It is altogether impossible for me to comment on all, or even on most, of the issues brought into focus and woven together so masterfully by Professor Putnam. Having been a close Putnam-watcher for quite a few years, I cannot cease to marvel at how Putnam takes, say, a mere technical point in logic, or a seemingly simple story (such as the story of the two Ruritanian children), and uses it like a magician's wand to invoke a whole host of fundamental problems in philosophy. Then, by twirling his wand — that plain example he uses — he forces those philosophical mammoths to change, transforming them in front of our gaping eyes. I think we have all learned a lot today. Before I say anything else, I would like, then, to thank Professor Putnam for the rare intellectual experience he gave us.
