Buddhism and quantum physics
Op-Ed: Christian Thomas Kohl
Freiburg, Germany, March 11 — What is reality? The mindsets of the modern world provide four answers to the 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. René Descartes takes into consideration a second mindset where the subject or the subjective model of thought is fundamental. Everything else is nothing but 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.
4. A fourth and very modern mindset neglects reality. We could call it instrumentalism. According to this way of thinking, our concepts do not reflect a single reality in any one way. Our concepts have nothing to do with reality but only with information.
Buddhism refutes these four concepts of reality. Therefore, it confronts the reproach of nihilism. If you do not believe in a creator or in the laws of nature, or in a permanent object, or in an absolute subject, or none of it, then what do you believe?
What remains if one considers 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 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 is 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? Is it particles, waves, field of force, laws of nature, mindsets or information?
Quantum physics came to a result that is expressed by key words like complementarities, 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 entangled even when separated by long distances.
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 earlier.
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 can it consist of information only.
The concepts of reality in Buddhism surprisingly parallel quantum physics.
