This review is from: Modal Logic as Metaphysics (Hardcover)
Do not try to read this book without a strong background in modal logic and set theory - it is very technical, to a level that I am certainly not qualified to judge. But, in addition to a being a rigorous introduction to the mathematics of possible worlds theory, it also states a philosophical case - that if this theory is taken to be a good model of the world (or worlds) then it has strong metaphysical implications, notably that a lot of things that appear to be contingent are actually necessary. But this is a bit like arguing that apples fall out of trees the way they do because of Newton's calculus. It is the other way round: the maths (in that case) does a good job of modelling the world. If the apparatus of modal logic and possible worlds really requires us to believe things that seem counter-intuitive, we might be better off to treat them as being mainly of mathematical, rather than of philosophical, interest.
