Interdiskursive As-Sociation

What is it that prompts a basically heterogeneous set of members to form into one as-sociation with a single programmatic aim? Why can the equally heterogeneous artistic products by those members still be perceived as a 'wholehard' socio-historical facts pertaining to these groups to the 'soft' aesthetic structures linking the various different programs and works at the intersection of the common interdiscursive elements common to them. The model is exemplified with reference to the period 1843 to 1924 and the following societies: -Glocke-, -Bergwerk-, -Sturmerkreis-, -Charonkreis- and -Werdandi-Bund-."
