I have sometimes seem people (most recently, it seems to have happened fairly often among Muslims) suggesting that us atheists would have a choice to believe in God if we made an attempt, or sought evidence, something like that.
I'm not really very sure what they mean.
How often do theists believe or assume that atheism is a choice, I wonder?
Is it at all usual for theists to believe that atheism is changeable?
What do theists usually believe to cause atheism?
Anyone willing to say or guess? Let's try to avoid too much passion here. "Just the facts" (and respectful guesses), please.
Ultimately, belief in anything (including that there is a God, or that there is not a God) is a choice. That is especially true for the existence of God, for which there is neither concrete and objective evidence in favor or against.
To be a theist is to be willing to believe in the absence of concrete and objective proof that there is a God. To be an atheist (as opposed to an agnostic) is to believe in the absence of concrete and objective proof that there is no God.
In my experience, theists generally fall into two categories: those who choose instinctively to believe in God because they need the surety and structure of a fundamentalist religious life; and those who believe in God because they are open to spiritual experiences, and who incorporate doubt and uncertainty into a conscious choice to believe that the numinous they yearn for is out there, yearning back.
And also in my experience, atheists fall into two categories: those who are simply not inclined to spirituality, have not been raised with a religion, or were raised with a simplistic and overly literalistic religion that does not hold up to any kind of complex questioning, and thus simply see faith as unnecessary and inexplicable unreasonableness; or those who are cynical and skeptical, absolute empiricists, unwilling to even entertain the idea that there might be anything unexplainable by our science (or at least some science foreseeable to current thinking), and believe religion is just the opiate of the masses, spirituality just superstition and ignorance, and God just a fantasy embraced by ignorant dupes.
I would suppose any reasonable theist believes some atheists might reconsider their atheism, and some never would; much like some theists might reconsider their theism, and some never would.
But also in my experience, theists who try to sway atheists with "proofs" of God's existence are fools, because there is no objective evidence for God's existence-- all evidence for belief in God is ultimately subjective. And likewise, atheists who attempt to sway theists with allusions to science are also fools, since belief in God has nothing to do with science or ignorance thereof, and may in fact be driven by personal spiritual experiences unlikely to be dismissed by the experiencer.
