Economics IS a Science!

In the comment section to Joe Romm’s third post on the evil of economists a very interesting comment surfaced. (My previous post links to Romm’s earlier attacks and some responses.) It is signed by ‘Asteroid Miner’ (comment no. 7):

Economists think that they are scientists. They are not. Science deals with NATURE, not man-made things like markets and money. Science requires and is based on public and replicable experiments. Computer simulations don’t count. Social sciences are suspect, but not as bad as economics. SCIENTIFIC EXPERIMENTS ARE NOT POSSIBLE IN ECONOMICS.

Economics presupposes the existence of a stable civilization and the invention of money. A stable civilization with money requires creatures that are at least marginally rational and intelligent and slightly knowledgeable. A stable civilization also requires an adequate food supply. The collapse of agriculture inevitably leads to the collapse of civilization and the collapse of money and economics. Economics is unable to go outside of its founding presuppositions. Global warming climatology MUST concern itself with the collapse of civilization and the possible extinction of the supposedly rational intelligent knowledgeable creatures. Climate change is therefore impossible for economists to imagine AS LONG AS THEY REMAIN ECONOMISTS.

Thus the problem of economists who speak on the subject of global warming. Being economists, they assume the impossible, which is that agriculture will not collapse, civilization will not collapse and Homo Sapiens will not go extinct. Being economists, they are unable to imagine anything outside of the basic presuppositions of economics. They have made those assumptions implicitly since long before their careers began. They cannot do otherwise. They are money oriented. It is a basic part of their personalities. They cannot change by themselves.

Our project, therefore, is to make economists quit being economists prior to the collapse of civilization. It is only by taking them outside of their economic world view that they can be shown how to imagine another world, a world without economics. We have to somehow show them the limitations of the boundaries of their world. We have to shock them into the realization that their world is a very small subset of reality.

My reply:

Asteroid: The English ’science’ has, since the late nineteenth century, been used in a new, weird, sense. Earlier, it meant ’studies.’ It’s counterpart in German (wissenschaft), French (science), and all other Indo-European languages mean ’systematic inquiry’ rather than something that deals with nature. Why the English term went off-track, I don’t know, but statements like ‘economics is not a science’ looks very weird to me (a foreigner). […]

What I see as the misuse of ‘science’ in English has irritated me for a while (and is related to The English Problem). It was then heartening to read Deirdre McCloskey‘s ‘The Rhetoric of Economics.’ On page 20 (second edition) and onwards she discusses and compares the use of ‘science’ to its counterparts in ‘all Indo-European languages.’ She also quotes Lord Kelvin, who in 1883 obiously helped make ‘science’ absurd:

When you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind […] It may be the beginning of knowledge, but you have scarcely in you thoughts advanced to the stage of science.

I conclude that economics is a science after all, only not in English.
