Sure. But,

  1. The way I see causal language being used doesn't suggest to me a demystified understanding of causality.

  2. Maybe I'm being dense but it seems to me a non-metaphysical account of causality won't a priori exclude backwards causation and causality loops. In other words, even if we allow some kind of deflated causality that won't mean Newcomb's problem "makes no sense".

Oh, I wasn't agreeing with taw on that. Just responding to your association of causation with metaphysics. I don't see Omega breaking any causality, whether in a metaphysical or statistical sense.

As for excluding backwards causation and causality loops -- I'm not sure why we should necessarily want to exclude them, if a given system allows them and they're useful for explaining or predicting anything, even if they go against our more intuitive notions of causality. I was just recently thinking that backwards causality might be a good way to think about Newcomb's problem. (That idea might go down in flames, but I think the point stands that backward/cyclical causality should be allowed if they're found to be useful.)

I think we agree down the line.
