Author of over three hundred research papers on the mathematical, physical, and philosophical foundations of quantum mechanics, and a Springer book 'Mind, matter, and quantum mechanics'. Worked personally with W. Heisenberg, W. Pauli, and J.A. Wheeler on these issues. Invited author of entries about quantum theories consciousness in several currently about to appear encyclopedias. Invited plenary speaker at numerous international conferences. For book cover: Henry Stapp has spent his entire career working in frontier areas of theoretical physics. After completing his thesis work under Nobel Laureates Emilio Segré and Owen Chamberlain, he joined Wolfgang Pauli to tackle foundational issues. After Pauli's early death, he turned to von Neumann's ideas about the mathematical foundations of quantum theory. The essay 'Mind, Matter and Quantum Mechanics', that developed out of this work eventually evolved into Stapp's classic book bearing the same title. His deep interest in the quantum measurement problem led him to pursue extensive work pertaining to the influence of our conscious thoughts on physical processes occurring in our brains. The understandings achieved in this work have been described in many technical articles and now, in more accessible prose, in the present book.

This book offers an accessible treatment of mind versus matter. It discusses the ethical consequences of the mind versus matter debate, and describes how quantum mechanics can radically change our understanding of the connection between mind and brain.

The classical mechanistic idea of nature that prevailed in science during the eighteenth and nineteenth centuries was an essentially mindless conception: the physically described aspects of nature were asserted to be completely determined by prior physically described aspects alone, with our conscious experiences entering only passively. During the twentieth century the classical concepts were found to be inadequate. In the new theory, quantum mechanics, our conscious experiences enter into the dynamics in specified ways not fixed by the physically described aspects alone. Consequences of this radical change in our understanding of the connection between mind and brain are described. This second edition contains two new chapters investigating the role of quantum phenomena in the problem of free will and in the placebo effect.
