Gottfried Wilhelm von Liebniz was a philosopher and mathematician in search of a model. In the late 1600s Leibniz decided there was a need for a new, purer arithmetic than our common decimal (十进制) system. He got his inspiration from the 5000-year-old book that is at the heart of Chinese philosophy: the I-Ching, or Book of Changes.
This ancient text was such an influence on Liebniz that he titled his article on the new arithmetic "Explanation of a new arithmetic and the ancient Chinese figure of Fu X". Fu Xi was the legendary first author of the I-Ching. The arithmetic that Liebniz described was binary (二进制) code, which is used in almost every modern computer, from iPhones to China's own Tihane-2 supercomputer.
To figure out what Liebniz learned in the I-Ching, we need to understand something that most of us have taken for granted. When we listen to an MP3, look at a digital photo or watch the latest TV drama, we are experiencing a digital representation of reality. That representation is basically just a string of binary signals that are commonly known as 1s and 0s. What Liebniz's gained from the book was that even the most complex reality could be represented in the binary form as 1s and 0s.
In the philosophy of the I-Ching, reality is not entirely real. It is something more like a dream. This dream of reality arises from the binaries of Yin and Yang, as they play out countless combinations, practically everything in the universe. It's not surprising then, from the l-Ching's perspective, that anything in the dream of reality can be represented in a string of 1s and 0s, processed by a computer.
The I-Ching was far more ambitious than the current practical applications of binary code. It is claimed that the I-Ching represents nothing less than the basic situation of human life itself. As a system for predicting the future, the I-Ching might disappoint, but as a way of questioning your own unconscious mind, it can be remarkably useful.
The I-Ching's teachings also contain warnings about our digital revolution. Binary code, powered by modern computers, has an amazing capacity to represent reality. However, the ancient authors of the I-Ching might have understood its potential-and its dangers-even better than we now do.
So when scientific thinkers ask whether computers can create "virtual realities" or "artificial intelligence", they are missing the point. Of course, we can create ever deeper and more complex layers of the dream of reality. The real question is, can we wake up from the dream we're in already?
