I was called stupid today for saying it's not irrational to believe that a human's thoughts, personality, etc. are a completely physical phenomenon occurring in one's brain. I also said it's irrational to believe that one's memories and personality could stay intact when their brain stops functioning and rots away. I said "it's like saying a computer can work if you take everything out of it."
I sound like the typical ranting atheist, but seriously, god is a product of imagination. That doesn't mean it isn't real. It just means that it is not a phenomenon that can be verified by reason. Like all beliefs that are believed through socialization, personal desire, and evasion of rationality, the person believing it is going to believe that it is more special and more plausible than any of the same type. It's a proven psychological phenomenon. A person raised to believe in Zeus is going to think Zeus is as plausible as a person raised to believe in god thinks god is.
The problem I have is the infinite room for disagreement within imaginary concepts. Unlike other imaginary things like stories, gods have had civilizations and governments built around them. They have also been the driving force of division and massacre.
The cruelty of the Aztec empire largely stemmed from their belief that their gods lived on human blood. During the late era before they Spanish arrived they were going on a conquering binge. They were upping the amounts of sacrifice and the amounts of people they killed as they began to conquer more areas. They wanted Huitzilopochtli to bring them success in war. It was a cycle fueled from a simple imaginary belief that caused millions to die.
I should find friends interested in intelligent discussion that are not anarchist potheads.
