Ex Oriente Lux? Ex Occidente Lux?

To be disoriented is a clear and common expression, though it seems not to have been applied as creatively to culture, societies and history as it might.
As there is a "disenchantment" found in the history of the modern world, and secularization, one might say that there has been a disorientation from the sources of the "West", which originated in the East (ex oriente lux). But if there is a kind of cultural sun-setting of the West in the globalizing, "post-modern" world, then one could say that there is a disoccidentalization ongoing.
