A world appears: A journey into consciousness - book overview

A catch up on aspects of neuroscience, especially to inform thoughts on AI of General AI (GAI) being able to take on human consciousness. Update on readings about a decade ago including Soul Dust; Sentience; the problem of soul; Who am I? and Tell-tale brain. 

Borrowed the book - A world appears: A journey into consciousness - by Michael Pollan from the local library, published 2026 by Penguin.

I have read several of Pollan's book, due to my interest in food. His many books provide alternatives ways to view often mundane topics. He writes for the layperson, but his work draws on the corpus of literature (albeit predominantly from the Western thought canon) and interprets perspectives that connect well with everyday life.

This book is again an accessible introduction to the difficult topic of consciousness. The book brings contemporary research along with an overview of efforts in the past to understand the topic. Pollan talks to many of the researchers in the field, providing a sense of their work and interpreting how each way of understanding the difficult concept of consciousness, adds to an understanding of what might be, what might not be and the many aspects of its amorphous nature.

It is a relatively short book. The introductory chapter lays out the direction of the book. Then follows 4 interwoven chapters, sentience, feeling, thought and self. Each begins with an attempt to define the main topic and then undertakes a discussion around the many themes and variations that underpin the topic. The last chapter 'the cave' is in introspective conclusion on the many rabbit holes and directions the previous chapters traverse.

Pollan himself undertakes to be a 'test subject' in several of the projects he investigates. In previous books, he has written about his use of hallucinogens, as a way to explore alternative realities. The book wanders through the many options availed to try to understand consciousness. In short, there is no agreement or rational statement that defines consciousness. We need to be very cautious about accepting statements on 'AI attaining consciousness' when it is so difficult to pin down consciousness itself. Organic perspectives, including thinking, feeling, sensing etc. and how these contribute towards a sense of 'self' must always be carefully navigated and thought through as non-organic representations likely only 'capture' a hint of what it means to have consciousness. 

There are copious notes across the book. I will need to check out the Journal of Consciousness Studies which publishes interdisciplinary work on consciousness and several recent books.

Onwards to more reading and learning :)
