Book review: Possible Worlds, Norman Swartz, Raymond Bradley, 1979
I could write a long detailed review but it is entirely unneeded. This book is without doubt the most enlightening book that I have ever read about logic, and it doesn't even cover predicate logic! So that says a lot. It is recommended for anyone who wonders if talk of possible worlds is really worth it, who wants a systematic introduction to propositional logic and modal propositional logic, and who is not afraid of symbols.
