The rationality principle as a universal grammar of economic explanations

A universal grammar of economic explanations is characterized by the means end :rationality principle, which can be understood by drawing a conceptual distinction between its two facets: theoretical abstraction and empirical content. The former serves as a pure form of economic way of thinking and thus delimits the capacities of economists to perceive and understand the :mani fold human behaviour. latter provides econom:ists with objects of thought and renders the discipline empirically relevant. Given the implications of the two facets of rationality, the main task of economics as a descriptive science is to incorporate appropriate empirical content into the pure rational framework with the aim of better explaining and predicting human behaviour. As a prescriptive science, economic inquiry should draw on the persuasion and communication skills of its practitioners, thereby influencing the state of the economy through changing the :means and ends of the decision makers in question.
