Following one of our research lines, we present here the first English translation of Social Parasitism in the Life of Nations, a work written by Arno Schickedanz representing an example of ideological purity. In the discussion section we make use of the herd analogy to describe social organization of some groups. Examples are provided and fully discussed. This approach is perfectly acceptable because Homo sapiens belong to the order Primates and certainly exhibit herd behavior under certain circumstances. This model is employed to show how a country can be colonized and manipulated.
