For as long as anyone can remember, the instrument of exclusion has been used to define who belongs and who does not. It was also a common mechanism for establishing an identity to attach negative connotations to other people and their views by excluding them. This becomes difficult with such larger groups as regions, nations, religions, parties, political movements, organisations, etc. Who is German? Who is a Christian, a Moslem, or a Buddhist? Where exactly do you draw the line? Such questions already indicate that the instrument of exclusion is fraught with frustration—at least for some people.
History has shown that the instrument of exclusion, taken to extremes, leads to murder, and is not a recipe for peaceful coexistence. It is a primeval instinct stemming from the reptilian parts of our brains. Today, we must see and integrate all of the aspects of the whole, doing exactly what exclusion does not want to do: attaining health and happiness by including everything.
