New Scientist rejects Scientism

TOP DOWN REDUCTIONISM...

...ENDS UP BEING CIRCULAR!

I came across this short New Scientist video illustrating some ideas that have been bouncing around the Buddhoblogosphere for a few years in one form or another.

The video points out the logical contradictions of reductionism ("the mind is nothing but the brain, which is nothing but a biological machine, which nothing but etc..."). This is something of a change of direction for this magazine, which has previously tended to support physicalism and scientism.

What the video is saying is that all attempts at reductionism end in circularity, and you need consciousness to explain consciousness (a philosophical position known as Ontologicial Mysterianism). 

I have a few quibbles about oversimplification, but maybe this is necessary to get the message across. The video concentrates exclusively on structure, and ignores process and operations.  This becomes apparent in the oversimplification of the Von Neumann derivation of numbers, where numbers spontanously appear out of nothing.  In fact it is the operation of the mind on the empty set which produces these numbers.

The video is saying that...

- Mathematics is reducible to mind.

- Mind is reducible to biological macromolecules.
 
- Biological macromolecules are reducible to organic chemicals.

- Organic chemicals are reducible to atoms.

- Atoms are reducible to mathematics.

- Mathematics is reducible to mind.

... which is where we came in!



I would reformulate this as ...

- The structures and operations of mathematics are reducible to the concepts and operations of the mind.

- The structures and  operations of the mind are reducible to the structures and operations of biological macromolecules.
 
- The structures and operations of biological macromolecules are reducible to the structures and operations of organic chemicals.

- The structures and operations of organic chemicals are reducible to the structures and operations of atoms.

- The structures and operations of atoms are reducible to the structures and operations of mathematics.

- The structures and operations of mathematics are reducible to the concepts and operations of the mind...  (deja vu)

This is, of course, another illustration of emptiness, in that no rock-bottom foundation for any phenomenon is findable. 

 

Here it is -  enjoy WHAT IS REALITY

 ...and if you are interested in further disproofs of materialistic reductionism, then consider that...

The behavior of all machines, computers and physical systems is reducible without remainder to the operations of a Turing machine.

The behavior of the mind shows at least two functions - 'aboutness'  and qualitative experience - that cannot in principle be reduced to the operation of a Turing machine.

Therefore, there are some aspects of the mind that are non-mechanistic and non-physical.

Artificial Intelligence - 1950's Style

Mind and Machine

Scientism (not science itself as some people seem to believe)  is the major enemy of spirituality.  Scientism is a bleak and barren materialism that tries to reduce all aspects of the human mind to the workings of a biological machine, with no room for any spiritual or aesthetic dimension to life.

While Buddhism is quite happy with science in general, and especially with evolution, it doesn't agree with the materialistic dogma of scientism, and disputes claims that the mind can be explained or understood in physical terms. Most Buddhists  believe that the mind's ultimate nature is non-physical: 'when the body dies the 'mechanism' of the body, holding the spirit is gone and the spirit finds a new body sooner or later, perhaps immediately.'  - Alan Turing (Code Breaker, Mathematician and Buddhist Philosopher)

Scientism

Scientism is a misuse of scientific methodology beyond the limits of its applicability, including attempts to reduce all knowledge to only that which can be understood by mechanistic models. Scientism attempts to reduce all qualitative experience, and indeed all mental phenomena, to physical causes, effects and mechanisms. 

To understand why scientism is overreaching and erroneous, we need first to understand the limits of science.

The Limits of Science

The physics-based sciences construct their models, predictions and explanations by abstracting and reducing the numerous natural instances of processes operating on structures, into a few generic procedures operating on data.

Hence physical explanations will be impossible to construct, will fail, or will be inapplicable as 'category errors' for any phenomena where...

(i) Processes cannot be reduced to procedures
(ii) Structures cannot be reduced to data

I suspect that one of the intractable features of The Hard Problem is that some of the processes of consciousness are not even in principle reducible to procedures (they are 'non-algorithmic'). Similarly, qualia cannot be reduced to data. Consequently, attempts at physical explanations of the mind may be  such category errors.

The domain of science concerns those aspects of the world that can be modelled effectively and efficiently in terms of algorithms and data-structures.

'Effectively' means that the models have predictive power (and hence are falsifiable).

'Efficiently' means that the models are simpler and more general than the phenomena that they model (they embody 'algorithmic compression')

All non-algorithmic phenomena, by their very nature, are outside the scope of the physical sciences.

A materialist explanation for the mind?

Consequently, the the 'materialists',  'physicalists',  'reductionists'  and other practitioners of scientism are committed to trying to represent the three-dimensional world of causality, composition and mind, in terms of the two dimensions of algorithms and datastructures. 

This representation ultimately requires them to insert various square pegs (qualia, semantics, intentionality, freewill etc) into the round hole of computationalism.  But computation can only deal with quantitative and Boolean-logical values. It cannot manipulate any qualitative phenomena.

The lack of progress with The Hard Problem of Consciousness is one of the best illustrations of the failure of the materialist's project.

Scientism has failed to bridge the gap between brain and mind

The Abject Failure of Scientism

The Hard Problem, the realisation that the mind is not explainable mechanistically, and is thus beyond the scope of science, was first formulated by the eminent Victorian physicist John Tyndall over 140 years ago:

"... the passage from the physics of the brain to the corresponding facts of consciousness is unthinkable. Granted that a definite thought, and a definite molecular action in the brain occur simultaneously; we do not possess the intellectual organ, nor apparently any rudiment of the organ, which would enable us to pass, by a process of reasoning, from the one to the other. They appear together, but we do not know why.

Were our minds and senses so expanded, strengthened, and illuminated, as to enable us to see and feel the very molecules of the brain; were we capable of following all their motions, all their groupings, all their electric discharges, if such there be; and were we intimately acquainted with the corresponding states of thought and feeling, we should be as far as ever from the solution of the problem, "How are these physical processes connected with the facts of consciousness?" The chasm between the two classes of phenomena would still remain intellectually impassable.

Let the consciousness of love, for example, be associated with a right-handed spiral motion of the molecules of the brain, and the consciousness of hate with a left-handed spiral motion. We should then know, when we love, that the motion is in one direction, and, when we hate, that the motion is in the other; but the "Why?" would remain as unanswerable as before."

Everything we have learned about the structure and physiology of the brain in the century and a half since Tyndall's statement has taught us a lot about the structure and physiology of the brain.  It has not progressed one inch towards closure of the explanatory gap of the Hard Problem.
