This article discusses Léon Walras’s conception of pure science, which naturalizes market prices. We then show how Marx critically explains the naturalization of economic phenomena in general. Then – based on Jacques Lacan’s theory of the subject – we indicate how the discourse of positive science contributes to the formation of technoscientific knowledge and, specially, to the diffusion of the neoclassical theory. Moreover, the article shows that this understanding of knowledge contributes to deduct from the responsibilities of technobureaucrats for potentially disastrous consequences of the application of positive science to society.
