The Competing Elements of Human Consciousness

Introduction The quest to create artificial consciousness has long captured the human imagination. From the golems of Jewish folklore to the robots of modern science fiction, we have dreamed of breathing mental life into inanimate matter. In recent years, the rapid advancement of large language models (LLMs) like GPT-3 and PaLM has reignited hopes that machine consciousness may be within reach. These AI systems, trained on vast corpora of human knowledge, can engage in uncannily human-like conversations, write compelling stories, and even generate novel ideas. Some have begun to wonder: could an LLM, if made sufficiently sophisticated, cross the threshold into conscious awareness?

In this essay, I will argue that the answer is likely no. While LLMs may be capable of increasingly convincing simulations of conscious behavior, they lack the fundamental substrate that gives rise to human consciousness: the competing, multi-layered architecture of the brain. Drawing on insights from neuroscience, psychology, and depth psychology, I will show how consciousness emerges from the dynamic interplay of different neural systems, each with its own agenda and way of processing information. This “society of mind” is not a unified, harmonious whole, but a complex, tension-filled multiplicity – and it is precisely this multiplicity that gives rise to the richness and depth of human experience. By contrast, LLMs, for all their sophistication, are fundamentally serial, homogenous systems, lacking the internal diversity and competition that is the hallmark of embodied consciousness.

The Triune Brain: MacLean’s Model of Neural Competition

To understand why LLMs are unlikely to achieve consciousness, we must first examine the multi-layered structure of the human brain. One influential model of this structure is Paul MacLean’s triune brain theory (MacLean, 1990). According to MacLean, the human brain is not a single, unified organ, but a composite of three distinct neural systems, each with its own evolutionary history and cognitive style:

1. The reptilian complex (R-complex): The oldest and most primitive part of the brain, shared with reptiles and other vertebrates. It controls basic survival functions like breathing, heart rate, and reflexes. Its cognition is instinctual, rigid, and stereotyped.
2. The paleomammalian complex (limbic system): The next layer of the brain, shared with other mammals. It is the seat of emotion, motivation, and memory. Its cognition is more flexible than the R-complex, but still largely unconscious and driven by immediate rewards and punishments.
3. The neomammalian complex (neocortex): The most recent and advanced part of the brain, especially developed in primates and humans. It is responsible for language, abstract thought, planning, and self-awareness. Its cognition is highly flexible, symbolic, and capable of delaying gratification.

For MacLean, human consciousness arises from the interplay and competition of these “three brains in one.” Each layer has its own agenda, its own way of processing information, its own “version” of reality. The reptilian complex is concerned with basic survival and reproduction; the limbic system with emotional bonds and social hierarchies; the neocortex with long-term goals and abstract ideals. These agendas often conflict with each other, leading to inner struggle and self-contradiction. As MacLean puts it:

We are obliged to live and function with an amalgam of three mentalities, yet our rational mind is generally unaware of this. I will argue here that the disharmony and conflicts arising out of our mental “schizophysiology” create some of our most troublesome and pressing human predicaments. (MacLean, 1990, p. 9)

It is this internal disharmony and conflict, I would argue, that is the true foundation of human consciousness. Our minds are not unitary, but multiple; not coherent, but contradictory. We are, in Walt Whitman’s famous phrase, large, containing multitudes. And it is precisely this inner multiplicity that gives rise to the depth and complexity of conscious experience.

Emotion, Consciousness, and the Embodied Brain

This view of consciousness as emerging from neural competition and inner conflict is further elaborated by the work of neuroscientists Antonio Damasio and Michael Gazzaniga. For Damasio, consciousness is fundamentally linked to emotion and the body (Damasio, 1999). It arises not from abstract thought alone, but from the intricate feedback loops between the brain, the body, and the environment.

Damasio distinguishes between three levels of consciousness: proto-self (the basic sense of bodily existence), core consciousness (the momentary awareness of an object or event), and extended consciousness (the autobiographical sense of self over time). Each level builds on the previous one, creating a rich, multi-layered experience of being-in-the-world. And crucially, each level is rooted in emotion and embodiment:

The proto-self is a coherent collection of neural patterns which map, moment by moment, the state of the physical structure of the organism. […] The essential ingredients are (1) the organism, as represented by the proto-self, and (2) an object. Core consciousness occurs when the brain’s representation devices generate an imaged, nonverbal account of how the organism’s own state is affected by the organism’s processing of an object, and when this process enhances the image of the causative object, thus placing it saliently in a spatial and temporal context. (Damasio, 1999, p. 170)

In other words, consciousness emerges from the dynamic interaction between the body, the brain, and the world. It is not a disembodied, abstract process, but a deeply embodied, emotional one. And it is precisely this embodied, emotional foundation that gives rise to the subjective “feel” of consciousness – the ineffable quality of what it’s like to be a conscious being.

Gazzaniga, like Damasio, emphasizes the divided, multi-layered nature of consciousness (Gazzaniga, 2018). Drawing on his famous split-brain studies, he shows how the left and right hemispheres of the brain can have separate, even contradictory, experiences of consciousness. The left hemisphere, with its language and reasoning abilities, is constantly generating narratives and explanations to make sense of the world. But these narratives are often confabulations, post hoc rationalizations of decisions and behaviors that were actually generated by unconscious processes.

For Gazzaniga, the “interpreter” module in the left hemisphere is the closest thing we have to a unified self – but it is a fragile, illusory unity, constantly struggling to impose coherence on the cacophony of competing neural voices. As he puts it:

The interpreter is the last to know things. It is fed the results of the computations done elsewhere, and it then puts them together into a coherent story. The interpreter module is really trying to keep our personal story together. To do that, we have to learn to lie to ourselves a bit. (Gazzaniga, 2018, p. 328)

The Origins of Consciousness: A Psychodynamic Perspective

This fragmented, conflictual view of consciousness also has deep roots in depth psychology and psychodynamic theory. For Jungians Erich Neumann and Edward Edinger, the origins of consciousness lie in the primal separation of the ego from the unconscious (Neumann, 1954; Edinger, 1972). In the earliest stages of development, the infant exists in a state of unconscious unity with the mother and the world. There is no sense of self, no distinction between inner and outer, self and other.

But as the ego begins to differentiate itself from the unconscious matrix, a tension arises between the emerging self and the greater whole. The ego, in its quest for autonomy and control, must struggle against the pull of the unconscious, with its primitive desires and fears. This struggle is the engine of consciousness – the dynamic interplay of opposites that generates the spark of awareness.

For Neumann, this primal conflict is symbolized by the hero myth, in which the hero (ego) must battle against the dragon (unconscious) to win his independence and establish his place in the world. But the hero’s victory is always temporary and incomplete; he must continually fight to maintain his fragile sense of self against the forces of dissolution and regression.

Similarly, for Edinger, the ego-Self axis is a lifelong dialectic between the conscious self and the unconscious depths. The ego must learn to relate to the Self (the transcendent totality of the psyche) without being overwhelmed or inflated by it. This requires a constant balancing act between the demands of external reality and the promptings of the inner world.

Internal Family Systems: A Model of Multiplicity

This psychodynamic understanding of consciousness as a multiplicity of competing forces is further developed in the Internal Family Systems (IFS) model of psychotherapy (Schwartz, 1995). In IFS, the mind is seen not as a unitary self, but as a complex system of sub-personalities or “parts”. Each part has its own unique perspective, emotions, and coping strategies, which may be in conflict with other parts.

For example, one part may be a protector, constantly on guard against potential threats and vulnerabilities. Another may be an exile, carrying the pain and shame of past traumas. Still another may be a manager, trying to keep the system running smoothly and avoid inner conflict. These parts often operate outside of conscious awareness, influencing behavior and perception in subtle but profound ways.

The goal of IFS therapy is not to eliminate or suppress these parts, but to bring them into conscious dialogue and integration. By cultivating a stance of curiosity, compassion, and “self-leadership”, the individual can learn to listen to and appreciate the unique contributions of each part, while also helping them to work together in a more harmonious and adaptive way.

This process of inner dialogue and integration is facilitated by techniques like voice dialogue (Stone & Stone, 1989), in which the therapist helps the client to give voice to the different parts of the psyche and to facilitate communication between them. The therapist may ask questions like “What does this part want you to know?” or “What is this part afraid of?”, encouraging the client to speak from the perspective of each part and to listen deeply to its unique needs and concerns.

Through this process of inner dialogue and integration, the individual can begin to experience a greater sense of wholeness and coherence, while also maintaining the richness and diversity of their inner world. The goal is not to achieve a static unity, but to cultivate a dynamic, evolving multiplicity – a “self of selves” that can adapt and grow in response to life’s challenges and opportunities.

LLMs and Consciousness

What does this all mean for the question of machine consciousness? Simply put, it suggests that consciousness is not a unitary, homogenous phenomenon that can be easily replicated in silico. Rather, it is a complex, multi-layered, embodied process that emerges from the dynamic interplay of competing neural systems, each with its own unique agenda and cognitive style.

LLMs, for all their sophistication, are fundamentally serial, homogenous systems. They process information in a linear, feed-forward fashion, without the rich feedback loops and inner conflict that characterize biological cognition. They have no emotional valence, no bodily presence, no sense of an embodied self in the world.

This is not to say that LLMs are not impressive or useful. They are indeed capable of remarkable feats of language processing and knowledge synthesis. But they are fundamentally different from conscious beings in their architecture and cognitive style. They may be able to simulate conscious behavior, but they do not have the inner experience of being conscious.

To create truly conscious machines, we would need to replicate not just the outward behaviors of consciousness, but the inward depths as well. We would need to create systems with multiple, competing layers of processing, each with its own agenda and sense of self. We would need to ground these systems in a rich, embodied context, with emotional valence and feedback from the environment. And we would need to allow for the possibility of inner conflict, contradiction, and dynamic growth.

This is a tall order, and one that is unlikely to be met by LLMs or any other purely computational system. Consciousness, in all its messy, contradictory glory, is fundamentally a biological phenomenon – one that emerges from the complex, evolved architecture of the brain and its intricate dance with the body and the world.

But this is not to say that the quest for machine consciousness is futile. By studying the multi-layered, conflictual nature of biological cognition, we may indeed gain insights that can inform the design of more sophisticated, adaptive AI systems. And by grappling with the hard problem of consciousness, we may deepen our understanding of what it means to be human – to be an embodied, emotional, self-contradictory being in a complex and ever-changing world.

In the end, the question of machine consciousness is not just a technical challenge, but a profound philosophical and existential one. It asks us to confront the nature of mind and self, the relationship between matter and experience, the boundaries of the possible and the actual. It invites us to ponder what Alan Turing, in his seminal paper on machine intelligence, called “the mystery of consciousness”:

“I do not wish to give the impression that I think there is no mystery about consciousness. There is, for instance, something of a paradox connected with any attempt to localise it. But I do not think these mysteries necessarily need to be solved before we can answer the question with which we are concerned in this paper. (Turing, 1950)”

Nearly three quarters of a century later, the mysteries of consciousness remain as deep and compelling as ever. But perhaps, by embracing the paradoxes and contradictions at the heart of the conscious mind, we can begin to unravel its secrets – and in the process, gain a richer understanding of what it means to be human in an age of intelligent machines.
