"it turns out that there is a temporally asymmetric principle,
almost universally taken for granted in contemporary physics, which cannot be accommodated within this orthodox picture. The principle concerned is an extrapolation to microphysics of a familiar feature of the macroscopic world of experience: roughly, it is the principle that the properties of interacting systems are independent before they interact.."

And I think the reason here is simply the old issue of our inability to reason coherently without a causal framework of influence, it may not be the ultimate reality, but it is the only reality we are capable of understanding and comprehending, to use a Kantian/Schopenhauerian style of argumentation.

because of backward and forward in time moving influences on this scale. The problem is that such influences disobey causal principles. We can pay lip service to the reality of such phenomena, but we cannot really conceptually believe it coherently, just like those behaviorists who tried to pretend their own consciousness didn't exist to make the theory work, they are only kidding themselves in the end...

However, the conclusion I would draw from this, is not that we need a better symmetrical account, its just, for me, another example of the unavoidability of smuggling in some asymmetric assumption in any attempt to explain it symmetrically, because the basic principled reality is indeed asymmetric and needs to be acknowledged as such. He is arguing that quantum mechanics works better symmetrically...

Most physicists have taken the view that like the asymmetry of thermodynamics, PI^3 is a product of asymmetric boundary conditions, rather than of the kind of lawlike asymmetry which would
violate T-symmetry..." What he is saying here is that the statistical account of asymmetry is actually presuming an asymmetry already in its account in the form of the PI^3. I think he may be correct on this point..
