Ghaffar Hussain reminds us that historically Muslim societies were much more open to scientific thought than they are now:
So why didn’t these ideas take off and integrate into the fabric of mainstream Muslim thought and society? There are a number of reasons.
Firstly, Muslim empires in the past believed in centralising knowledge rather than disseminating it en masse. Centres of learning, such as Baghdad and Cordoba, had their houses of knowledge in which scientists would work, preserving and developing on, primarily, Hellenistic knowledge. There was no printing press, and even when it did arrive it was rejected, thus such knowledge was largely reserved for an elite audience. When centres of learning were conquered and destroyed, as Baghdad was in 1256 by the Mongols, most of the knowledge was lost too.
Secondly, the religious authorities of the time were largely opposed to ideas being put forward by scientists and other rationalist thinkers such as Ibn Rushd, and before him, Ibn Sina. They felt threatened by non-theological attempts to ascertain truths and Muslim leaders often sided with the religious authorities for political reasons.
Thirdly, literalist and dogmatic strands of Islamic theology have been aggressively promoted all around the Muslim world over the past few decades or ever since huge oil deposits were discovered in the Arabian Gulf. The Saudi state, in an attempt at cultural imperialism, has done its best to mainstream Wahabi thinking in Muslim communities everywhere. The result: a retardation and stagnation of thinking in parts of the world that were already very stagnant.
