Your insults and other ad hominem notwithstanding the positive evidence is available if you are gutsy enough to climb outside the cave and encounter it.
As to reason, are you serious about basing scientific theory on electrochemical interactions? Show me the research.
Like it or not, as some point you guys who are so wedded to a purist doctrine of naturalist science will have to give it up. Too much of naturalistic science is too biased in its philosophical and political assumptions to withstand the attack of reason.
And the "attack of reason" stems from the bible and religious belief, I presume?
so far I have not used ad hominem.
If you consider "IDiot" an insult - pity.
proof that reason is a product of electrochemical interactions in a cellular matrix can be (and has been exhaustively provided by) neuropharmacology, neurosurgery, neurotrauma, ECT, electromagnetic hallucinogenesis, etc...: Interfere with the chemical, interfere with the electrical, interfere with the cellular; "reason" is modified.
did you mean something other than the human mental faculty?
