This article discusses the social tension provoked by what is known as the new fundamentalisms. In particular, political fundamentalism, market fundamentalism, cultural fundamentalism and religious fundamentalism, which, curiously enough, sometimes unite against the social compact of modernity. The breach of the social compact or commitment brings about a lack of submissiveness of the political power and the of economic power to the law. It is at this point in time that fundamentalist tendencies become more radical in their interpretation of political action and of economic action for example, dogmatic interpretations of democratic procedures or the totalitarian interpretation of the functioning of the capitalist free market, which go to the extreme of equating democracy ideologically with the market or, also, democracy with political and economic neo-liberalism. Moreover, there is a need to consider the increasing interference of religion and its churches in these secular fields, radicalising its religious message and bringing about severe ethical and religious clashes. This in turn reverses the very process of secularisation of the modern Western world, converting it into a new move towards religious confession abroad in the world.
