Whatever part of the world or country or region you may call your own, the population you share it with got there largely as a result of mass migration. Most of Europe is populated by those whose ancestors took part in the major movements of Völkerwanderung, and populations changed and shifted through major major migration or conquests. No significant country you have ever heard of has had a settled population through the centuries. Nor is this all ancient history – it has been a feature of all centuries, to some extent at least.
One of the consequences of migration has been the internationalisation of learning. Even when there were hardly any efficient methods of transport, scholars and students wandered between centres of education and enriched each other’s cultures. Universities became knowledge exchanges of scholarship and cultures, influencing national development (of which Scotland, from where I write, is an excellent example).
Of course large-scale migration also poses challenges and requires the adoption of sensible policies to manage it. But the desire sometimes expressed in modern times for a recognisably uniform autouchtonous ethnic culture that has uniform traits is not at all an expression of tradition: it contradicts civilised human experience and has the capacity to align itself with tyranny.
Many of our recent global developments have their roots in the fear of migration: Brexit, Donald Trump’s wall, ethnic cleansing. These are not good developments in so far as they are driven by fear and insecurity. Politicians must address this with more wisdom than many have shown; but in particular they must recognise that scholarship and learning cannot thrive within closed borders. And the higher education academy must keep making the case for the shared international experience of the educational community.
