In a conversation I had with Stuart Kauffman on Star Island, NH in 2006 I told him that I had found his latest book--At Home in the Universe at that time--a difficult read. He responded that that made him sad because he had tried his best to keep it simple. I assured him that that was my problem and not his.

He obviously has done a better job in his latest book, Reinventing the Sacred, in writing for the non-expert audience. While portions of the book were difficult for me, eg, the chapter on the "Quantum Brain", the book overall is much more comprehensible to me personally. I'm sure that others with a deeper background in complexity theory and science will find the book very understandable.

The author shows courage in presenting a new (to me) scientific paradigm--emergence--and in offering what are, in his own words, highly controversial suggestions and potential methods of investigating these suggestions. Graduate students and post-docs should find a wealth of ideas for future research in this book.

As a religious naturalist I appreciate the author's writing of "naturalizing the sacred" and suggesting that he is only the latest of many thinkers who would like to hold on to the god symbol because of its power accumulated over the centuries and across cultures. Kauffman's erudition and graciousness come through in his writing, especially in the latter parts of the book as he pleads for a better understanding of our "evolving ethics" that hopefully will lead to a desperately needed "global ethic". Because we cannot foresee the future--a key feature of emergence--we must nevertheless "live our lives forward, with courage and faith." I think I will.

As usual, Kauffman pushes the conceptual envelope. He argues that the future is inherently unpredictable and goes on to derive a philosophy of meaning from that unpredictability. He even joins Roger Penrose in hypothesizing a role for quantum superposition in fostering free will and the unpredictability of the future. Don't read Kauffman for a simple tour of the scientifically known. He pushes into unknown territory with plausible but unproven ideas. A good read if you have a taste for this kind of thing. ( )
