I have a feeling that something is missing from the Łukasiewicz stuff you’ve been doing because I don’t think that assigning a quantitative degree of truth is all that vagueness really ought to be about. Vague sentences shift their meanings as the context changes. Vague statements can become crisp statements, and accordingly our language can gain more powerful synonymy. As a slogan perhaps, “vagueness wants to become ambiguity”.
