The Metaphysics of Virtual Reality

by Michael Heim

Book Overview

Computers have dramatically altered life in the late twentieth century. Today we can draw on worldwide computer links, speeding up communications by radio, newspapers, and television. Ideas fly back and forth and circle the globe at the speed of electricity. And just around the corner lurks full-blown virtual reality, in which we will be able to immerse ourselves in a computer simulation not only of the actual physical world, but of any imagined world...

How to really play God

No one disputes that the growing sophistication of computing technology has altered the human condition. With the current world population in excess of five billion and the U.S. economy in excess of six trillion dollars annually, computers are essential to the management of life. However, few people ever think about how much this has altered the perception of existence. Philosopher Michael Heim is one such person.The imminent, but distant development of Artificial Intelligence has forced a thorough rethinking of what human intelligence really is. The Turing test, where a computer interacts with a human via teletype and passes the test if the human thinks that the object on the other end is also human, has been proven inadequate. Other abilities, such as being able to perform extensive arithmetic computations, is also not an indicator of intelligence. As amazing as it may seem to the child struggling to learn their 'rithmetic, the algorithms are just not that complicated. The only conclusive result to date is that intelligent behavior is ill-defined. The best that can be agreed upon is a statement similar to that uttered by a justice of the United State Supreme Court. When asked to define pornography, his response was, "I can't define it, but I know it when I see it." Robotics, computer viruses and the nebulous discipline of Artificial Life are forcing a re-examination of what life is. Capable of reproducing, but only with the assistance of other objects, computer viruses are remarkably similar to their biological counterparts. Arguing that they are fundamentally different because they are nothing more than a series of instructions misses the point. A biological virus is a set of instructions coded in either RNA or DNA, both of which allow for four options, and is surrounded by a protective protein coat. The computer virus is stored in two option binary on a protective magnetic or optical medium. Each is extremely vulnerable when the instructions are isolated. For the biological virus, this is when it has infected a host and the instructions are free of the protective coat. In the case of the computer virus, this is when the instructions are in working memory . Artificial life, generally cellular automata, do many of the things commonly associated with life, including the ability to evolve into other forms. Like all dynamic systems with a random component, this evolution can be in either direction, to more or less "advanced." Again, the argument that a cellular automaton is nothing more than a series of precise instructions being sequentially executed has been rendered invalid. Whatever force you assign to human and animal existence, the core of life is a series of instructions coded in genetic material and requiring outside power sources to function.While the development of AI and AL are forcing significant alterations in human perceptions of existence, those alterations will be dwarfed by the changes wrought by the advent of Virtual Reality.

The Metaphysics of Virtual Reality

If you search through the internet on the definition of VR, you'll hit on just about anything having to do with computers. Why? Heim attempts to answer this question with a wonderful explanation of what the term has meant, means now, and may mean in both the near and far future. He reviews the impact products have had on our daily lives, which we take for granted today, and studies what past philosophers feared--have these fears become a reality? The book defines our relationship to computers now, and what our expectations are. It's a fun little book to read. It'll make you stop and think about our real world when your done.
