Recent findings in cognitive science have provided profound empirical support for a subjective interpretation of consciousness, which aligns closely with the ideas rooted in Husserl’s phenomenology and the applications of generalized agent theory. By understanding the brain as a network of interacting agents, each contributing to the experience of “now,” we can explore how different levels of consciousness operate in an interconnected web, from individual neurons to the entire conscious self. This paper will unpack these new findings, showing how they provide evidence for the subjective emphasis that underpins both phenomenology and agent theory.
The brain can be conceptualized as a network composed of numerous agents, each participating in a dynamic bubble of now. These agents range in scale, from entire regions that govern higher-order processing to individual neurons that play essential roles in information transmission and computation. In this framework, each neuron can be seen as an agent that perceives, integrates, and acts upon information—a micro-level Perception-Integration-Action (PIA) cycle similar to that of larger cognitive processes.
The Penrose-Hameroff model, which hypothesizes that microtubules within neurons might be key sites for quantum processes related to consciousness, is particularly relevant in this context. This model suggests that individual neurons may have their own form of proto-consciousness, contributing to the holistic experience of awareness that arises at the macro level. This aligns with the generalized agent theory by proposing that the subjective experience of consciousness emerges from multiple agents acting in concert, each participating in its own cycle of perception, integration, and action within the broader field of agency.
To understand how this subjective, agent-based model relates to human consciousness, it is crucial to look at recent empirical studies that have explored the neural basis of language, consciousness, and identity. These findings reveal that different facets of our experience—including language processing, self-awareness, and motor control—are localized in distinct brain regions, which function semi-independently but in coordination with one another.
Research conducted at institutions like MIT and Harvard, using functional magnetic resonance imaging (fMRI), has revealed that the neural mechanisms for language processing and conscious awareness are distributed across different parts of the brain. Language, for instance, is primarily processed in areas like Broca’s and Wernicke’s areas, which are largely localized to the left hemisphere of the brain. These regions are responsible for generating and comprehending speech but are only part of the broader conscious experience.
In contrast, conscious awareness itself involves more extensive networks that integrate multiple sensory modalities and are distributed throughout the brain, including the prefrontal cortex and the extrastriate cortex. These findings suggest that what we commonly refer to as “thinking” or “being aware” does not depend on a singular brain region but rather emerges from the interaction of various neural processes. The distinction between the areas of the brain involved in language and those responsible for self-awareness underscores the complex, layered nature of consciousness—a central tenet of phenomenology, which argues that consciousness is fundamentally subjective and multi-faceted.
fMRI studies often use task-based approaches, where subjects perform specific activities (e.g., language comprehension or motor tasks) while brain activity is recorded. These studies have shown that neurons in regions responsible for language, such as the left temporal lobe, activate differently compared to neurons involved in maintaining a sense of self or present-moment awareness, which are located in the medial prefrontal cortex and the temporoparietal junction. This separation of functions supports the idea that consciousness is composed of multiple overlapping yet distinct fields of agency, each contributing to the unified experience of “now.”
Another significant empirical finding involves the discovery of different temporal windows in language processing. Studies have shown that different neural clusters process language at different timescales—some neurons integrate information over single words, while others work over phrases of up to six words. This temporal integration aligns with the idea that meaning unfolds over time, and it suggests that consciousness itself has a temporal architecture, with different neural agents contributing to our understanding of language and context across various timeframes.
The implication for agent theory is that each neuron, or cluster of neurons, can be seen as an agent operating within its own temporal window, contributing to the broader, dynamic process of meaning-making. This supports a phenomenological perspective, where the present moment (or “bubble of now”) is not static but is instead a constantly evolving field of awareness, shaped by both the immediate past and anticipated future.
The distinction between language processing and general consciousness also leads to interesting insights into the nature of narrative and meaning. The language centers in the brain can be thought of as a “text engine”—a specialized field of agency that operates independently of the direct sensory experience of the corporeal world. Unlike vision or touch, which are grounded in the immediate physical environment, the text engine allows for an interaction with abstract symbols that represent events, thoughts, and experiences across time.
The ability to generate, interpret, and internalize narratives gives humans a unique cognitive capacity: the ability to transcend the present moment and engage with past and future experiences as if they were happening “now.” This creates a novel layer of consciousness, where language becomes a tool for preserving the past and constructing the future. Neuroimaging studies have shown that reading and understanding text involves activation in brain areas that are distinct from those responsible for sensory processing, further supporting the idea that narrative operates in its own field of agency.
The text engine provides a way for individuals to construct a coherent sense of identity over time. By engaging with narratives, we are able to build and maintain a consistent self-concept, integrating memories of past events with projections of future goals. This aligns with Husserl’s idea of the temporal structure of consciousness, where every present moment carries within it both the retention of past experiences and the protention of future possibilities.
The phenomenology of the “bubble of now” describes the way in which consciousness is experienced as a seamless flow, despite being composed of discrete neural events. In agent theory, this bubble can be understood as the dynamic interplay of countless agents—neurons, neural networks, brain regions—each contributing to the present moment. Each agent operates within its own PIA cycle, perceiving incoming signals, integrating them based on past experience, and acting to influence future states.
The Penrose-Hameroff model adds an interesting dimension to this understanding by suggesting that quantum processes within neurons may play a role in binding these discrete events into a unified experience. This suggests that there is an element of consciousness that goes beyond classical computation, adding a “trans-quantum” layer to the subjective experience of the present moment. The subjective now, therefore, is not merely the sum of neural firings but is also shaped by deeper processes that may involve quantum-level interactions, providing an even richer basis for understanding the uniqueness of conscious experience.
The bubble of now is, thus, both timeless and temporal. It is timeless in the sense that the present moment is always “now,” yet it is temporal because it carries the traces of the past and anticipates the future. Each agent’s perception of the present is influenced by its history of interactions and its expectations for what comes next, creating a continuity of experience that cannot be fully reduced to a single point in time or space.
The integration of recent empirical findings from cognitive science with generalized agent theory and phenomenology reveals a deeply subjective nature of consciousness. The brain can be viewed as a vast field of agents, each contributing to the holistic experience of the present moment. From individual neurons operating as agents with their own PIA cycles to entire brain regions specializing in language, self-awareness, or sensory processing, consciousness emerges from the coordination of multiple interacting systems.
The distinction between language and other sensory experiences highlights the unique nature of the text engine as a separate field of agency. This facility allows humans to transcend the immediate physical world and interact with abstract symbols that preserve the past and shape the future. By viewing the brain as a collection of interacting agents, we can better understand how consciousness arises from both the sum of its parts and the dynamic interactions between them.
Ultimately, the subjective nature of consciousness, as described by Husserl and expanded upon through agent theory, is supported by the latest findings in cognitive science. The bubble of now is a rich, multi-layered experience shaped by countless agents, each participating in the ongoing creation of meaning and awareness. This understanding not only aligns with phenomenological insights but also provides a new framework for understanding the complexity of human consciousness in empirical terms.
