My own theory is that it had to do with the recognition of two worlds, mental and physical. I recall reading St. Augustine's Confessions, and I was surprised at what a big to-do he made about memory, at his power of replaying scenes of the past in his mind. This preoccupation led him to believe in an incorporeal God (before he found that impossible to believe--if God was real, he was corporeal). So the connection, you see, is between the incorporeal and the mental.
Since we have mentality, incorporeality is possible, so the thinking goes. In other words, the mental world is the spirit-world. Thus the birth of religion.
Would somebody tear this to shreds, please?
Thank you.
