Oh, please. The “Muslim world” was only ahead because it conquered advanced cultures - and then sucked the lifeblood out of them and lapsed back into its usual ignorance. Mohammed couldn’t read and in fact few of his people could; the later Koran wasn’t even supposed to be translated out of Arabic, so few people could read it.
When the Muslims swept over Spain, Sevilla was probably the most advanced city in Europe because Spain had been Rome’s most important colony and many of Rome’s thinkers, writers and even emperors were born in Spain. Several important early Church councils were held there, and in the 7th century, around the time that the illiterate Mohammed was attacking developed civilizations in the Middle East and only decades before the Islamic invasions had spread to Europe, St Isidore of Sevilla wrote a compendium of “all human knowledge,” which involved the sciences, Classical sources (those that had not been lost to Europe during the barbarian invasions), medicine, etc.
And Spain’s large Jewish population continued with its own tradition of learning, which led to the great doctors and medical practices that the Muslims then tried to claim as their own when they invaded. The only reason this learning survived as long as it did was that the invaders were fairly recently forcibly-converted Baghdadis and, later, Persians, who came from cultures that had been very advanced until they were overrun by the Arab followers of Mohammed. It seems to take about two generations for Islam to put out the lights in a culture, but in the meantime Muslims always take credit for the goods of that same culture that they are busy killing.
Where they had 2000 volumes.
In Cordoba - Al- Andalus- 150 years earlier - They had over 400,000 volumes -
With over 500 full time librarians. And the entire world, Christian, Jewish, and Muslim traveled there and studied together. In peace.
Is that what your talking about?
