I’m mostly curious to see if he has any late Wittgenstein, or whether it’s all early Wittgenstein. Given the Tractus is of early Wittgenstein, I’m surprised to hear it as a basis for this work. Russell’s paradox was brutal against the Tractus; it’ll be interesting to see what Subahibi takes from it. I’m guessing by “based on Wittgenstein”, as lots of people claim (have any of them actually read Wittgenstein? Unless I’m vastly underestimating the average reader, I doubt the majority of people have bothered), it’s probably referring to some association between logic and language, not so much Wittgenstein’s thought in itself. Since he kind of abandoned the whole thing later.
By the way, we did have a topic where we discussed language earlier in Rokkenjima, and I did a brief overview of early v late Wittgenstein there, for anyone who wants to read it. It might not be a very good explanation, given how it changed nothing in the discussion, but it is an explanation.
