In the first part of your book, you speak about the seven portals to knowledge. How would you how would you encourage a reader or listener to think about those? Well, what i wantyed to do as to look separately at the level at which we gain information about the world from and even some knowledge of it. And that might be things like science and reason and intuition and imagination,. Which form part two of my book. One is about the immediate things that the brain is able to do when it's observing the world. But attention is very, very important to me, because i realize that attention changes the world. It founds the nature of the only world we can experience.
