How can we establish new institutions and practices in order to use fare-free public transport as a beacon for sustainable mobility and a low-carbon lifestyle? The author of this essay elaborates on how practice theory and institutional economics can help to answer this question.

From the two premises that (1) economies are complex systems and (2) the accumulation of knowledge about reality is desirable, I derive the conclusion that pluralism with regard to economic research programs is a more viable position to hold than monism. To substantiate this claim an epistemological framework of how scholars study their objects of inquiry and relate their models to reality is discussed. Furthermore, it is argued that given the current institutions of our scientific system, economics self-organizes towards a state of scientific unity. Since such a state is epistemologically inferior to a state of plurality, critical intervention is desirable.

The article pursues the two related questions of how economists pretend to know and why they want to know at all. It is argued that both the economic form of knowledge and the motivation of knowing have undergone a fundamental change during the course of the 20th century. The knowledge of important contemporary economic textbooks has little in common with an objective, decidedly scientifically motivated knowledge. Rather, their contents and forms follow a productive end, aiming at the subjectivity of their readers.
