The Brain Drain: An Age-old Problem.

The article discusses the brain drain problem in Europe due to the migration of the scientists. Between the reigns of Justinian and Charlemagne, evidence of migration can be found by the learned and attempts to influence it. More signs appear from the beginning of the Benedictine era when European education and erudition was centered in monasteries or Episcopal schools. However, the first original documents on official policies that promote or prevent the migration of researchers appeared after the coming of European universities. Despite political fragmentation in the country, its intellectual and cultural unity facilitated migration which was caused by economic, political, social and intellectual advantages gained by acquiring knowledge in medicine, theology, and philosophy.
