Most people who care about such things probably are thankful to the Arab world for maintaining and curating The works of the ancient Greeks prior to the Renaissance. I know I'm thankful to the Arab world for doing that.

Unfortunately, a lot of people have a pretty narrow view of things like ownership and cultures, and the concept of knowledge as something collectively owned by the human race that happens to be in the hands of a certain group at one moment is difficult to conceive, especially for those who don't like whatever group happens to have it.

As long as it is accessible to the world, I don't really care whether the first person curating a certain piece of global history is from beijing, baghdad, or bath.
