Robert McCrum has published it in the Observer, here. If you've forgotten, McCrum is the author of Globish: How the English Language Became the World's Language. I would note that many people actually trained in linguistics are far from convinced that McCrum knows enough about linguistics to talk good sense about it. (For one example, see here.)
The piece is headlined "Language alters how we think" and it's about Guy Deutscher. The opening continues:
In his new book, Through the Language Glass (Heinemann), he fearlessly contradicts the fashionable consensus, espoused by the likes of Steven Pinker, that language is wholly a product of nature, that it does not take colour and value from culture and society.I have no comment at this time.
