*The fall of the economists’ empire *

*By **ROBERT SKIDELSKY* <https://www.asiatimes.com/author/robert-skidelsky/>

The historian Norman Stone, who died in June, always insisted that history
students learn foreign languages. Language gives access to a people’s
culture, and culture to its history. Its history tells us how it sees
itself and others. Knowledge of languages should thus be an essential
component of a historian’s technical equipment. It is the key to
understanding the past and future of international relations.

But this belief in the fundamental importance of knowing particular
languages has faded, even among historians. All social sciences, to a
greater or lesser degree, start with a yearning for a universal language,
into which they can fit such particulars as suit their view of things.
Their model of knowledge thus aspires to the precision and generality of
the natural sciences. Once we understand human behavior in terms of some
universal and – crucially – ahistorical principle, we can aspire to control
(and of course improve) it.

No social science has succumbed to this temptation more than economics. Its
favored universal language is mathematics. Its models of human behavior are
built not on close observation, but on hypotheses that, if not quite
plucked from the air, are unconsciously plucked from economists’
intellectual and political environments. These then form the premises of
logical reasoning of the type, “All sheep are white, therefore the next
sheep I meet will be white.” In economics: “All humans are rational utility
maximizers. Therefore, in any situation, they will act in such a way as to
maximize their utility.”

This method gives economics a unique predictive power, especially as the
utilities can all be expressed and manipulated quantitatively. It makes
economics, in the late American Nobel laureate Paul Samuelson
<https://www.nobelprize.org/prizes/economic-sciences/1970/samuelson/biographical/>’s
words, the “queen of the social sciences.”

In principle, economists don’t deny the need to test their conclusions. At
this point, history, one might have thought, would be particularly useful.
Is it really the case that all sheep are white, in every place and clime?
But most economists disdain the “evidence” of history, regarding it as
little better than anecdotage. They approach history by one route:
econometrics. At best, the past is a field for statistical inquiry.

Economist Robert Solow offers a devastating critique
<https://www.jstor.org/stable/1805620?seq=1#page_scan_tab_contents> of the
identification of economic history with econometrics, or “history blind” as
he calls it:

“The best and brightest in the profession proceed as if economics is the
physics of society. There is a single universally valid model. It only
needs to be applied. You could drop a modern economist from a time machine
… at any time, in any place, along with his or her personal computer; he or
she could set up in business without even bothering to ask what time and
which place.”

In short, much of the historical modeling economists do assumes that people
in the past had in essence the same values and motives as we do today.
Another Nobel laureate economist, Robert Lucas, carries this approach
<http://people.bu.edu/chamley/HSFref/Lucas-citiesJME88.pdf> to its logical
conclusion: “the construction of a mechanical, artificial world, populated
by … interacting robots … that is capable of exhibiting behavior the gross
features of which resemble those of the actual world.”

The goal of economics is to replace the particular languages that obstruct
the discovery of general laws with the universal language of mathematics.
Elon Musk takes Lucas’ interacting robots one step further, with his
ambition to link the human brain directly to the world (which includes
other human brains). Our thoughts will be directly socialized without the
intermediation of any language. When you think “door, open!” it does.
Whereas economists dream of putting God in their models, the robotic
utopians dream of reversing the fall of man by creating godlike humans.

To be clear, this is the apotheosis of a Western conceit. The West still
views itself as the bearer of universal civilization, with the non-West no
more than a lagging cultural indicator. In the West itself, the authority
of economics has diminished, but this hasn’t dented the West’s propensity
to export its civilization. “Good economics” has been partly replaced by a
commitment to universal human rights as the means to save the world from
itself, but the purpose is the same: to lecture everyone else on their
shortcomings.

Here, we encounter a paradox. The triumph of universalism has come just
when Western power is collapsing. And it was that power that made Western
thought seem universal in the first place. Conquest, not missionaries,
spread Christianity around the world.

The same is true of Western social science and Western values in general.
The non-West bought into the Western model of progress, especially economic
progress, because it wanted to free itself from Western tutelage. This
still gives economics (a Western invention) its edge. It’s a kind of white
man’s magic. But without the power and authority behind the magic, its
appeal is bound to fade. The non-West will still want to emulate the West’s
success, but will pursue it by its own means. The University of Chicago and
Massachusetts Institute of Technology will give way to universities in
China or India, and the non-West will choose which Western values to
embrace.

Yet the world needs something universal to give us a sense of shared
humanity. The big challenge – to use that overworked word – is to develop
what the philosopher Thomas Nagel called a “view from nowhere” that
transcends both cultural fetishism and scientism, and does not force us to
choose between them. This is a task for philosophy, not economics.
