Mais-Valia ou Mais-Valor?

Abstract

This article seeks to analyze the reasons and possible consequences of an ongoing movement in the economic Marxist literature in Brazil that is the exchange of the expression mais-valia by mais-valor. Starting from the discussion made by Mário Duayer about the ontological character of Marx's critique, it is argued that the expression "surplus value" is more functional and adequate for the various interpretations of Marx's work. Rather than an analysis of the semantics involved in the change of terms, what is intended is to illuminate the ontological character of Marx's critique in the surplus value theory, bringing to light the impertinence and inadequacy of replacing, at this point in the debate, the expression of value added.
