But you are just arbitrarily choosing here what obtains, “whether any humans are involved or not.” What is your criteria, and why is it valid, for saying “sweetness” only obtains when humans are involved? Is it not, however you slice it, merely an assertion?
Here’s a “map”
Wetness1: the underlying physics, objective properties of water that obtain in the same way, no matter what labels are used for it. (the territory)
Wetness2: the human concept we use to label Wetness1, the “map entry” that points at the territory
Applying this to “sweetness”:
Sweetness1: the underlying physics, objective properties of water that obtain in the same way, no matter what labels are used for it. (the territory)
Sweetness2: the human concept we use to label Sweetness, the “map entry” that points at the territory.
In the discussion of “sweetness”, Dennett’s (and my, and evolutionary science’s point) is that Sweetness2 doesn’t point to Sweetness1 because of any intrinsic “sweet” (i.e. pleasing) feature of Sweetness1, but points there because it’s beneficial for evolutionary reasons (it’s high-energy density fuel).
Qualia are not the physics. The map is not the territory. For “wetness”, the emergent properties (Wetness1) emerge as they do, no matter what you call it, but nevertheless have properties that are not (trivially) derived from hydrogen and oxygen atoms. Dennett was focusing on qualia. I’m focusing on the underlying physics, regardless of labels or subjective assessments. We are wondering where
those physical properties come from, not the labels or human concepts.
Furthermore, “viscosity, friction, surface tension, etc.” are all themselves concepts, just as “sweetness” is a concept. Granted, they are concepts we use to deal with reality, but, according to your view, “perhaps we are not hard-wired to understand reality as it really is.”
Perhaps not. The degree of understanding is established in the model performance.
What, then, is your criteria for what we can understand about reality, and what is merely relatively conceptual, or “sweet”?
Beyond what is axiomatic (“I am conscious”, for example), what we can understand about reality are those propositions which which perform as (components of) models for that reality, where “performance” means empirical alignment, prediction, and liability to falsification. There is no “pre-known” limit or a priori perimeter. We work form the inside out, from ignorance to knowledge, and and our knowledge extends just as far as we can demonstrate that knowledge to
be knowledge.
Again, on the one hand, you use empricism when it suits your purposes. Then again, when it points to a necessary cause of the universe - when sense experience shows that everything which changes is changed by another - you draw back and say that perhaps things just come into being for no reason at all.
We have no empirical knowledge of what happens “beyond” this universe, or even an inkling if that term (or any substitute you could name) is even meaningful. None. We notice, locally, that a kind of symmetry and isotropy obtains: gravity appears to apply consistently here and any other place we’d care (or are able) to test it. But we understand that those dynamics obtain in a physical context (STEM), and beyond that, we don’t and can’t know what, if any of that, applies. Not probabilistically, not intuitively, not no how can we establish properties or dynamics beyond our local physical context.
Gravity may not be symmetric and isotropic as we think it is. We just don’t have any evidence that contradicts that principle in our various tests and means of measurement (and some of them are very large scale). We haven’t and can’t test it everywhere, so it an inductive conclusion, going from the specific to the general. In terms of cosmologies, we have zero specifics to begin with in going to the general, religious intuitions or dogma notwithstanding.
Why are you justified in assuming sense experience leads to truth on some occasions, and at other times stating that sense experience fails, because, when faced with the “brute fact” of reality, it is helpless to lead to knowledge? I’m failing to see how this distinction is not merely your subjective, arbitrary opinion. Could you please demonstrate the validity of your reasoning/thought process here?
The metaphysical gambit is that our extra-mental reality is intelligible to some degree. It’s unjustified (if hardwired into our biology), and may be a failed hunch, but that gamble is predicated on the performance of any models we might develop as the index of “intelligible”. It’s totally subjective to suppose that “reality is real” (even if, again, it’s hardwired in our biology), but once you accept the idea that objective reality obtains outside the mind (subjectively), the performance of models can serve as your “scorekeeping”.
Given that, in contexts where we don’t have access to evidence or empirical feedback from extra-mental reality – say, for example, in wondering ‘what made the universe?’ – we understand that such knowledge is unattainable, not just in practice, but in principle. That’s subjective at the root, but once one makes that first leap in accepting the reality of an objective extra-mental reality, all of this proceeds by principle and evidence.
