ABSTRACT
NEO-CLASSICAL economics in Britain is most conveniently dated from the work of Stanley Jevons. For it was he who first tilted the balance in value theory from cost to utility, applied mathematics to the supply and demand curves, and conceived the project of building with elaborate statistical material an exact science. This science he defined as “the mechanics of human interest.” There are not a few passages, especially in the opening chapters in his Theory, which show how near his mind came to a broader and more balanced statement of the utilitarian calculus than that which he actually took.
