Mathematics and Economics - Norbert Wiener

The success of mathematical physics led the social scientists to be jealous of its power without quite understanding the intellectual attitudes that had contributed to this power. The use of mathematical formulae had accompanied the development of the natural sciences and become the mode in the social sciences. Just as primitive people adopt Western modes of denationalized clothing and of parlamentarism out of a vague feeling that these magic rites and vestments will at once put them abreast of modern culture and technique, so the economists have developed the habit of dressing up their rather imprecise ideas in the language of the infinitesimal calculus ... To assign what purpots to be precise values to such essentially vague quantities is neither useful nor honest, and any pretense of applying precise formulae to those loosely defined quantities is a sham and a waste of time.
