Religion, that globalising influence par excellence, constitutes the most powerful known factor of political, economic, social, and national integration. However, religion can also at times be a factor of disintegration ornon-integration, because of its historic vision. The lesions of millenarianisms prefigure the hopes, problems, failures and the illusions of society. Time has, in itself, an ideological dimension that varies according to the perception that one has of it: positive or negative, turned toward the past of the future, inevitably neutral or progressive.
