This is my contribution to Tibet and the dialogue between East and West: 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
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.
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.
