(B) If the discipline of linguistics has so little to be said in its favour, one might wonder how it continues to flourish as widely as it does. It was never the case that all universities contained a linguistics department, and there are probably fewer of them today than there were in the immediate aftermath of the 1960s wave of enthusiasm. But the many linguistics departments that still exist are fairly secure. In the 21st century, decisions about which subjects should be offered in a university are made not in terms of their intellectual solidity but of which will be cost-effective, by attracting a market of student takers. Linguistics departments are well placed there, for two reasons. (Sampson, Geoffrey. 2017. The Linguistics Delusion, Equinox)
