I really like this line of thinking. I don’t think it is necessarily opposed to the typical map-territory model, however.
You could in theory explain all there is to know about the territory with a single map, however that map would become really dense and hard to decipher. Instead having multiple maps, one with altitude, another with temperature, is instrumentally useful for best understanding the territory.
We cannot comprehend the entire territory at once, so it’s instrumentally useful to view the world through different lenses and see what new information about the world the lens allows us to see.
You could then go the step further, which I think is what you’re doing, and say that all that is meaningful to talk about are the different maps. But then I start becoming a bit confused about how you would evaluate any map’s usefulness, because if you answered me: ‘whether it’s instrumentally useful or not’, I’d question how you would evaluate if something is instrumentally useful when you can only judge something in terms of other maps.
I’d question how you would evaluate if something is instrumentally useful when you can only judge something in terms of other maps.
Not in terms of other maps, but in terms of its predictive power: Something is more useful if it allows you to more accurately predict future observations. The observations themselves, of course, go through many layers of processing before we get a chance to compare them with the model in question. I warmly recommend the relevant SSC blog posts:
