The title of this book is from a quote from Being You by Anil Seth: “I open my eyes and a world appears.” It is an inquiry into what human consciousness really is. Pollan starts from a perspective of ignorance and interviews expert after expert, each with their own perspective on the subject. It is not as easy reading, for me at least, as other Pollan books I have eagerly devoured, such as How to Change Your Mind, in which Pollan delves deeply into psychedelic experiences; This Is Your Mind on Plants, which in a way is a continuance of How to Change Your Mind; and A Place of My Own, which is a memoir about how Pollan built himself a writer’s retreat in his backyard. Part of the difficulty I had with A World Appears is that it deals with abstractions; there are no easy answers, and Pollan is trying to figure things out as he goes along. He explains that “there is no godlike vantage from which we can objectively regard consciousness, because all views, including neuroscience’s and philosophy’s, are themselves the products of consciousness.”
The book is broken up into various sections with chapter titles such as “Sentience,” “Feeling,” “Thought,” and “Self.” In each of these, Pollan explores ideas based on recent studies. In the chapter on sentience, he investigates the possibility of sentient plants. One problem about exploring topics such as this is that “scientists bring their particular human-scale perspective to other life-forms and, as a result, miss all sorts of other kinds of intelligence.” A philosopher named Evan Thompson explains that “we have lost our empathetic resonance with the larger universe.” He believes that indigenous cultures, with their more participatory approach, may hold the key. And Pollan emphasizes that “a new science of consciousness will likely be a hybrid enterprise,” which will include not only empiricism and experimentation, but also philosophy, imagination, the arts, spiritual traditions, personal experience, and altered states of consciousness such as those derived from psychedelics.
In the section on feelings, Pollan explores the issue of artificial intelligence and whether AI can truly be conscious (Pollan tends to think maybe not). He investigates the research of a team of scientists trying to construct a robot with feelings, but also delves into the ethical considerations of such an enterprise. He says: “We can only hope that the profit motive doesn’t outrun the public good, but if our experience with the last big digital innovation – social networks – is any guide, it probably will.” He points out the differences between brains and computers – which are vast – and that animal life forms such as humans (as opposed to AI) have the advantages of their bodies, which contribute greatly to feeling and consciousness. “The vulnerabilities of our mortal flesh” actually give us great advantages over “the consciousness they’re hoping to install in computers.”
The section on thought includes analyses of stream-of-consciousness attempts by famous novelists and also of the value of spontaneous thought, which leads to inspiration. In the section on self he emphasizes the importance of memory.
Pollan comes to no definitive conclusions. He writes: “Nearing the end of this journey, I find myself not at all sure what to believe, if anything.” In fact, in the last chapter he travels to a Buddhist retreat in the mountains near Santa Fe. The goal? The obliteration of self. It is a temporary fix, of course, because once he leaves the retreat, he is again confronted by the world he left behind.
As I mentioned earlier, parts of this book I found to be tough going. Navigating the many theories and possibilities that are presented can be confusing. One anchor to it all is Pollan’s skepticism. He doesn’t pretend to have the answers; he is content to take us on a journey to explore the possibilities. He functions as a tour guide, leading us from one researcher to the next, asking questions and presenting a range of speculations, inferences, and presumptions. I don’t know if I would recommend this book to everyone, but if you are interested in such heady topics, Pollan takes you on a pilgrimage of the mind that you won’t soon forget.
