doctrine of Physical Reductionism - that life has no spiritual dimension - is sometimes
openly stated, but often jjust accepted as the default materialist view.
Reductionism states that:
The mind is nothing but the brain.
The brain is nothing but a biological system.
Biological systems are nothing but chemical interactions.
Chemical interactions are nothing but physical interactions.
Therefore the mind is nothing but a set of physical interactions.
This hierarchy exists as bottom-up `objective reality'. If you removed the top level then
the rest of the structure would be unaffected.
From a Buddhist standpoint, the reductionist argument is flawed at the top ('The Hard
Problem'). It is flawed at the bottom (quantum-mind interactions and the
effectiveness of mathematics), it is flawed in the middle (the problem of emergence), and it is flawed
ontologically (There is no inherently-existent
objective reality. Mother nature doesn't make statements, she only answers questions, and
the questioner is part of the system).
Buddhism and 'The Hard Problem'
The 'Hard Problem' is that there is no explanation of how neurological activity
could turn into subjective experience. Not only is there no explanation, but no one has
any idea of what such an explanation would look like.
Even worse (for the reductionists) there's a
growing suspicion that The Hard Problem is in fact what's known as a `category error' or
'category mistake'. In other words, no explanation of subjective experience in terms of
physico-chemical brain activity is possible. Another dimension of reality is required.
There is a huge, vast, gaping explanatory gap between brain processes ('neural
correlates') and mental experience.
Mental experience cannot be explained in terms of causes and conditions nor structures of
the brain. There are correlations, but no explanations.
This shouldn't be surprising if we remember teachings on sunyata, that the three irreducibhle
aspects of all phenomena are:
(1) Causes and conditions
(2) Structures - relations of wholes to parts and spects, and vice versa.
(3) Mental imputation.
Mental imputation is associated with, but cannot be reduced to the two other aspects. The
mind is an irreducible feature of reality.
If you were to put it in Buddhist terminology I suppose you would say that the brain is
not a valid basis of imputation for the mind (and any case what would be the entity that
was doing the imputing?).
The short circuit from mind to
The flaw at the bottom level is that there seems to be a direct connection to the
top level which doesn't go through the hierarchy. The links between the behaviour of fundamental particles and the
activities of the mind are suspiciously close.
There are fascinating parallels between what physicists have learned about sub-atomic
physics and the Buddhistm ideas of emptiness and dependent origination. In addition, as
Einstein famously remarked "The most incomprehensible
thing about the universe is that it is comprehensible"
The problem of emergence
The flaw in the middle is the lack of equivalence in both directions (aka
the problem of emergence). You can logically go down the hierarchy, but not up it. From
observing the behaviour of sub-atomic particles you could not even deduce the existence of
turnips, let alone brains, though close examination of both turnips and brains would lead
to the discovery of their consituent particles.
`Nothing but' is untrue, because there is some mysterious `extra
ingredient' being added as you go up the hierarchy.
So we will have to replace the phrase `is nothing but' by `is understandable
in terms of', and do a few more corrections as well.
The mind is NOT understandable in terms of the brain. The brain is understandable in terms
of biological systems.
Biological systems are understandable in terms of chemical interactions.
Chemical interactions are understandable in terms of physical interactions.
Physical interactions are understandable in terms of mathematics.
Mathematics is a product of the mind.
Now, forget the bottom and top and just look at the middle level of the hierarchy. Can you
see the mysterious missing ingredient? Where does the understanding come from?
Let's turn the middle layers upside down and rephrase using Buddhist terminology...
Physical interactions are the basis of imputation of chemical reactions.
Chemical interactions are the basis of imputation of biological systems
So even at the more mundane intermediate levels of this supposedly objective reductionist
hierarchy, mental imputation is present all the time.
Mind is an irreducible aspect of reality inseparably intertwined with all levels of the
Buddhists have nothing to fear from Science
Maybe Buddhists need to put more effort into combining arguments from
science and Buddhism to demolish the deluded view of Reductionism ( aka Materialism aka
Physicalism aka Naturalism).
Buddhism is grounded in philosophy, and has nothing to fear from science, not even from Darwin's Universal Acid which corrodes
The bleak, deluded view of Materialist Reductionism is not only a major obstacle to the
spiritual progress of those who (often reluctantly ) suffer from it, but it also generates
fear, aggression and denial in those who oppose it but don't know how to argue against it.
This denial and aggression against Materialism manifests as anti-science, irrationalism,
bigotry, Creationism, Biblical literalism and is quite possibly a contributory factor to Jihadism.
But there's no reason for Buddhists to adopt the same head-in-the-sand turn-the-clock-back
approach. Buddha didn't tell us to criticise and examine his teachings for no reason. He
knew that his Dharma rested on the unassailable metaphysical foundation of sunyata.
After aggressive fundamentalism, reductionist materialism is the greatest obstacle to
spiritual progress in the modern world. Any path that can blast its way through this
obstacle will provide an escape route for millions of migrators.
