Imagine updating Hobbes' view of religion in light of contemporary neuroscience, linguistic analsyis, and anthropology and you can see the value in this book. Things missing include the work of Roger Penrose and others applying contemporary physics to the mind and what connection there might be in that with issues typically associated with religious concepts. This book does not attempt to demonstrate that there is no connection between the human mind and what might be considered the divine or spiritual. It simply evaluates issues associated with religious concepts especially in light of the Wittgensteinian rules and language games played in those contexts. It is more along the lines of James' "Varieties of the Religious Experience" in this respect. This book makes a great companion book to "Why God Will Not Go Away".
