I wish I had a name to go with the ZMan’s blog, but he seems to be in business around DC, and having done that myself, and having read how forthright his writing is, I understand.
This is an example, arguing that you/we can’t understand the present without a firm understanding of the past, and like it or not (that’s mine, not his, interjection) that’s largely Western Culture’s history (and now we’re back to his thesis) and Western Culture’s history can’t be understood without knowing religion, and specifically Christianity (and Judaism and Islam, but I just want to refer you to his article, not write a precis).
I’m familiar with most of his suggested sources, and agree that they’re the best way for an athiest/agnostic/lapsed member to start.
Read it. Please.
