First, the basics:
- Convention (The topic of the book)
- The Analytic/Synthetic Distinction (Purportedly one of of the main motivations for Lewis's project in the book)
- Common Knowledge (Discussed in 2.1 (pp.52-60))
- Game Theory (For those [like me] who are game but don't know how to play it)
As far as I can tell from reading Ch.1, the kind of rationality at stake in this book is 'practical' (as opposed to 'theoretical'). Practical rationality is a central concept in what is classified as 'philosophy of action'. Some related entries are:
- Practical Reason
- Practical Reason and the Structure of Actions
- Weakness of Will (This refers to the problem of explaining why we sometimes act contrary to the better judgment we have)
Two more entries related to philosophy of language and philosophical logic:
Then there are huge survey articles on such broad topics as 'action' and 'belief', in case if anyone is interested...
