Mind, Matter, and the Implicate Order by Paavo T. I. Pylkkänen is a highly recommended book for anyone who wants to understand David Bohm’s work better.  It’s not fair to Dr. Pylkkänen to suggest this book is only about Bohm’s work.  While Bohm’s work is the focus of this book, this book is broader in focus than only Bohm’s work and Dr. Pylkkänen attempts to extend and go beyond Bohm’s work.  Dr. Pylkkänen is a philosopher who was a colleague and friend of David Bohm.  Dr. Pylkkänen comments on the necessity of understanding concepts from the physical sciences in order to have the proper context to speak about mind and consciousness.  Many philosophers who comment on mind, consciousness, and their relationship to matter are using very antiquated understandings of matter that are causing confusion.  When Dr. Pylkkänen refers to the physical sciences he is refering to modern developments in physics, especially as articulated by David Bohm, and these notions of the physical are radically different than colloquial understandings of the same.  The issue of relating the mental to the physical is an underlying theme of this book and Dr. Pylkkänen presents Bohm’s work as a new and fertile grounds to sketch that relation in a new way.  In exploring the issue or relating the mental and the physical Dr. Pylkkänen goes to lengths to explain many of Bohm’s central ideas.
