A classic from Murray Rothbard (who also takes a well-deserved shot at economists /econometricians invading other fields):
In recent years, economists have invaded other intellectual disciplines and, in the dubious name of “science,” have employed staggeringly oversimplified assumptions in order to make sweeping and provocative conclusions about fields they know very little about. This is a modern form of “economic imperialism” in the realm of the intellect. Almost always, the bias of this economic imperialism has been quantitative and implicitly Benthamite, in which poetry and pushpin are reduced to a single level, and which amply justifies the gibe of Oscar Wilde about cynics, that they [economists] know the price of everything and the value of nothing. The results of this economic imperialism have been particularly ludicrous in the fields of sex, the family, and education.
So why then does the present author, not a Benthamite, now have the temerity to tackle a field as arcane, abstruse, metaphysical, and seemingly unrelated to economics as hermeneutics? Here my plea is the always legitimate one of self-defense. Discipline after discipline, from literature to political theory to philosophy to history, have been invaded by an arrogant band of hermeneuticians, and now even economics is under assault. Hence, this article is in the nature of a counterattack.
