Yeah I was confused on that. I have Reasoning and the Logic of Things and knew the delivery date. But the introduction for the CP 6 put the date as earlier. So I started to think it was a preliminary text. (I’m at work so I don’t have access to my library - I usually prefer to quote from EP 2 or RLT rather than CP for reasons like this. (It’s just a pain to figure out the dates - although perhaps that’s me) Thanks for clearing that up. That explains why it’s so modal realist. > Is there a plausible way to integrate the two mentions of a blackboard into a > single diagram?

Yes I think this is right. It gets at the issues we’ve been discussing. Although I hasten to add I’ve not read the full exchange from last week yet.
