Books in the humanities often begin with a statement of the author’s position. Science books rarely do. Since this book involves as much philosophy as science, let me start by describing where I am coming from. I have a long-standing dislike of mystical or magical thinking in all its forms. A dislike of thinking that avoids rigorously seeking a good explanation and opts instead for an attractive one. Of thinking that settles for a baroque explanation rather than accepting that some things are as yet unexplained. The usual suspects of free will and consciousness are fertile ground for such thinking, as is emergence, a term widely used to describe complex systems and a central topic of this book. This means I am an opinionated narrator. But I strive to be a reliable one and include extensive references and suggestions for further reading to help you make up your own mind. Let me give an example of what motivates me. Later in the book I will cite a philosopher of science who argues that the placebo effect is evidence against physical causal closure. I find this deeply suspicious. Causal closure is right down at the fundamental level of quantum physics. The placebo effect, while well documented, is a property of the human brain, the most complex and poorly understood system we’ve come across. No evidence is given which links the two. Perhaps the philosopher will turn out to be right. But for now there is no reason to think that our lack of understanding of the brain should have any implications for physics. Descriptions of emergent phenomena often convey little more than “Wow, that’s so mind-blowingly complex it can’t be just physics”. For those who want to see more clearly, this book shows how emergence can be eliminated and presents an unflinching worldview in which everything, without exception, is physics.
