He is best known for his hypothesis about the respective roles of the brain’s two hemispheres and how they work together. This is not a recasting of Roger Sperry’s split-brain theory or the System 1 and System 2 modes of thought introduced by psychologist Daniel Kahneman in his New York Times bestseller, Thinking, Fast and Slow.
Jon Evans How do the left and right hemispheres do things differently?
Iain McGilchrist If you want a very simple, single point, it’s that the left hemisphere produces a representation of reality, whereas the right hemisphere actually puts us in touch with the presence of reality. We’re so used to representation that we can’t see how very different it is. Almost everything that we live in now is a representation, a projection on a screen in two dimensions; living in a city which represents certain things but nature is absent from it. So it’s like the difference between a diagram, a theory, a map, and the actual territory of the real world — or the terrain as I prefer to say — in which we live. And the map is very much simpler than the terrain. And that’s not a criticism, because we need simplicity for a map to work. If it had too much information in it, it wouldn’t work. But it’s vital not to mistake the map for the real world.

1. This conversation demonstrates that the company name is not a reflection of the System 1 and System 2 modes of thinking presented in the book Thinking, Fast and Slow.
In his book Tales of Power, Carlos Castaneda’s teacher don Juan Matus explains the difference between the tonal (first attention — correlates with mundane world) and the nagual (second attention — correlates with primal world), making pretty much the same distinctions that Iain McGilchrist makes in the quoted passage. You can read more here: What Newcreators call mundane world and primal world, don Juan Matus calls the tonal and the nagual.
How McGilchrist’s left and right correlates with the Newcreator’s left and right
McGilchrist’s understanding of the role of the brain’s right hemisphere correlates with primal world (the nagual, second attention), the seat of creative imagination where we foresee possibilities for enriching the world with value, meaning and joy.
His understanding of the role of the left hemisphere correlates with mundane world (the tonal, first attention), the place where synthetic imagination occurs, enabling us to do the practical work of turning embryonic ideas into robust concepts, bringing them to life and fully realising their value generation potential.

Books
The Master and His Emissary: The Divided Brain and the Making of the Western World
“The Master and His Emissary: The Divided Brain and the Making of the Western World is a 2009 book written by psychiatrist Iain McGilchrist that deals with the specialist hemispheric functioning of the brain. The differing world views of the right and left brain (the “Master” and “Emissary” in the title, respectively) have, according to the author, shaped Western culture since the time of the ancient Greek philosopher Plato, and the growing conflict between these views has implications for the way the modern world is changing In part, McGilchrist’s book, which is the product of twenty years of research, reviews the evidence of previous related research and theories, and based on this and cultural evidence, the author arrives at his own conclusions.” Wikipedia

“In The Matter With Things, Iain McGilchrist tackles the big questions: Who are we? What is the world? How can we understand consciousness, matter, space and time? What happens if we neglect the sacred and divine? He argues that we have become enslaved to an account of things dominated by a partial view dominated by the brain’s left hemisphere, one that blinds us to an awe-inspiring reality that is all around us, had we but eyes to see it. He suggests that in order to understand ourselves and the world we need science and intuition, reason and imagination, not just one or two. When we do, we tap into an understanding that is both profound and beautiful, in line with the deepest traditions of human wisdom. Dr. Iain McGilchrist is a psychiatrist, philosopher and literary scholar. He is a Quondam Fellow of All Souls College, Oxford, a Fellow of the Royal College of Psychiatrists and of the Royal Society of Arts, as well as a former Clinical Director of the Bethlem Royal & Maudsley Hospital, London. With a gift for synthesising neuroscience, culture and philosophy, his thought has provided essential frames for making sense of the times we live in and proved particularly influential on Rebel Wisdom over the years.” David Fuller, co-founder of Rebel Wisdom (now closed)
