book's page on the Wiley site you can actually read a page proof of the first chapter - see over on the right-hand side of the screen.
This should give you an idea of whether the rest of the book might be of interest to you, or someone you know, or your local library or educational institution. Getting to read the entire first chapter will give you a more in-depth grounding in what the book is really all about, and the kinds of arguments that I am going to use, than anything I could possibly say here. So please consider having a look.
You can also see the table of contents and the index, which will give you an even better idea of what is covered.
Also, if you live here in Australia ordering straight from Wiley's site might be as easy a way as any of getting hold of the book at a reasonable price (if you create an account with them, you can also use it to buy other interesting books in the Wiley-Blackwell philosophy range). I've gotta say, though, that for American readers there's really no substitute for the very good pre-release price that Amazon is still offering.
