precious about people coming from other areas that not citing every bit of (what I thought was) important literature in "my area". Sometimes, of course, people could do with actually reading what's been published on a topic before.

I think there's some work from people outside one area where they don't engage with all the finer points made in that area, but sometimes this can actually help them be most insightful as they don't get bogged down in the points the literature has taken to be most important...
