A methodological approach to economic action

The discussion of economic action at the level of economic schools is one of the most vital topics that every economic school necessarily has a view on. For this reason, in a comparative study, we have traced the position of this debate in the capitalist and Islamic economic schools. In this regard, the main goal is to examine the theoretical accuracy and negation quality and to prove the propositions needed to prove the theory of economic action. This discussion connects us with the big issue under the title of presuppositions of scientific approaches that there is a methodological ambiguity in how to prove them in the history of science. In this article, by reporting and evaluating the basic theory in the Austrian school and the Islamic school, we showed the similarities and differences of these two theories at the content level and at the method level. In this review, it became clear that this basic theory in Islamic economics fulfills the epistemological ideals both in terms of content and method, which is not available in the Austrian school. This theoretical ability is a result of the methodological unity and comprehensive global view that the Islamic ijtihad approach has towards knowledge. A methodological unity that also opens up the historical ambiguity of science regarding the way of checking the assumptions.
