Hi Olaf,
I enjoyed the choice of examples in your essay, in particular that of the orchid and moth, and the fact that a solid as a representation of position doesn't require the external definition of a coordinate system. I'm not so sure that your example of a molecule being moved, while a large crystal remains unmoved was a good one though. A crystal lattice is in effect a single, albeit very large and hence massive, molecule. A small molecule moves more than a large crystal simply because its inertial mass is so small that a modest force will accelerate it noticeably. A large crystal will behave exactly the same way, but with an acceleration that is too small to notice. Perhaps it would have been better to refer to something like the fact that a single water molecule only behaves like a molecule, but several water molecules can form a liquid, a solid, or a gas, each with different emergent behaviours.
I very much liked your speculation about the role of different layers of reality inducting the randomness we observe in quantum mechanics. This is similar to some of my own speculations, that I hope we get to discuss sometime.
Regards,
Sundance
