Why should non-believers not have access to that knowledge? You can understand another's viewpoint without sharing it.I'd be interested in hearing too, Scott.
However, I have to add that I am always intrigued that non-believers claim to know so much, and with such certainty, about why people believe, what they believe, how they believe, how they should behave, and so on. That endless yadda of I-believe-what-I-believe-and-you-should-too is as boring in one direction as it is in the reverse direction -- and from Dawkins, especially. At least to me.
The difference is that Dawkins provides facts and reason to explain why he believes what he believes.
