This is actually not what I would say. With how you phrased it right now, I would question whether this view cashes out at anything. What is the difference between being a non-reductionist in this way and a reductionist? My definition of reductionism is that the laws of physics are all written over a single layer of physical stuff), and you seem to agree with this? (Except that consciousness is an exception?)
The laws of physics describe what happens physically. Yes, fine. But this is just reductionism
within the physical aspect. The difference between a general reductionist and a non-reductionist is whether they then say "and that describes everything that happened".
I would consider the Dooyeweerd's 15 Aspects as a kind of 15-dimensional space. When something happens, it is like a shape in multi-dimensional space. Describing what happened physically is like
projecting that shape onto one axis. But that doesn't describe the whole shape.
Each aspect/dimension is potentially a discipline, with its concepts, theories etc.
I don't think consciousness is an exception to other things. I haven't really thought about consiousness much, but probably my consciousness has Physical, Biotic and Sensory aspects to it.
Or if you consider an abstract concept of consciousness, that is probably a feature of the Sensory aspect, like a concept of mass for the Physical aspect, a concept of a bit for the Analytical aspect, or a concept of beauty for the Aesthetic aspect.
