While this singular event obviously falls short of proving anti science attitudes fully prevailed, it is generally agreed that "the Islamic world" in 1900 had less scientific knowledge compared to in 1200, when the majority of their citizens weren't even Muslims. As the ideology permeated more and more of life science (ie. Books and courses) retreated and were rewritten again and again to fit the ideology better. Everytime something was lost. Over time a lot was lost. Even though Islamic did not quite destroy science it certainly destroyed the essential part: where science and religion conflicted, there was no additional investigation, no reconsilliation, no compromise. They chose for the utter dominance of their ideology, and anything even threatening a contradiction was destroyed, if necessary including the people behind it. This is in fact not weird but rather the common choice of societies. The Vatican is unique in the fact that it paid considerable numbers of people to find and study things contradicting Canon, for centuries. It should be said that their attitude to contradictions outside of their institutions was very different. The theory may have been that with enough research the contradiction would be revealed not to exist. Many say this is the result of the classical Greek heritage of the church.
