Several years ago, while studying philosophy, I recall reading in numerous sources that Dennett believed (or was interpreted as believing - by either Clark or Churchland [or Fodor?]) that it was language that basically transformed the brain into a symbolic machine (to loosely paraphrase - the point was that language had a massively transformative effect on the brain [or mind, I don't care which he referred to]).
Unfortunately, I no longer have any of the books/articles that I was reading back then, so I can't go back and check them all. I've been searching online for a day now and have been unable to track down any of these sources.
Does this ring a bell for anyone?
