Nice. Apparently Putin is willing to quote from bigoted 'right-wing' sources (americanthinker.com) that he would ordinarily turn up his nose at and condemn anyone else for using. Ain't hypocrisy great.
"All of this is false."
Bullshit. You should stick to preaching the glories of the Marxist ideal to your defenseless undergrads and leave history to the historians. There's a reason you didn't pull this crap from any kind of reputable source.
"Anyway, your Muslims declared scientific materialism to be 'unlawful'"
As do other religious traditions (aside from the Marx cult, of course). So what?
Your first long cite is full of crap and unworthy of response. Your second quote is from Bernard Lewis, who you should know (but apparently don't) is very controversial. I will address it, however, out of respect to Lewis:
"We know of no Muslim scholar or man of letters before the eighteenth century who sought to learn a western language,"
First off, the fact that Lewis did not know of any doesn't mean there weren't any. The lack of knowledge of western languages is largely because Muslims scholars and men of letters had no need to learn a western language; the flow of new knowledge and information was flowing from Islam to the West, like the Canon of Medicine written by Ibn Sina (Avicenna) in the 11th century that was still in use in western medical colleges in the 19th. Muslim rulers, however, did see a benefit to learning western languages - as we learn a few pages later:
"Mehmed II, the conqueror of Constantinople, is said by a contemporary Venetian visitor to have spoken Greek and Slavonic, as well as Turkish. He is also said to have entertained Italian humanists and shown interest in their work, and is accorded by his Greek biographer the title of philhellene."
It is becoming increasingly obvious that Putin is just a troll with a lot of free time and some googling skills.
