Well, most things we learn are adaptive -- the common arguments with the common replies... we learn how to express what we already believe like experts... we learn where the tire ruts are and follow them.
But to suggest something of the ironic in order to add zest to this thread, I have found that the Atheists lean heavily upon their own Doctrines which are never to be examined. I've even seen it admitted to a few times, where the use the term PRIMA FACIE, ordinarily referring to the rules of legal evidence, in this case in reference to evidence too plain and obvious to be subject to review. Well, it seems that Science has defined a set of its own Prima Facie, that it takes as Granted. Some of it makes sense -- the Newtonian Laws of Physics and Conservation of Energy, but their Prima Facie Case is endlessly extended through infinitely multiplied correlaries so that it is fairly stated among them that NO RELIGIOUS ASSERTION CAN EVER BE TRUE. So it is that all observation and anecdotal observation is instantly dismissed from sheer Prima Facie Assumptions.
There was the case of Prahlad Jnani in India, where the Sterling Hospital, with Trained Western Style Doctors did a formal study of Prahlad Jnani not having eaten a thing for 65 years. They locked him up for 10 or 11 days and quantified everything and reported their observed findings. Upon Western Peer Review IT WAS ALL DISMISSED PRIMA FACIE -- IF IT CAN'T BE TRUE, WHY EVEN LOOK AT IT.
Atheists had always blamed the Religious for being bound to ossified Doctrines. Well, they need to look in the mirror on this one. They need to see how much they simply dismiss out of hand as conflicting with their Accepted Doctrines -- mostly that Nothing Religious Can Ever Be True.
