An exploration of the historical meaning of systemics in western thought.

Cybernetics and Systemics as new scientific tools for the study of complex issues and systems appeared and evolved during the 2nd half of the 20th. Century. This marks probably the beginning of a new phase in human mind's struggle to understand and if possible manage the world as it has been transformed by mankind itself during the 2nd Millenium. To discover the deeper meaning of the mental, psychical and social mutation in course, it seems important to reflect on the former evolution of western thought and its practical consequences. The historical period hereafter considered sketchily covers three main phases from the 11th to the 20th Century.
