Arnie has been on a flying visit to Cambridge. Always very good to see him — and great fun to go out for a long evening of wall-to-wall philosophical gossip at the excellent Riceboat. One thing which I hadn’t registered which is worth passing on: Arnie’s A Structuralist Theory of Logic is now available as a paperback. It’s still not exactly cheap, but I do hope it gives the book another lease of life, as it deserves a higher profile than it has had. At least make sure it is in your university library!
