Economics and economic policy

The article is trying to introduce and defend the thesis that economic policy way not follow the theoretical foundations of economics but the development of economic theories from a number of reasons rather follows the practical outcomes of their "application" in economic policy than the opposite. The major criterion for the evaluation of an economic theory is it's success (or failure) when it can be seen as if it was "applied", i.e. only the potential of the application legitimises the economic theory (in opposite to "the empirical legality" in natural sciences) to becomes a popular and respected part of our scientific knowledge. Such an argument can provide, together with other methodological characteristics, an original insight into the evolution of economic knowledge from the point of view of the philosophy of science as well as it may serve for a self-reflection of the current state and method of the economic research.
