It is possible, however, to inherit a set of unexamined beliefs, the way you get passed your language, food preferences and taste in clothing: these are completely non-rational and are acquired before the development of rational thought. Of course, the religious have noted this, and do their best to take advantage of it, first, by insisting on instilling their ideas as early as possible, second, by strongly discouraging rational enquiry into these same ideas.
In realms outside of religion, we can see that belief must be earned, and admits of degrees and change. I can believe that my team is going to win the World Series, or the Super Bowl, but realistically, I know that this belief, in itself, does not really affect the real world, and the belief is also subject to revision based on the evidence of constant losses, or player injuries, or whatever.
Belief in scientific theories or facts is also earned, and is not a matter of creedal assent, as so many christians seem to think. Such theories are supported by mountains of facts and information. Even if a new theory is proposed, it must still account for all the existing facts, do so better than the old theory; and should be a better predictor in other areas than the old theory was. Relativity did not change the behaviour of objects moving at speeds of a small fraction of the speed of light. Quantum mechanics does not affect the behaviour of real cats or blocks of wood.
However, Christian beliefs are the opposite. One day, it was OK to be an Arian and believe that JC and his dad were two different beings, then next day, in most of Europe, this was a heresy. (Spain was Arian until the early 8th century.) One day, it was heretical to believe that witches had any power over christians (9th century Papal ruling) Of course, we all know that later, it was heretical not to believe that witches existed and could cast spells and fly through the air to meet Satan. [Which is it now, Christians? Do you believe in witches? We know you believe in ghosts!] Of course the bible supports both beliefs. It used to be a sin to charge interest, so I hope no real christians particpate in banking of any kind. It is a sin to do anything that isn't a religious duty on the Sabbath, various groups have held it a sin to celebrate Christmas, or to not celebrate Christmas; presumably the truth of each proposition changes as you move from one country to another, or through time.
-- To know that the Bible is the literature of a barbarous people, to know that it is uninspired, to be certain that the supernatural does not and cannot exist--all this is but the beginning of wisdom.--Robert G. Ingersoll / Greg Erwin, VP, Humanist Association of Canada
