Get Real:

A Philosophical Adventure in Virtual Reality

a book by
Philip Zhai


"Get Real has the potential to become a landmark in both philosophy and virtual reality. The clearly written text progresses systematically through one hard issue after another. Whether or not one agrees with all of the conclusions, this is a book to be studied and then restudied." -- Dr. Lawrence Auld

Steer your passion out of the little nest
Inhale the whole space into your chest
Stage your final ontological protest
Let the eternal light unfold all the rest

"New Genesis," Z. Zhai, 1997

"We can never re-create the human mind through AI, but we can re-create the whole empirical world through VR," the author makes such a radical yet convincingly justified claim.

Is Virtual Reality merely a video game that totally consumes and distracts the player immersed in its simulations? Or is VR an immaterial world rich with meaning that beckons humanity to migrate into a better future world held inside computers? Philip Zhai tackles this contemporary question with keen logical analysis and concludes by advocating a standpoint that transcends these two opposing views of Virtual Reality.

According to Zhai, the combination of the three technologies -- digital simulation, sensory immersion, and functional teleoperation-- in a well-coordinated manner amounts to a Re- Creation of the whole empirically perceived universe. This is not a mere metaphor of Trinity. Virtual Reality could literally replace the actual reality if we choose to live in this newly-created world. Zhai in this book provides an ontological proof based on astounding yet carefully crafted thought experiments and cogent philosophical reasoning. He leads us to realize that: 1) whatever reasons we have for justifying the materiality of the actual world will have the equal validity for justifying the materiality of the virtual world once we are immersed in it; 2) whatever reasons we have for calling perceived objects in the virtual world illusory are equally applicable for calling those in the actual world illusory; 3) whatever functions we need to perform in the actual world for our survival and prosperity, including production and procreation, can also be performed in the virtual world. The danger lies, however, in the possibility of a total reality blackout when the Reality Engine breaks down, which is comparable to a natural disaster on the cosmic level in the actual world.

Zhai also provides a rigorous analysis of why strong AI as proposed by Daniel Dennett and other believers is impossible and why John Searle's criticism is off the mark and also fallacious. He shows how the parallelism between the virtual and the actual world must hinge upon the unity of the human mind as the center of perception, which is the pre-condition for the spatial locality of the empirical world.

Later chapters deal with the normative issue of the desirability of Virtual Reality. The discussion is based on the author's highly original concept of Humanitude developed in his previously published book. He draws on various classical philosophers and also argues with contemporary thinkers through masterful logical analyses and lively phenomenological descriptions. According to him, the only important difference between the actual and the virtual world is that we are co-creators of the latter: Gods 'R Us.

As Michael Heim -- internationally known as "the philosopher of cyberspace" -- says, "Zhai's book is a must-read for anyone interested in the implications of simulation and immersion technology." The thought experiments presented here are as mind- boggling and entertaining as any plots in a science fiction story, yet they are able to put you into alternating states of excitement and enlightenment. If you are a seasoned philosopher, chapters on VR's implications for philosophy of mind and other metaphysical issues will very likely challenge you to re-examine the starting point of philosophical reasoning; if you are a beginner, this book will lead you from the ground up to the frontier of the philosophical enterprise. If you work in a technical field of VR or information industry at large, this book will help you form a clear vision about the future possibilities of electronic revolution. In general, anybody with a decent educational background will benefit a great deal from reading this eye-opening and groundbreaking book.

Philip Zhai holds a Bachelor's degree in engineering and a Ph.D. in philosophy. He is the author of the book, The Radical Choice and Moral Theory, and numerous articles. He also plays musical instruments and composes music. He has taught philosophy at Univ. of Kentucky, Muhlenberg College, Millsaps College, Moravian College. He has also been invited to deliver lectures around the world on various occasions. He is now spending most of his time on designing and writing software programs, while continuing to write philosophy books.
