The paper describes that period of the Hungarian philosophy, in which it became professionalized, namely the Kant argument, which was the first step the Hungarian philosophy took towards its being public. The question has to be answered whether Kant’s thought could become a part of it. Due to political developments as well as the pressure of the church the turn of the century witnessed the shift from epistemology to the issues of moral philosophy and theology. Thus the conditions for the reception of Kantianism and post-Kantian philosophy in the 19th century have been created. The fundaments for the development of axiology were laid as well. The paper covers the main phases of the debate with their leading representatives.
