What a self is.

Reading Michael Pollan’s account of his meeting with Anil Seth in his recent book "A World Appears" has prompted me to write down for my own use what I take a “self” to be. This post archives that summary and shares it with interested MindBlog readers.

So, here’s the summary:*

The self can be understood, to use Seth's phrase,  as a "controlled hallucination." Our brains build this construct to regulate the body using interoceptive signals—internal data about our heart rate, breathing, and chemistry—to maintain stability (homeostasis) in the face of constant disruption. From these signals arise feelings and emotions that drive us to act, biasing behavior toward preserving coherence and pushing back against the entropy that would otherwise dissolve it. Our illusion of having agency, of being able to do things that matter, is one of our most necessary and powerful emotions.

This hallucination is not just about the present moment. It stitches together a historical self from memory and prior experience (the brain’s ‘priors”), then projects that self forward in time, generating a predicted future to act into. We are, in this sense, always living slightly ahead of ourselves. The self is not a fixed entity but an ongoing process: a predictive framework that links memory, expectation, and action.

The self is also a stage — a theater or structural model that evolved to support the regulation of the neuroendocrine machinery underlying our social emotions and feelings such as fear, status, and affiliation - feelings that tie us to others and to our place in the world.  The theater of selfhood enables these processes to operate coherently across time and context.

And here is what I find most striking: once this elaborate scaffolding is in place, it sometimes becomes possible to step outside of it. To temporarily set aside the past and future timeline, the narrative, the predictions — and let awareness rest in the present moment alone. In that open, unhurried awareness, thoughts, feelings, and actions can be observed as they arise, like wisps of vapor emerging from some deeper source.

The self, it turns out, may be most clearly seen from just outside it.

*A note on how I arrived at the above text:    I wrote a paragraph of my ideas, and then presented the prompt “Please do an edit or redraft of this MindBlog post draft to make it more comprehensible to readers:” to four LLMs (ChatGPT, Gemini, Claude, and DeepSeek.) I then curated the four versions to select useful improvements of my text and did further editing myself to make the final product.
