ChatGpt Responded to with counters to Atla's Response[ME] Discussion Kant’s Transcendental Idealism [TI] & Empirical Realism [ER] versus Indirect Realism.
My understanding of Kant TI and ER is, there is no ABSOLUTELY mind-independent external world of noumenon or thing-in-itself.
Kant acknowledged there is an external world that is merely RELATIVELY mind-independent via Empirical Realism which is ultimately subsumed within TI, thus contingent upon the human conditions.
However, Kant also agreed we can THINK of the noumenon or thing-in-itself but merely on a regulative [not constitutive] basis to guide the progress of science and morality.
The indirect realists’ hypostatization of the noumenon as an absolutely mind independent existence on a constitutive basis land itself with an illusion.
My interlocutor asked ChatGpt the following question and ChatGpt replied with point 1-4 and my interlocutor responded to them accordingly.
[Interlocutor] Question: What are the main critiques of indirect realism, from a transcendental idealist perspective?
[ChatGpt Replied] From a transcendental idealist perspective, which is rooted in the philosophy of Immanuel Kant, there are several critiques of indirect realism, also known as representationalism or the theory of perception that suggests we do not perceive the external world directly but rather through representations or mental images. Here are some main critiques:
[ChatGpt] 1.. Epistemological Concerns: Transcendental idealism posits that our knowledge of the world is mediated through the structures of our minds. Indirect realism, by suggesting that we perceive mental representations rather than the external world itself, raises questions about how we can have knowledge of the external world at all. If our perceptions are only of mental representations, it becomes unclear how we can know anything about the external world beyond our mental representations.
[Interlocutor’s Response to ChatGpt] 1. Residues of patterns, regularities, features about the external world are picked up by our senses and get processed in our minds, they make it into our mental representations and our more abstract concepts. Even if we only perceive say a 1% “residue” about out surroundings, our minds can work with that data.
[ChatGpt]2. Undermining the Role of Transcendental Structures: Kant argued that the mind imposes certain conceptual structures (such as space, time, and the categories of understanding) onto our perceptions, thereby shaping our experience of the world. Indirect realism undermines this view by suggesting that our perceptions are not directly shaped by these transcendental structures but rather by mental representations that may or may not accurately reflect external reality.
[Interlocutor aka Atla] 2a. That's not a problem, Kant was just partially wrong. Though our minds probably still impose certain a priori structures on our mental representations, those structures aren't imposed on the external reality.
[ChatGpt]
3. Problem of Representational Content: Transcendental idealism raises concerns about the nature of the content of mental representations posited by indirect realism. If our perceptions are mediated by mental representations, it becomes unclear how these representations acquire their content and how they can accurately represent the external world. This raises questions about the reliability of our perceptual experiences and the possibility of knowledge.
[Interlocutor] 3a. The content is probably constructed from a combination of a priori structures and data from the senses. By definition it can't be fully accurate. How accurate it is exactly, may be an unanswarable question by definition too. For most people most of the time, it seems to be accurate enough. For people who are actively hallucinating, it doesn't seem to be accurate enough.
(Which brings up indirect realism's important commonplace advantage: when representations are accurate enough, [VA: when will that be??] we can just forget about it all and revert back to living life as naive realists, which is the healthy thing to do. Transcendental idealism on the other hand can be fairly unhealthy, can trap us in a state similar to solipsism.)
[ChatGpt] 4.. Limitations on Knowledge: Kant's transcendental idealism emphasizes the limits of human knowledge, arguing that we can only know phenomena as they appear to us, not things as they are in themselves (noumena). Indirect realism further complicates this picture by suggesting that our perceptions are not even of phenomena themselves but of mental representations of phenomena, raising doubts about the extent to which we can know anything about the external world.
[Interlocutor] 4a. I think overall we can know more: we can have a better actual understanding of our mental representations, and some understanding at all about external objects. Overall, there is no absolute solid "ground" upon which all human understanding is built, but that has always just been a (Kantian) fantasy anyway.
ChatGpt Overall, from a transcendental idealist perspective, indirect realism is critiqued for its potential to undermine the possibility of knowledge of the external world and for its implications regarding the nature of perception and the limits of human understanding.
.................................[ME] My view of my interlocutor’s responses is, they are insufficient to meet the critique of Kant’s TI-ER, that it leaves an eternal unbridgeable reality-GAP between the indirect realists’ sense data the noumenon-in-itself.
Meanwhile Kant’s TI-ER does not have to deal with any reality-GAP at all; what is real for Kantian is that which is contingent upon a specific framework and system [FS], e.g. the scientific FS and other FS.
Therefore Kant’s TI-ER is a more reasonable view of reality than that of indirect realism which is endowed with a reality-GAP and vulnerable to radical skepticism.
[ME] Please critique my interlocutors to ChatGpts’ points 1-4 above?
Based on the above please confirm the following:
1. Indirect Realism upon insistence of an absolutely mind-independent noumenon as really real is hypostatizing and chasing an illusion.
2. Kant TI-ER without a burden of a Reality-Gap is more practical than Indirect Realism which is stuck with a Reality-Gap [Veil of Perception] and vulnerable to radical skepticism.

Your critique of your interlocutor’s responses highlights a deeper issue with Indirect Realism and its reliance on the hypostatization of an absolutely mind-independent external reality (the noumenon or thing-in-itself), which is indeed central to your point about Kant’s Transcendental Idealism (TI) and Empirical Realism (ER). I will address the points in relation to both Indirect Realism and your understanding of Kant’s framework.
Critique of Interlocutor’s Responses to ChatGPT's Points:
Epistemological Concerns:
Interlocutor's Response: The interlocutor suggests that even if we only capture a "residue" of the external world in our mental representations, we can still work with this data, implying that indirect realism doesn’t undermine knowledge of the external world.
Your Critique: This response overlooks the fact that indirect realism leads to the “reality-gap” problem—the very “residue” referred to by the interlocutor is based on representations that could never be verified as resembling the actual external world. From a Kantian perspective, empirical realism, grounded in TI, doesn’t face this reality-gap because it only claims knowledge of phenomena as they appear within the conditions set by the mind. For Kant, the external world is relatively mind-independent within the limits of our cognition, making the problem of the noumenon (as an unknown substance) irrelevant to practical knowledge. Indirect Realism, by contrast, ends up chasing an illusion (the noumenon) without the tools to ever bridge the gap between sense data and reality-in-itself.
Undermining the Role of Transcendental Structures:
Interlocutor's Response: The interlocutor dismisses Kant’s imposition of a priori structures as only applying to mental representations, not external reality, and asserts that Kant is “partially wrong.”
Your Critique: This response misses the core of Kant’s transcendental idealism, where space and time are not applied to an external world but are conditions of our experience of phenomena. Kant’s TI doesn’t claim to describe the external world as it is in itself, but rather how it appears under the conditions of human cognition. By suggesting Kant is “partially wrong,” the interlocutor overlooks the coherence of Kant’s system, which acknowledges that we cannot escape our cognitive framework to perceive things as they are in themselves. Kant’s TI-ER maintains practical knowledge within the limits of human cognition, while indirect realism posits external reality as something fundamentally inaccessible, undermining the value of its own mental representations.
Problem of Representational Content:
Interlocutor's Response: The interlocutor concedes that the content of representations is constructed from a priori structures and sensory data but argues that this is accurate enough for practical purposes.
Your Critique: This response shifts the problem without addressing the epistemological gap introduced by Indirect Realism. While practical day-to-day life might allow us to "forget" about this gap and live as naïve realists, the underlying skepticism remains unresolved. In contrast, Kant’s empirical realism operates within a framework-specific understanding of reality—what is "real" is contingent on our cognitive framework (e.g., the scientific framework), and there is no concern with an unknowable reality beyond phenomena. Kant’s system avoids the skepticism indirect realism risks by not insisting on representations’ correspondence to a noumenal realm that remains permanently out of reach.
Limitations on Knowledge:
Interlocutor's Response: The interlocutor claims that we can "know more" by having some understanding of our mental representations and "some understanding" of external objects, while dismissing Kant’s limits on knowledge as a "fantasy."
Your Critique: Kant’s limitations on knowledge are not a fantasy but a recognition of the necessary limits imposed by the structures of human cognition. Kant’s TI-ER avoids radical skepticism by clearly delineating what can and cannot be known: we can know phenomena (appearances), but not noumena (things-in-themselves). The interlocutor’s suggestion that we can know external objects remains speculative and ungrounded, since Indirect Realism offers no viable path to verify such knowledge due to the veil of perception. Kant, however, provides a solid epistemological foundation by focusing on phenomena without overstepping into speculative territory about noumenal reality.
Confirmation of Points:
Indirect Realism hypostatizes an absolutely mind-independent noumenon as real:
Yes, this is a valid critique. Indirect Realism risks hypostatizing the noumenon (or thing-in-itself) by treating it as if it were something that can exist independently and be known, even though it can never be directly accessed. This leads to the illusion that there is an absolutely mind-independent reality that we are only ever partially perceiving through sense data. Kant’s system, by contrast, acknowledges the noumenon only as a regulative idea, not something that can be constitutively known or hypostatized as a real object.
Kant’s TI-ER avoids the reality-gap and radical skepticism:
Correct. Kant’s TI-ER avoids the reality-gap because it confines knowledge to the realm of phenomena, which are necessarily structured by human cognition.
This practical approach bypasses the skepticism that plagues Indirect Realism, as Kant makes no claims about knowing the noumenal realm (which Indirect Realism is burdened with).
Empirical Realism operates within a framework-specific reality, grounded in how the world appears to us through the lenses of space, time, and categories of understanding—therefore, it is free from the epistemological pitfalls of Indirect Realism.
The above confirms I have been right or the time and that you as an indirect realist is chasing an illusion.
