In the early economic writings economics is seen as an efficient tool to commit moral values. Nevertheless the modern interpretation of classical economists uses their ideas to line up a moral-free economic theory. In this way the modern interpretation of classical economic theory is based at least on three fundamental misunderstandings: first a historical misunderstanding, i.e. the belief, that classical economic theory is a result of a development from moral science to economic science, second a theoretical misunderstanding, i.e. the assumption, that classical economic theory is designed as a model for social
structures in whole society, and third a conceptual misunderstanding, i.e. the opinion, that classical theory has sketched a normative ideal that should guide political rules. It can be shown, that none of these interpretations is actually based on classical theory.
