This e-book consists of research papers and personal reflections of Felix Geyer's work or to the areas in which he has been active (socio-cybernetics, alienation theory). Socio-cybernetics can be defined as “Systems Science in Sociology and Other Social Sciences” - systems science, because socio-cybernetics is not limited to theory but includes application, empirical research, methodology, axiology (i.e., ethics and value research), and epistemology.
