To these self-confident researchers, the idea that the spirit might exist apart from the body is just ridiculous. Instead, everything arises from atoms. Genes shape temperament. Brain chemicals shape behavior. Assemblies of neurons create consciousness. Free will is an illusion. Human beings are “hard-wired” to do this or that. Religion is an accident.
In this materialist view, people perceive God’s existence because their brains have evolved to confabulate belief systems. You put a magnetic helmet around their heads and they will begin to think they are having a spiritual epiphany. If they suffer from temporal lobe epilepsy, they will show signs of hyperreligiosity, an overexcitement of the brain tissue that leads sufferers to believe they are conversing with God. ~Brooks
I think the real problem here is that these people really think that there two irreconcilable viewpoints, but I don't see it that way. One model says that angels and demons shape temperament. The other say it's genes and/or experiences. What we used to called 'angels' and 'demons' are now called 'genes' and 'experiences'. One side feels that the other side was using outdated and ambiguous concepts. But have they really examined the concepts of genes and experiences enough to prove that those concepts are not likewise ambiguous and fanciful? The other side feels that their glorious hierarchy of personalities has been reduced to a blind and soulless mechanism. Have they really explored the properties of genes and experiences in enough depth to justify such prejudice?
