And Muslim Science was (partly) killed by one man and his insane philosophy of "Occasionalism". His name was Abu Hamid Muhammad ibn Muhammad al-Ghazali", an 11th-century theologian based in Baghdad. This idiot began the destruction of the greatest intellectual achievement of all human history: Science. He began the total destruction of Muslim Science that was completed by the Turkish invasion. Put simply, Ghazali denied the very foundation of Science: the principle of cause and effect.
