What I admire most about the author is the honest search for Truth. It is a rare individual that can approach this problem while relinquishing their biases. I can't count myself among their ranks. It seems the majority of people, believers and non-believers alike, tend to come to a decision about God after about an afternoon of thinking about it, at most.
And really, what philosophical question posed to us could be more important than the question of God? It seems that every human should spend some significant amount of time deciding where they fall on this problem before they do...well...anything else.
