If you want a history of the debate between skeptics and believers told essentially from the believers' point of view, this lecture series does a good..Show More » job. My impression is that Professor Roberts includes just enough of the skeptics to show how they affected the arguments of the believers. But if you're looking for a robust summation of Hume, Nietzsche, Marx, Freud, etc. presented with an emphasis equal to that given the other side, this is not it. In fact, I'd say it's at best 1/3 skeptics and 2/3 believers.
At the very least, the title of the series is misleading. It might have more appropriately been something like: "Religious Debates in the Western Intellectual Tradition: The Response of Believers to their Critics." But then, I would not have purchased it.
