My paper, submitted for the Studia Logica Conference in Brussels in December, Logic and the Foundations of Physics, which reflected such an approach, was rejected. I hope that if you or other readers of this blog attend the Conference, they can report if there are any views that go in this direction, or if we are still in a mode of "logic as usual".

I have been saying for years that we should think physically about logic and not only logically about physics. I will try to talk in my post next week about some of these dualities an then we can perhaps have more of a conversation in relation to that. Hi Joseph,

that does sound interesting. I have been saying for years that we should think physically about
logic and not only logically about physics. I will try to talk in my post next week about some of these dualities
an then we can perhaps have more of a conversation in relation to that.

With the possible exception of quantum logic, all other standard logics, bivalent or multi-valent, predicate or intuitionist, are basically linguistic. The exception is my "logic in reality" which is an extension of logic to real phenomena, founded in the dualities and self-dualities of physics that Shahn has written about. My logic is described in my book published in June by Springer Dordrecht called also "Logic in Reality". I think it does a better job than quantum logic per se in describing the logical aspects of macroscopic phenomena. I would be interested in dialogues on the subject. Cheers.
