I think it's a common mistake to imagine that we can actually choose our beliefs. It's better to ask questions, study, debate and reflect. Our beliefs happen while we engage in that process.
Pardon me, Cofty. This response was lost in the avalanche of information. Hence, the delay. Thank you, for taking the time to respond. Besides, others have had so much to contribute. Sorry that, I have no specific arguments or counter-arguments for the OP or later. For that, it may simply be disregarded by you or any other.
Your response is fascinating. Hence the question(open to all, of course): Are beliefs merely a function of the intellect? For if they are, then those are understandably subject to changes. Else, they are impervious to external, transitory factors.
