Landmann’s fundamental anthropology answers the question of what is the source of various forms of humanity in history, what is the origin of the variability of historical images of man. A striking feature of this anthropology is, however, the search for what is fundamental, related to the spirit of Wilhelm Dilthey’s historical thinking. It leads to the discovery in man of historicity as his constitutive feature. Both of these alternative ways of understanding man from the point of view of either his historical changeability or the stability/continuity of his fundamental structure turn out to be reconcilable in the theoretical approach which Landmann proposes under the name of fundamental anthropology. In Landmann’s thought about man, human historicity/creativity is fixed and human nature is immutable.
