Overall, a very lucid and readable book. Armstrong's case is primarily built against the newage militant atheist as well as postmodern religious fundamentalist but in doing so she obscures further - perhaps inadvertently - the nature of ultimate reality we call God.

She successfully traces back the roots of post-renaissance apophatic theological shift in antiquity and medieval religion. However, her version of God presents another problematic of reducing God to a mere abstract symbol or a set of symbols. In my humble view, Armstrong's thesis is apt to question a theist's conviction as much as it helps in countering the thesis of an atheist.

Any one interested in broad historical currents of theological metaphysics related to God must not miss it. Perhaps better than many of Armstrong's other books as far as asking the right questions is concerned, but if you are thinking to counter Dawkins and Hitchens, Armstrong's case is not more than a starter.
