The Idea Delusion

Recently, a postgraduate student asked me, as part of his thesis (http://vasilis-thesis.blogspot.com/) , to comment on the following claims by Keynes and Galbraith.
Keynes claimed that: "The ideas of economists and political philosophers (etc), both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed the world is ruled by little else.” While Galbraith argued that: "Ideas would be powerful only in a static world because they are inherently conservative."
The student’s question was: These statements were said almost 45, and more, years ago. According to your opinion, which of the fore mentioned statements seems valid in the modern world?
My answer was: “I would definitely side with Galbraith. Of course ideas appear to be powerful and they seem to exercise enormous influence in the way we perceive and interpret the phenomena of the world. I believe that Pol Pot is a case in fact, as well as the hapless millions that were killed because of political ideas that he carried inside his head. But were those millions killed because of political ideology, or because this ideology "happened" to take root in Pol Pot's head, who "happened", through an amazing series of coincidences to live long enough and become powerful enough in order to enact those ideas against the poor people of Cambodia? Alas, our world is not shaped by decisions but by happenstance, by the dynamic confluence of sometimes interconnected and sometimes disparate factors, that lead one way or the other, by virtue of systemic forces beyond our control - or comprehension. Only by hindsight do economists and political philosophers apply ideas to the facts and develop their "theories". The feeling of "power" ascribed in their ideas is therefore an illusion, and it has been so not only today but always and forever.”

I would like to expand somewhat on my answer. Firstly, let me point out that I am referring to economic and political philosophy, restricting therefore my tackle of the term “Idea” - at least for now - to these fields.

I believe the ultimate acid test that shows the delusion that I am claiming is very simple. Economic and political theorists develop ideas which explain (or try to explain) the past. Even those theorists who claim that they speak about “today” or the “present” are in fact speaking only about the past; the recent past but the past nevertheless. The “present” is physically and intellectually unattainable as any Zen story will easily convince you. All economic and political theory, every “big idea” – Marxism, anarchism, liberalism, whatever - fails in various degrees when it comes to predicting the future. Why is this so? Why can’t anyone tell us how the world or the economy will be in five, or ten years time or, in fact, tomorrow morning?

Two reasons: Firstly, economic and political theories do not have – not yet anyway – a solid scientific base on the natural sciences. Secondly, economic and political theorists do not really believe that they need such a base in order to develop and debate their ideas. They inherently accept that the economy and the society are governed by non-natural forces and laws and that they are “human-made” – whatever that may mean. Therefore, they strongly contend that their theories and ideas are, or potentially could be, the driving forces of economic and social phenomena. That, for example, “believing” in market economics, “accepting” the theory and developing instruments that support it (e.g. IMF, World Bank, etc.) will surely transform the world into a free market economy. That invading Iraq and installing a western-type democracy will transform Iraq into a western-type democracy. These notions are delusions, of course. It should be very obvious to any rationally thinking person that human beings and societies are not controlled, “closed” environments of deterministic interactions. We are a social class of animals partaking in the evolution of the cosmos whether we want it, think it, or not.
I suggest that the roots of this “Idea Delusion” are Platonic and rest with Plato’s Republic. It is, however, about time, that such a delusion is revised and economists and sociologists begin to approach the workings of society in the same way as natural philosophers and natural scientists do. We need a new paradigm of social and economic theory based on biology and systems theory with predictive powers. Ideologies belong to the past.

Simulation and non-local realism

Realism is the viewpoint according to which an external reality exists independent of observation. According to Bell’s theorem any theory that is based on the joint assumption of realism and locality (meaning that local events cannot be affected by actions in space-like separated regions – something that Einstein would not swallow) clash with many quantum predictions. In such cases, “spooky action at a distance” is necessarily assumed in order to explain phenomena such as quantum entanglement. This is called non-local realism. A recent paper by Simon Groblacher et al (An experimental test of non-local realism, Nature, Vol. 446, 19th April 2007, pp. 871-5) showed that giving up the concept of non-locality is not sufficient to be consistent with quantum experiments, unless certain intuitive features of realism are also abandoned. Let us see how these results may correspond to assumptions made into our simulation-based New Narrative.
I would like to take an example from cosmology, indeed the very simulation of the standard cosmological model. The logic of the simulation goes like this. Assumption 1: The universe maps unto an external reality which, somehow (i.e. via known, or unknown-as-yet, natural laws) maps also unto our coupled media of detection instruments plus consciousness. This may be called “the perceived universe”. It usually depicts an image of the cosmos, galaxies and gas clusters spreading in all directions and in all magnificence. A mathematical model is then developed based on the prevailing cosmological theory that aims to explain the “perceived universe”. This model runs on a computer, which is the external reality substrate of the simulation. In other words, there is, or so we assume, a “reality” of hardware that runs our simulation (assumption 2). The result of the simulation is also an image of the cosmos. Comparing the two images we refine the model further until the two images appear identical. When we achieve an identical pair of images then we conclude that our mathematical model has been a successful one, i.e. a valid description of external reality.
It is obvious that our conclusion may be potentially flawed, on the basis of our two main assumptions. Furthermore, our assumptions call upon the quantum nature of the cosmos which, as the aforementioned paper has demonstrated, seems to reject non-local realism. Thus, we are left with a revision of assumptions about realism.
Which happen to be inherent in the New Narrative, the most poignant revision of reality being the decoherence of Selfhood.
By deconstructing the Self, by rejecting the narcissism of psychoanalysis, by re-introducing a mystical layer of dualism in the nature of consciousness, we arrive at a counterfactual definiteness and in a world not completely deterministic. The result may be a chorus of out-of-tune artwork but it is also a result closer to what our best validated experiments show. If “external reality” is a wonderland of curious objects and events then our revised “inner reality” of the New Narrative is an equally exotic place. But should we take such a phantasmagoric correspondence as a sign of progress? Should we convince ourselves that we have, at last, by entering our self-simulated world, arrived serendipitously at the Holy Grail of “reality”? Ironically perhaps, the very dynamics of decoherence prevent us from answering such questions. When determinism is thrown out of the window, then all one can do is lean onto the ledge and peer outside, in wander and astonishment, to the changing view of a perplexing world beyond our wildest imagination. And that is exactly what the New Narrative tries, and forever fails, to describe.
