@fresco,
Quote:The frog data is empirical from a social agreement point of view.. Comparative physiology equally indicates that bird's vision differs from that of humans in terms of the dimensionality of their color perception apparatus. And, fish sense their neighbours through electric field disturbances with which we have great difficulty communing. What other extrapolation makes sense other than "reality is species specific" ? Add to that cultural "perceptual set" for humans and we can understand why in early Christian times the rainbow was seen to factually contain 4 colors in accordance with the four gospels. For all we know, birds might have been aware of 23 colors, and rainbows are unlikely to be part of a fish's reality !
If the "village lad" of an elderly couple entered a scientific laboratory, he'd have few concepts and terms for discerning, identifying, and understanding what he was perceiving. Perhaps resorting to generalizations equivalent to "meaningless junk" or "roomful of curious, unknown objects". Now granted, his problem does stem from not having acquired many conceptions as well as object-specific terms and their definitions from the conventions of a social community. In this particular instance, that of scientists and the specific discipline the lab concerns. His nominal "reality" therefore, in the "reflective thought" or understanding vein (distinguished from his sense reality discussed below), is not the same as the scientists' -- or is vastly less detailed / complex, also missing their guiding biases / methods.
But "the Lad's" incapacity or lack of interest in discriminating language-wise most of the lab background into specific things (even as "incorrect" speculative interpretations and meanings applied to them) does not mean his raw perceptions are minus their own automatic, "before reflective thought" scheme for breaking that environment down into interconnected, individual phenomena. (Or in Kant's case, also providing the very environment itself by spatiotemporal structuring of received data). The latter appearances are therefore already available for inspection by the focused interest or cognitive attention of the Lad, should he overcome the indolent tendencies of his intellect.
The Lad's sensible "reality" (the one manifested in external experience) should for the most part have intersubjective agreement with the rest of humanity -- that is, his perceptual system is regulated by general principles that are "distributed universally" (for lack of better way to put it) to most humans that are free of "defects" or non-trivial clinical conditions. This prior-to-intepretation "external world" deriving its objectivity from its interpersonal accessibility and likewise global reliability (conforming to predictable or rule-abiding expectations in the manner it is presented / occurs).
Whereas the planet Mercury or lesser types of "rocks" would exhibit no brand of reality whatsoever for themselves. Even Leibniz's panpsychism would hold that their "perceptions" are confused because their corresponding (noumenal) monads lack the logical equipment for disambiguating distinct phenomena from a "blurred" or condensed condition. Kant would just hold that they'd lack any proto-appearance because Leibniz eliminated a sensible faculty for organizing "noise" into structural patterns, speciously prior to application of the Understanding, even in regard to advanced rational beings like humans.
Accordingly, animals (frogs, fish, birds) are somewhere between that "no world at all" status for non-brained entities and that of humans, when it comes to the environment they "drape" themselves in via their sensory and interpretation schemes. When the scientists tries to conceive "what it is like to be bat", however, it is the context of what falls out of research into his/her natural conception of cosmos, and its subset of biological affairs. The bloody bat, in itself, may lack any interest of explaining and generalizing "what's going on" beyond its immediate life as a "reality" (or that there is a beyond to bat-life). And even if it did, it would probably be more akin to the jumbled, mystical, dream-like outlook of existence that pre-scientific human cultures had, not the philosopher's and the scientist's fixations with interconsistency.
