MIND THE GAP. “Some physicists and philosophers claim that from a fundamental viewpoint, higher levels are ‘nothing more than’ an aggregation of lower level phenomena, i.e. they will all emerge by coarse-graining. However, some higher level causally effective variables cannot be obtained in this way, as they are demonstrably not coarse grainings of lower level variables.”
