The Universe is unique and diverse. The truth is also unique and diverse; it is outside and inside us; but it changes with time. The humanity lives more and more in our global village. The European, Assiatic and African civilizations ignored the American civilizations up to modern age. Their truths were not “contaminated”. With the cultural interchange they start to consume potatoes and tobacco; much earlier they started to commerce with skins, species, porcelain and silk. In our global vollage the standarization is a imperious neccesity. How else the airplanes of all the countries could land in every airport of the World? How else the containers of all companies could be carried in every port of the World? Nevertheless local truths survive everywhere, but we must distibguish the picturesque or even necessary as music, costumes, addresses, alimentary habits; from others that make our lives not very easy because they behave as barriers to the human performance.
