In 1996 my book 'The Nature of Cultures' appeared in Vi- na and New York. It describes cultures as systems which are controlled by MSC and decorum. While MSC is a neologism meaning 'maximal stress cooperation' decorum is a very old term. It is as old as Western culture itself, and is furthermore, the translation of the even older Greek word 'prepon'. Decorum and prepon mean 'to be suitable, to be fitting'. It is all about the fitting of cultural medial contents to elementary cultural behavioural types and behavioural phases. These behavioural units are subject to a type of ranking system in which that which is essential is sorted from that which less essential. - corum then means - the representations of the media must 'fit' the ranking of the cultural behaviour. It is MSC which assumes the top position in this ranking. In 1996 and the two previous years when I was working on my book 'The Nature of Cultures' less than 5 years had passed since the Iron Curtain had been lifted. Many believed at that time that with ending of the Cold War, which was more or less de facto peace anyway, that a new and better age of peace was dawning.
