Unless you're a die-hard Quine scholar, I don't suggest this book. Dilham's critique is rambling and incoherent. The book is full of references which the reader may or (more likely) may not be familiar with. Much of the book seems unmotivated and directionless. He may very well have some valid points, but it's hard to tell, and it's not at all clear that it's worth working through this book to find out.
