Challenging Notions: Consciousness and the Concept of Self

In the realm of consciousness, a prevailing belief since Descartes' time has been that consciousness is inseparable from a defined self. However, neuroscientist and author James Cooke proposes a thought-provoking alternate view—one that questions the necessity of a self for consciousness.

Often, we perceive ourselves as the conscious subject, directing attention to objects, seemingly behind our eyes, in our heads. This intuitive mental model has strongly influenced our understanding of consciousness. However, Cooke challenges this paradigm, suggesting that consciousness is fundamentally a quality of the bodily subject, rather than the perceived conscious subject residing in our minds.

Descartes' theory, a foundational aspect of scientific thought, speculated that only humans possessed consciousness, requiring a transcendent subject to explain the world. However, this notion led to an infinite circle of explanations without truly unraveling the essence of consciousness—the so-called "Cartesian Theatre."

Neuroscientific perspectives on consciousness imply the existence of a self-like mechanism in the brain responsible for conferring awareness. The brain, operating through hierarchical structures, processes sensory data, with higher levels handling cognitive functions like attention and decision-making. Theories on consciousness—bottom-up and top-down—find support in neural correlates across various brain areas.

Moreover, experiments challenging the introspecting subject's role in consciousness reveal intriguing aspects. Studies utilizing physiological indicators suggest that brain mechanisms linked with introspection do not contribute to consciousness but merely report its contents.

Beyond neuroscience, phenomenological analysis delves deeper, showcasing instances where consciousness exists independently of a psychological self. Instances involving psychedelics or meditation often induce a state where consciousness persists, but the psychological self dissipates.

Cooke emphasizes that consciousness is not the attribute of an experiencing subject but a formless awareness where experiences arise. This stance echoes Immanuel Kant's idea that humans perceive a subjective reality rather than an objective truth.

Additionally, concepts from Bayesian inference suggest that belief updating, a fundamental aspect of survival, transcends brains. The Free Energy Principle posits that any system maintaining order requires a process akin to Bayesian inference.

Ultimately, Cooke's propositions challenge the prevalent belief that consciousness relies solely on sophisticated cognitive machinery or the presence of a defined self. Instead, he prompts us to consider consciousness as an innate, pervasive quality, shared across all life forms, surpassing the confines of complex brains and introspective selves.
