The Value of Religion in a Scientific Age.

In a Scientific Age is Religion a Hereditary Delusion? - Beliefnet :

"The spiritual, actually religious component, of human history contains much of value in how to get along, or not, with your fellow humans. But where it becomes a delusion in a scientific age is when it becomes a Belief System, all of which must be adhered to and the God worshiped, feared and obeyed. I find it interesting that Progressive Christianity, in denying the God mediators in favor of the direct relationship of people with God, has largely abandoned the Belief System of Christianity, and is learning from the social truths that are an integral part of Christian history."

Including most particularly the myriad lessons on what doesn't work. One could build a pretty decent life just not doing what religions did for most of their existence.
