Difference is that those ideas that you are referring to were not simply replaced carte blanche with Islam. Attaturk simply found an ingenuous way for Western politico-philosophical concepts to coexist in a system where Islam remained the bedrock of Turkish society.I was referring to Ataturk's kemalism which is based on the western values of democracy and secularism. These ideas took hold of Turkey, a "muslim land", though it has taken steps back in recent years.
If Allah wasn't taken seriously in Turkey, it wouldn't be a "muslim land" anymore, would it?
Muslim governments during the medieval times/Islamic golden age operated in the same fashion. The Arabs, given their geographical domination of the Middle East, were able to borrow from both the East and West and create a civilization that allowed them to reap the benefits of worldly gain and influence, but still retain their celestial roots.
This is very unlike the Christian West (especially Europe), where the original bedrock of civilization- Christianity- had to be competed demolished of, and replaced with an entirely new paradigm- that of Reason.
