From the book, Original sin:  A Cultural History (HarperCollins, 2008 ) by Alan Jacobs:

We have never had more need to explain ourselves to ourselves, but we manifestly lack the resources to do so.  It may be (I think it is) a propitious moment for reconsiderating that curious concept called peccatum originalis, the belief that we arrive in this world predisposed to wrongdoing–that this world is a vale of tears because we made it that and,  somehow, couldn’t have made it anything else.
