I just wrote the following in a forum for reasons originally completely unrelated to any argument favoring religion.  I’m sure this argument has been made by many who favor religion (though I don’t know that I’ve actually read it anywhere, it has to have been written before), but I like to put it in my own words.

The pure irrationality of religion would be an example of a right-brained or intuitive thing that the left has to accept.  There is no way to logically prove that the dictates of any religion are truthful or valuable, but the fact is that there is an observable cause and effect, manifesting its own reason, in following those dictates.  People do good things based on the irrational dictates of their religion, which cause them to feel good, and live more abundant lives, and, since the dictates of religion can neither be logically proved or disproved, it is worth it to risk that the reasons of religion may be true, not false - because _if_ they are true, then there is something real and valid behind the observable happiness in following the ultimately purely irrational dictates of a religion.  And if they are false, why not follow religious dictates anyway?  What would it hurt humanity, if religion is false, to live lives deluded by the happy imaginations of heaven, if we’re all going to die and obliterate into an unknown nothingness anyway?  An unknown nothingness would be the ultimate hurt; delusions of a happy heaven would be no hurt at all compared to that hurt.  That the thought of an unknown nothingness fills man with fear is proof itself that the makeup of man longs for something beyond this life.  Given that none of it can be proved, and it could be either way, I’d pick a life of either delusions about heaven or experienced knowledge of heaven - I’d pick that over nothing at all, risking that heaven could be real.
