This article is devoted to the understanding of an economic science known as "humanity". In an economic science, a problem of economic interpretation is rather significant: it investigates the importance of economic concepts and statements. The American economist D. McCloskey has criticized the modern economic science from positions of economic rhetoric. The economic rhetoric of D. McCloskey criticizes economy for neglect objectivity principles, an inattention to the text that has "implicit" and "personal" character of economic theories and hypotheses and considers economic science as a special case of literary criticism. In practice, this criticism repeats already known conclusions of M. Veber, M. Polani, P. Feyerabend and other known methodologists and only contains ascertaining of the fact that the economy also is "humanity".
