Hi Jochen,
Thanks for your reply. However I still don't get where your Finiteness and Extensibility principles enter your prove of the impossibility of Assumption 1.
Do you think your principles are connected to the impossibility of copying the whole information in quantum systems? So in your chair example, I was thinking, the information of weight, form, size etc. actually already exhausts all the properties, that make a chair a chair. What it makes classical is, that this information is available abundantly/redundantly, whereas this is not the case for quantum objects.
The reason for the the necessity of such epistemic restriction remains unclear. And might be not further justifiable than by the empirical evidence.
However the justification of why such epistemic consideration should have an effect on the ontology, cannot be in my opinion, by the way we (only can) view the world. This makes the whole picture a bit to anthropocentric. Don't you think? The objective quantum mechanical phenomena like super conduction, stability of atoms, etc. cannot be because of epistemic limits in the knowability the underlying world.
In my essay I probe the possibility, that the underlying objective 'reality' is emergent from relations between emergent objects themselves. Something like this could justify an epistemic impact on the underlying structure. I'll be curious on your comments on my essay.
