Well I think any non-positivists, physicalists, naturalism-ists can say that too.
I just wanted more clarity on the meaning of space and time as about
in the head, not
outside it. Clearly, what we perceive is embedded in what is going on in our heads. Clearly we cannot perceive / experience everything, every event in the physical reality outside our heads that makes a difference that has an effect on other things in reality. But nonetheless, I think what we do experience, or at least a significant amount of it has a broadly consistent mapping to specific things that actually go on. To me, that is enough to say that we see real stuff in a weak sense. I think there is no observable intrinsic fact-of-the-matter about representation, only a dynamic statistical coupling between brains and the world which a scientist or philosopher can cash out as representation. The coupling is enough. If I think of veridicality weakly in terms of a kind of coupling or mapping then there is not really a sense that I could exhaustively couple a system to the rest of reality and have it miss anything about reality. When stuff is missed, it because there are couplings missing that give us novel information. Space and time can also be seen in terms of these kinds of couplings, at least the concepts we have made reasonably precise by measurement (i.e. objective time). My subjective sense of space and especially time may be more fallible or is different for various reasons (e.g. speculatively: because time and space are inferred through informational properties of the brain which can be easily perturbed, e.g. if I close my eyes, I lose some of the information required to specify physical space (at least at some allowable resolution) and become more reliant on say body information than I normally would; if subjective time could plausibly related to information flow (e.g. something like entropic time by ariel caticha, possibly), then information processing in my head may distort my sense of time).
So maybe there are discrepancies between objective time "inside" and "outside" as it were but only in some sense that informative couplings have been missed to some part of reality. Good example is obviously relativity phenomena like time-dilation. Maybe the way brains work or learn over time mean that mappings or couplings can be established or parcelled out in different ways; but nonetheless these are just different mappings to events that actually occur, and they are overlapping or inter-relatable so that even though I may be measuring in inches or centimeters, because they are being mapped to the same stuff in reality, there is no sense that these different perspectives are telling me anything new or different about space. And there is nothing else to know about space beyond my sensory boundaries unless that thing to know about space makes some physical difference (because space is physical) to observations and theories and experiential perceptions.
Yes, I can make sense of the fact that there is stuff about reality that I and no one else can see right now, but that doesn't mean it isn't in principle mappable or coupl-able. Seems what you are saying is that there is some sense in which
any kind of coupling misses something about the physical reality of time. But to me, that doesn't make too much sense because it seems to be saying that there are events out there that don't affect anything. In quantum theory, maybe there is an interesting exception in the sense that couplings disturb reality, but from my perspective of quantum theory, this isn't intrinsic to how reality (fundamentally speaking) works but just reflects a kind of very persistent kind of physically confounding effect not in principle different to the kinds of measurement confounds in any other kind of science; for instance, observer or hawthorne effects or demand characteristics in psychology (one might note, for example, that methods like weak measurement and other ways of getting weak values can be seen as approximating information about the undisturbed quantum state, so in some ways this is an example of avoiding measurement disturbance comparable to if one had some kind of technique for avoiding demand charcteristics [like observing someone who doesn't know they are being watched]).
So there is nothing more to say about the metaphysics of reality beyond our best scientific models that supervene on the physical — Apustimelogist
Well, I have come to the conclusion that if we cannot say more about reality than models that in some sense couple to it, there is nothing more to say about the metaphysics than those models themselves, which happen to be the scientific ones. I don't think science is in principle different from the rest of knowledge, so I wouldn't inherently rule out other areas; you can talk about history, anthropology, the study of religions, the analysis of sports as valid areas of knowledge, but its clear they are further away from the topic of metaphysics than physics is - and historical events, human behaviors sit on top of physics.
