Abstract
The aim of this paper is to clarify the Niklas Luhmann's frame of analysis of the modern west-european societal change from the perspective for the changes of historical-cultural products and its conditions. Luhmann thinks that the main phase of the modern societal change is the transformation from stratified differentiation to functional differentiation of the societal system. His hypothesis is that the increase of the complexity was the main condition for the changes of historical-cultural products which control communications. This hypothesis is based on his own social system theory. The term “Semantik” implicates a critical connection with accumulated studies of Historical-semantics in Germany. This paper, considering this connection, tries to clarify the Luhmann's frame of analysis of the modern “Semantik” changes as a frame of historical sociology of knowledge.
