Brief note on physics, you can prove mathematically that relativity and quantum field theory are incompatible models because you can’t construct a renormalizable quantum field theory in a curved space time.

That's really good to know!

I was really just taking issue with the previous reasoning that one could use the epistemological difference of quantum mechanics as a model to justify a need for dialectics beyond Marxism.

I don't see it that way either. The question in the thread was about more recent scientific discoveries possibly modifying the dialectical view. So I suppose I tried to answer it as impartially as I could, and I assumed the biggest challenge to the theorists living, as it were, in the Newtonian age, Marx and Hegel included, was quantum mechanics. There is also cybernetics, but that's a whole different issue. I love Bateson. But personally don't think one has to commit to one paradigm at the expense of all others, as long as those still work and explain things.
