The paper is an attempt of reconstruction of a few methodological assumptions of chosen representatives of the Cracovian school, eg. Adam Krzyzanowski, Adam Heydel, and Ferdynand Zweig. Even a brief presentation of work of these economists allows to notice differences among them regarding the subject of economics and scientific methods. For example, methodological assumptions of Krzyzanowski and Zweig are closer to classical economics, while the approach of Heydel is more in accord with neoclassical economics. Methodological differences among them were not a barrier for the Cracovian school to propose a common stand in regard to liberal economy assumptions.
