Another thing was that linguistics had been a very meat and potatoes type subject, looking at texts in a rather dull way, but here was this guy writing stuff such as 'Cartesian Linguistics', which has the sub-title, 'A chapter in the history of rationalist thought', and also slamming behaviourism. In fact, he came in for heavy criticism for this stuff, but it didn't matter, he had declared war on behaviourism, and raised the flag of mentalism and nativism, and for various reasons, partly political, young academics flocked to his standard at MIT. Well, he was glamorous. I went to a talk of his in London, and the queue to get in went down Euston Road. It was fun, although most people there probably didn't have a clue what recursion is.
I was remembering a research project getting young kids to repeat sentences with recursive structures, such as 'the rat the cat caught is dead', and below a certain age, they can't do it, and then it clicks (about 7?). Of course, the big argument was whether this was purely linguistic or cognitive, and Yer Man said the former, whereas Piaget had said the latter.
