This article discusses the ‘Lachmannian dilemma’: a theory about spontaneous orders requires methodological subjectivism and the complexity of the allocative problem. However, the formal representation of the economic problem in the economic theory of complexity carries the risk of losing sight of the very appreciation of those elements. A way of overcoming the dilemma is given by an appropriate methodological interpretation of the theoretical concepts. In this sense, we argue that the Austrians are the followers of the classical methodology concerning que consequences of complexity.
