This paper tries to understand and disambiguate the concept of the Philosophical Anthropology in scope of the thought, as Mengüşoğlu tries to explain by putting Kant and Scheler philosophy at the center. Mengüşoğlu states, in his own studies, what kind of method shall be followed while doing this, and he does it based on the phenomena, actions and freedom concepts starting from the holism approach. In other words, it aims at discovering an interdisciplinary field that can extend from social psychology to ethics, by examining the theoria, praxis and poiesis fields as Mengüşoğlu does. The actions and phenomena concepts were tried to be explained in scope of holism displayed together with the field of existence and values, of the perception processes that bring thought and action fields to the people. The way the philosophy methodology is used in scope of the social sciences by Mengüşoğlu, who puts people's capability/ability states at the center, makes possible the culture of discussing the interpretable relativities in a historicalness consistent with each other. This paper also aims at examining this consistency's ontological foundations.
