This is coolbert:
I had originally thought this was a case of jahhaliya. Islamic response to ignorance. Books and manuscripts from the time BEFORE Mohammad. But that is not the case.
"ISIS Burns 8000 Rare Books and Manuscripts in Mosul"
"While the world was watching the Academy Awards ceremony, the people of Mosul were watching a different show. They were horrified to see ISIS members burn the Mosul public library. Among the many thousands of books it housed, more than 8,000 rare old books and manuscripts were burned."
“If the books agree with the Qur’an, they are superfluous. If they disagree with it, they are heretical.” - - Omar.
Omar the Caliph from the time of Mohammad. The ISIL Salafists emulating those first three generations of Muslims.
We can think of the burning of libraries in the historical context during a time of war and conflict.
Alexandria, Baghdad, Louvain and now Mosul. That Great Library of Alexandria as set afire on a number of occasions during a time of war or conflict so it seems, that collection of original works from antiquity lost forever much to the detriment of all mankind.
