Re: Empirics and Life



Judith,

I don't think you understood what I was aiming at. I was trying to illustrate how physicists narrowly define objectivity, and why it is not really inconsistent with your more general view that everything is ultimately subjective. As I said, that is not the issue we should be discussing. All physicists really worry about is satisfying the Hertzian condition for all possible observers. That much I think Rosen would agree is necessary for a good model. That is why he spent so much time clarifying what the modeling relation is in more detail. The controversial issue is what types of formal model and what types of encodings (observables) actually can satisfy the Hertzian condition for living organisms. He shows that the Newtonian state-determined dynamics and simple physical observables cannot. I agree. In my opinion, the relevant problem is that we as yet have no specific Rosennian models of organisms.

I suggested that we need to work on clarifying the type of model Rosen had in mind beyond his abstract graphs. In my opinion, they are general epistemic models from which we need to derive more detailed models specific enough to test by experiments.
