Michael Lockwood is one of my favorite philosophers, but this is not his best work. Mind Brain and the Quantum was real philosophy AND real science. Mostly this is a "guided tour of the universe" type of book that goes way too quickly over the philosophical issues and takes a "science says" approach. There are some places where Lockwood is critical of stuff like the block universe and Everett interpretation of QM, but there's far too little of that. Basically for him it is one big (predetermined?) multiverse in which however many ad hoc dimensions and devices will be added until the whole thing works out mathematically. But shouldn't philosophers question such things instead of being apologists for the physicists (who don't need it anyway)? Verdict: philosophy as science popularization, but well done nevertheless.
