You may be right. However, this paper was written in 1991, and AFAIK
nobody in the intervening 17 years has yet come up with any way to

You may believe what you like, but the overwhelming empirical evidence
suggests that natural language is not a formal system of any kind. But
I would be delighted if you could prove this wrong, by demonstrating
that it is indeed a formal system. (01)
