Being at the semantic extremes of empiricism, the terms of ethnocentrism and interculturalism seem antinomian, at first sight. The European construction philosophy excludes the idea of acculturation, although the elevated unit of community bodies tends to remove the economic, legislative, educational differences, logically followed by the cultural, religious or ethnic unit. Reserving the ethnic specificity, especially the small groups, some in danger of being assimilated by the majority, is a part of the official EU policy, which does not mean that the phenomenon of acculturation is not following its course towards annihilation. The new mobility in the European area is not at all favorable to the ethnic specificity, which stimulates firstly the multiculturalism in order to achieve ultimately the interculturalism. A Europe of nationalities that preserve indefinitely its specificity is nonsense; the multicultural one is an endless source of tensions and conflicts, stimulated by recent history and conservative mentalities, while the intercultural one seems to be still a utopia. Without interculturality, the European communitarianism has no chances of survival, no matter how many constitutional or legislative concessions would be on behalf of the national states.
