(This seems to be the most recent post directly relating to the OP, though I will comment that I think it’s silly to argue about ‘what atheists believe’ when the term is used by one person to mean a certainty-level belief that no God exists, by another person to mean a personal absence of belief in any god, by a third to indicate the disbelief of the specific few gods that they’ve heard about, and by a fourth person to refer to any person (including self-procaimed agnostics) who hasn’t specifically identified themselves as a theist. Heck, “religious person” is a more uniformly defined and understood term.)
Scylla, what you describe here seems to only glancingly align with what I thought the definition of the word ‘faith’ was in this thread. The closest you get is “Faith. Faith let’s you act when your intelligence would otherwise dictate that you shouldn’t bother. It gives you the will to act on something doubtful as if it were true.”, and then you proceed to defend the small subset of ‘faith events’ where the belief being held is merely that one might succeed when the odds are against him; where the actions the person believes in following are a rationally determined (though perhaps improbable) course of action (as opposed to, say, sitting in the airplane praying or singing the latest Weird Al song), and where the success being sought is a specifically noble and worthwhile endeavor. You most certainly are not defending the person who has faith that spending his family’s food money on lottery tickets is so certain to succeed that he need not get a real job, or the person who has faith that merely praying is a better way of dealing with a broken arm than going to a doctor, or a person who believes that killing innocent bystanders will ensure themselves a special place in heaven.
Not to be rude, but the specific case of faith that you find valuable is such an uncommon example of faith that it isn’t hardly a defense of faith at all. It’s like defending ‘dismembering people’ based on the specific case where the individual in question is on the verge of slaughtering a whole crowd of innocent people, and the only possible way of stopping him happens to involve the unavoidable consequence of tearing him apart. It just doesn’t carry any weight in relation to the entire concept under discussion.
(Also, I call the virtue you’re touting “will” or perhaps “determination”. The dude with faith sits in plane and prays (and dies).)
It seems that in this thread a lot of the defense of the value of faith is based in focusing on a limited subset of faith applications (for example those that produce good outcomes) and are deliberately ignoring all the bad things that have been known to happen when people base their beliefs on that absence of evidence known as “faith”, and then act on those unsupported beliefs. (For example, racism is pretty much entirely a faith-based construct, though neither exclusively a religious or nonreligious one.)
As a practical matter, if you ignore all the bad outcomes of something and pay attention to only the good outcomes, then you can defend the claim that anything has value. (For example, the sodomizing of small children is in good to do because it causes pleasure for the sodomizer. --not a belief I hold, by the way.)
Needless to say, no defense of faith or anything else that relies on ignoring large portions of its effects and applications will ever be very convincing to me. That people bother to present such arguments makes me wonder if they have ever honestly considered the effects of the thing in question, outside the rosy image of it they have constructed for their personal edification.
