Brian, Your inquiries about FL is an uncharted but important one. I'd like to suggest though that your approach is too conventional and 'consistency' is not the ultimate criteria for evaulating it's connection with validity or more importantly - feasability - in context with 'logic' - and

Hi Brian, Your idea of a universal set, in case it works, would indeed meet one of the objection I often raised against Tegmark-like approaches, mainly that the whole of mathematical reality cannot be defined as a mathematical object. Of course this is debatable, and a case can been made

Hi again... In +this+ post, I am attempting to encapsulate all previous posts on sci.logic and here. In a nutshell, my work in FL is going to hopefully provide the beginnings of an answer to what is the universe by at least making a plausibility case for some universal fuzzy set, in conjunction

My main goal is that I seem to need to show that such a fuzzy set theory, one with a universal set, is ++consistent relative to ZFC++ or at least prove that that's not possible (ie, prove a generalization of Russell's paradox). It is proved in Paraconsistent Logic:

From your link. Does 'any theory' in the following quote include theories that involve logics with every MV-algebra as their truth set and every set of syntactical axioms or is this just any theory using binary logic? Could Russell have proved anything in the context of even paraconsistent

I would tend to think that most mathematicians and even more physicists and even more engineers and even more laymen would say that 'just' is a huge, huge understatement. However, from the perspective of Non-Classical logic (be it paraconsistent or fuzzy), that sentence was perfectly formulated,

By Fuzzy Logic (FL), I mean such things as mentioned in these links (perhaps I should have said Many-Valued Logic or Non-classical Logic): http://en.wikipedia.org/wiki/Multi-valued_logic The structure of the truth set is not necessarily the interval [0,1]; it could be an MV-algebra, perhaps

John, I think you're missing the point. MUH is the Mathematical Universe Hypothesis from Tegmark's paper. Fuzzy Logic means something quite precise - it is a mathematical theory where truth values take on a real value in [0,1], which is called a membership function. Brian is proposing something
