[FRIAM] To repeat is rational, but to wander is transcendent

[glen]

Yes, that's a well-placed example. I recently accused Nick of Foundationalism. But my accusation isn't quite right. It's more like you say the general gist that platforms are good (or useful). The trick is the ability to doff and don platforms, which assumes a plurality of platforms. Maybe it's like a sparse graph in a dense space. Where there *is* a platform on which to stand, that gets you 80% to the place you want to be, don it. Where there isn't one, doff 'em all and walk the graph to the last common ancestor and build from there.

My problem is I'm not creative enough to build my own, and pain tolerant enough that I'm satisfied with even 30% of the way there, building a one-off nobody would ever bother to read or use. So I'm too pluralist ... too willing to play others' games.

I seem to spend a lot of time trying to convince myself of why it can't work, and whether it is a bad fit or something that needs to be fixed in the platform.  What is important, in this value system, is that platforms are good, not that this or that problem gets solved.   I think it is basically the Computer Science value system in contrast to the Computational Science value system.

The conversation seems to be about essentialism. Maybe that's a nice reflection that we're sticking to the OG topic "analytic idealism". But maybe it's Yet-Another example of our pareidolia to see patterns in noise and then to *reify* those patterns. [Re]Abstracting and [re]concretizing heuristics across contexts may well be what separates us from other life forms. But attributions of the "unreasonable effectiveness" of any body of heuristics is the most dangerous form of reification. The superhero ability to [re]abstract and [re]concretize your pet heuristics convinces you they are "properties" or "qualities" of the world, rather than of your anatomy and physiology. Arguing with myself, perhaps Dave's accusation is right. Maybe this is an example of swapping the sign for the object, or reworded prioritizing for the description over the referent, confusing the structure of the observer with the structure of the observed.

I'm used to the idea that the intensives divide out the extensives. But I haven't seen them formulated as higher order derivations from entropy.

One needs some criterion for what is likely, or stable, which in general terms is an entropy (extending considerably beyond the Gibbs equilibrium entropy, but still to be constructed from specific principles), and on the macrostates _only_, the entropy function (which may be defined on many other states besides macroststates as well) becomes a _state function_.

It is precisely the duality — that one is the derivative of a function with respect to the other, which is the argument of that function — that makes it not bizarre that both exist and that they are different.  But as EricC rightly says, if one just uses phenomenological descriptions, why any of this should exist, and why it should arrange itself into such dual systems, much less dual systems with always the same pair-wise relations, seems incomprehensible.  For some of the analogistic applications, there may not be any notions of state, or of a function doing what the entropy does, or of aggregation, or an associated accumulation operation, or gradients, or any of it.  Some of the phenomenology may seems to kinda-sorta go through, but whether one wants to pin oneself down to narrow terms, is less clear.

If you tell me the number of atoms of a particular substance that you have smushed within a given space, we can, with reasonable accuracy, tell you the density, and hence the "state of matter". When we change the quantity of matter within that space, we can also calculate the expected change in temperature.
