Erasmus isn't just an EU programme. It is an institutionalised expression of a genuinely modern phenomenon - travel abroad for the sake of it. #Erasmus#Brexit
In this sense, the emergence of Erasmus marked a historical continuation of an increasingly more common practice, which - much like higher education itself - had once been the privilege of the elite few.
Clearly, neither Erasmus nor today's higher education, in Europe or elsewhere, are bastions of equal opportunity. However, Erasmus has always been an effort in that direction.
Yet in many ways, today's events are reminiscent of the historical circumstances which gave rise to what is often considered the forerunner of the Erasmus programme - The Grand Tour.
Do, for example, self-citations from one's own preprints also count? There are scholars with huge Google Scholar citation count because they self-cite a lot, but when you look them up on Scopus, they practically don't exist.
There are also people who cite only celebrity scholars because they think that's what will make them look smart.
There are people who cite mostly stuff published in recognised journals because they think that's more reliable, "proper science". Plus, some are lazy.
Some cite what others cite without even reading the cited source. If you don't believe me, ask Meyer & Rowan 1977 and Powell & Dimaggio 1983.
Some folks cite tend to hyper-cite their friends and colleagues. Or editors of the journal they publish in.
