…in the past ages a common language shared by various nations created a spirit of solidarity among them. For instance, 1300 years ago, there were many divergent nationalities in the Orient. There were Copts in Egypt, Syrians in Syria, Assyrians and Babylonians in Bagdad and along the River Mesopotamia. There existed among these peoples rank hatred, but as they were gradually brought nearer through common protection and common interests, the Arabic language grew to be the means of intercommunication, and they became as one nation. They all speak the Arabic language to this day. In Syria if you ask any one of them he will say, "I am an Arab," though in reality he is not -- some are Greeks, others Jews, etc.
