An evidence-based critical review of the mind-brain identity theory

Abstract

In the philosophy of mind, neuroscience, and psychology, the causal relationship between phenomenal consciousness, mentation, and brain states has always been a matter of debate. On the one hand, material monism posits consciousness and mind as pure brain epiphenomena. One of its most stringent lines of reasoning relies on a ‘loss-of-function lesion premise,’ according to which, since brain lesions and neurochemical modifications lead to cognitive impairment and/or altered states of consciousness, there is no reason to doubt the mind-brain identity. On the other hand, dualism or idealism (in one form or another) regard consciousness and mind as something other than the sole product of cerebral activity pointing at the ineffable, undefinable, and seemingly unphysical nature of our subjective qualitative experiences and its related mental dimension. Here, several neuroscientific findings are reviewed that question the idea that posits phenomenal experience as an emergent property of brain activity, and argue that the premise of material monism is based on a logical correlation-causation fallacy. While these (mostly ignored) findings, if considered separately from each other, could, in principle, be recast into a physicalist paradigm, once viewed from an integral perspective, they substantiate equally well an ontology that posits mind and consciousness as a primal phenomenon.

UPDATE: Below is a comment from a reader. I am reposting it closer to the article it refers to because it greatly widens the discussion of what consciousness is and how to understand it. ABN

Please allow me to point out a clear oversight in this abstract. This abstract implicitly suggests that if one rejects material monism, they must subscribe to either dualism or idealism. This binary framing excludes other philosophical perspectives such as Radical Empiricism (R.E.) that do not fit neatly into these categories, which prioritize substance (whether mental or physical) over pure experience.

As proposed by William James, Radical Empiricism offers a distinct alternative that is neither strictly materialistic nor dualistic/idealistic. It posits that consciousness and experience are integral and interconnected aspects of reality. It’s core tenets embrace two assertions which fundamentally align with Buddhist aggregate theory: (1) the primary substance of reality is pure experience, which includes both the subjective and objective aspects of reality without privileging one over the other. (2) Experiences are fundamentally interconnected and relational.

In R.E., consciousness is not an independent fundamental substance (as in idealism) nor merely an epiphenomenon of the brain (as in material monism). Instead, consciousness is a function of the elements of pure experience, which are continuous and interwoven.

Other non-dualistic and non-materialistic perspectives, such as process philosophy and phenomenology, also challenge this simplistic binary framing.

However, R.E. is the most explicit in asserting elements of pure experience as more ontologically fundamental than either the mental or physical worlds of experience, which are seen to be mere abstractions from pure experience.

In Radical Empiricism, consciousness is not the fundamental substance of reality but a manifestation of the dynamic interplay of experiences. This view avoids the pitfalls of both dualism and material monism by grounding consciousness in the relational fabric of pure experience.

What I wish to emphasize in this commentary is that consciousness, while central to understanding human experience, is not an isolated phenomenon but intricately linked with the flow of experiences.

The abstract’s presupposition that rejecting material monism necessitates adopting dualism or idealism is a form of a false dilemma, which is a logical fallacy. By not considering other viable philosophical approaches, it limits the scope of the discussion and potentially misleads readers about the diversity of thought in the philosophy of mind.

Thus, an integral perspective stemming from a more holistic approach (such as the chain of interdependent originations in Buddhist aggregate theory) aligns well with Radical Empiricism by considering the interconnectedness and relational nature of experiences. This is the justification for explicitly asserting such discussions, as this abstract invokes, must include R.E. as a valid and valuable approach to understanding consciousness.

Radical Empiricism’s emphasis on direct experience and empirical grounding aligns with the empirical findings in neuroscience that challenge simplistic materialist explanations. Highlighting this alignment is important in order to show how and in what manner R.E. can bridge empirical data and philosophical insights.

In conclusion: The abstract’s oversight in presenting a false dichotomy between material monism and dualism/idealism is a significant limitation. Radical Empiricism provides a nuanced and comprehensive alternative that views consciousness as a function of the elements of pure experience, rather than as a separate fundamental entity. A more inclusive and accurate discussion would acknowledge this and other philosophical perspectives, enriching the debate and providing a more robust framework for understanding the nature of consciousness.

    1. Terrific reply, thanks. I’ve taken the liberty of reposting your comment on the front page under the article so more people we see it. Hope that’s OK with you.
