You could hardly call Islamic civilization "lost" - not in the sense of fabled Atlantis, for example -- but few people today know very much about it, or are even conscious of how many aspects of Western society owe their very existence to Islamic roots.
In some way, we all come in daily contact with microchips, space travel, medicine, physical sciences, mathematics, engineering, music, literature,arts, architecture, and spirituality.Wow. It's amazing how they managed to come up with all that super-advanced stuff, given that most Muslim nations are despotic backwaters and not exactly on the cutting edge of anything other than machete sharpening. Do you think maybe the CC editorialist was mixing up Muslims with some other people?
But do any of us – including contemporary Muslims themselves - fully realize how directly all of these advances and disciplines have been built upon more than a millennium of achievements by Muslim scientists, scholars, engineers and artists?
