Apr 23, 2013 at 20:41 comment added Jan Jitse Venselaar @Paul: There is an approach by Heunen, Landsman and Spitters (arxiv.org/abs/0709.4364) where they combine quantum mechanics, noncommutative geometry, and toposes, where one of the main point of toposes is that the internal logic is intuitionistic. I'm not well-versed enough in topos theory to really make sense of that article though.
Apr 23, 2013 at 18:58 comment added Paul Taylor That piece of prose is in the Introduction to the book, which I wrote in a hurry because there had to be an Introduction, so don't pay much attention to it. If there is ever a second edition then the Introduction will go: I am still quite pleased with the way I started off in Section 1.1.

Apr 23, 2013 at 15:25 comment added Mikhail Katz I note that in your "Practical Foundations" you use a similar analogy: "In classical logic, as in classical physics, particles enact a logical script, but neither they nor the stage on which they perform are permanently altered by the experience. In the modern view, matter and its activity are created together, and are interchangeable (the observer also affects the experiment by the strength of the meta-logic)."
Apr 23, 2013 at 15:21 comment added Paul Taylor I suspect that the thinking behind this question is that it is sometimes said that classical mathematicians ought to be willing to acknowledge intuitionistic mathematics in the same way that they do non-commutative group or ring theory. I agree with this professionally, but I do not think that there is a significant mathematical analogy to be made. Howover, I would certainly like to hear from someone who does know about quantum groups, for example, maybe with a substantive positive answer to this question.
