Quantum for Buddhism
by Christian Thomas Kohl, Taipei Times, March 30, 2008
Freiburg, Germany -- What is reality? The mindsets of the modern world provide four answers to that question and oscillate between these answers:
1. The traditional Jewish, Islamic and Christian religions speak about a creator that holds the world together. He represents the fundamental reality. If He were separated only for one moment from the world, the world would disappear immediately. The world can only exist because He is maintaining and guarding it. This mindset is so fundamental that even many modern scientists cannot deviate from it. The laws of nature and elementary particles now supersede the role of the creator;
2. Rene Descartes takes into consideration a second mindset, where the subject or the subjective model of thought is fundamental. Everything else is derived from it;
3. According to a third holistic mindset, the fundamental reality should consist of both subject and object. Everything should be one. Everything should be connected with everything; and
As Buddhism refuses these four concepts of reality, it was therefore confronted with the reproach of nihilism. If you don't believe in a creator, or in the laws of nature, or in a permanent object, or in an absolute subject, or in both, or in none, what do you believe in, then? What remains that you can consider a fundamental reality? The answer is simple -- it is so simple that we barely consider it being a philosophical statement.
Things depend on other things. For instance: A thing is dependent on its cause. There is no effect without a cause and no cause without an effect. There is no fire without a fuel, no action without an actor and vice versa. Things are dependent on other things; they are not identical with each other, nor do they break up into objective and subjective parts.
This Buddhist concept of reality is often met with disapproval and considered incomprehensible. But there are modern modes of thought with points of contact. For instance: There is a discussion in quantum physics about fundamental reality. What is fundamental in quantum physics: particles, waves, field of force, law of nature, mindsets or information? The results of quantum physics are expressed by the key words of complementarity, interaction and entanglement.
According to these concepts, there are no independent but complementary quantum objects; they are at the same time waves and particles. Quantum objects interact with others and they are even entangled when they are separated by a far distance. Without being observed philosophically, quantum physics has created a physical concept of reality. According to that concept, the fundamental reality is an interaction of systems that interact with other systems and with their own components.
This physical concept of reality does not agree upon the four approaches mentioned above. If the fundamental reality consists of dependent systems, then its basics can neither be independent and objective laws of nature nor independent subjective models of thought. The fundamental reality cannot be a mystic entity nor it can it consist only of information.
The concepts of reality in Buddhism surprisingly parallel quantum physics.
