The Illness and The Cure
A website called Connaissance de l'Islam has a substantial section devoted to a book entitled Islam and the Psychology of the Muslim by André Servier published in 1923 by Augustin Challamel. Here is a brief passage from Chapter XI. In just a few words he speaks volumes. Though he makes no analogy it is difficult not to compare the effects of Islamization to an illness.
Since the same causes produce everywhere the same effects, the various countries conquered by the Arabs followed the example of Spain and worked towards dismembering the (Arab) empire. In Persia, in Mesopotamia, in Egypt, it was nationalist feelings more than anything, awakened by foreign domination and strengthened by religious persecution, that spurred the people to revolt.
This movement for independence reveals a remarkable fact, already noted with regard to Spain: the regions that fall into barbarism under the Arab yoke, return to civilization as soon as they recapture, through emancipation, their freedom to think and to act. It is stunning proof of the nefarious influence exerted by the Arabs. As soon as the Muslim doctrine - a secretion of the Arab mind and a faithful expression of the Arab nature - triumphs, there is an intellectual paralysis of the people on whom it is imposed. Likewise, as soon as this doctrine experiences an eclipse, the people, released into the free inspiration of their nature, escape from barbarism and are reborn into civilization. The history of all the provinces that revolted against Arab authority illustrates this thesis.
