My take on Campbell's work is not so much that we feel the need to invent God, but that we are constantly struggling to find a set of meaningful symbols with which to converse on that which transcends all symbols. These symbols change thru history but the topic of discussion has always remained the same, because we face the same life-cycle today, that man has always faced.<quoted text>
I listened to Campbell's " Hero With a Thousand Faces" many years ago on CD, lasted for months because I constantly had to replay it to try to understand all that was being relayed.
I'll give "Masks" a try.
It is amazing how myths and folklore seem to validate that Voltaire saying;
"If God didn't exist, it would be necessary to invent him".
A couple of interesting points from the Middle East,
Herding cultures come in from the northern steppes and from the deserts to replace planting cultures, here is where the Male-centered god replaces the earth-mother goddess (a different emphasis and culture).
The Hebrews were late on the scene, they adopt and modify the stories that already exist in the areas they move into. A common motif is that of the younger brother who is favored over the older. It can be seen in the tale of Cain and Abel, where Abel is the younger brother, a herder, and whose offering is pleasing to God (this tale also justifies any strife towards the old planting religions).
