This book fundamendally changed my worldview from a modernist rationalist, where I believed that everything can be calculated via mathematics and eventually controlled by human beings, into someone who believes that the human attempts at order are crude and unsophisticated. The mathematics and intelligence of the natural world is far beyond our capacities of control or even comprehension. Everything affects everything, and human actions are just a drop in the ocean. Yet, the smallest action can sometimes have far-reaching influences. I would call reading this book a sublime experience, i.e. it is an awe-inspiring piece of art. Or rather, the theory behind it is. I read this book some years ago and my intellectual journey since has evolved in a wholly new direction. It has opened my eyes to a completely different set of contemporary and cutting-edge scientists, thinkers and artists, as my own interests and beliefs shifted. When I read it, I sat there for a while and couldn't believe the implications. It was slightly scary as I realised that my world view had been based on a highly simplified version of the real. The potential in such a beautifully organised and complex world is immense. After finishing reading it, the change in my thinking and the consequences then unfolded gradually, over the years.
If you are not familiar with fractal or chaos theory, I recommend this book. It may not have the same effect on you at all but it will at least be interesting. Some mathematical interest will help as the book does discuss some formulas. But you could even skip those pages. I think everyone in the world would in some way benefit from a basic understanding of these scientific findings.
Imperfection is beautiful.
