Ok a people do great things. They build wonders, they form great civilizations, they make great advances in science, arts, law, etc. So please tell me of the great things the Arabs have done.
Ok a great people do great things
I dispute that the only value of someone's cultural worth is whether their civilization has advanced global culture. What about primitive tribes or Native Indians? Are these people worthless?
Plus, I could reengage this debate about the cultural advances of the Ottoman Empire and previous advances in medicine, mathematics, and retention of classical learning, but there's little point.
