Nothing explains Islamic modernism, the whole rush to Islamic banks, the Islamic state and Islamic democracy, etc., more clearly than this passage by Ibn Khaldun. :
22. The vanquished always want to imitate the victor in his distinctive mark(s), his dress, his occupation, and all his other conditions and customs.
The reason for this is that the soul always sees perfection in the person who is superior to it and to whom it is subservient. It considers him perfect, either because the respect it has for him impresses it, or because it erroneously assumes that its own subservience to him is not due to the nature of defeat but to the perfection of the victor. If that erroneous assumption fixes itself in the soul, it becomes a firm belief. The soul, then, adopts all the manners of the victor and assimilates itself to him. This, then, is imitation.
Or, the soul may possibly think that the superiority of the victor is not the result of his group feeling or great fortitude, but of his customs and manners. This also would be an erroneous concept of superiority, and (the consequence) would be the same as in the former case.
Therefore, the vanquished can always be observed to assimilate themselves to the victor in the use and style of dress, mounts, and weapons, indeed, in everything.
In this connection, one may compare how children constantly imitate their fathers. They do that only because they see perfection in them. One may also compare how almost everywhere people are dominated (in the matter of fashion) by the dress of the militia and the government forces, because they are ruled by them.
This goes so far that a nation dominated by another, neighboring nation will show a great deal of assimilation and imitation.
