I'm not sure I understood all of this, but it seems like you are analyzing the merits of "faith" and arrive at the conclusion that faith limits our ability to discover more. Correct me if I am mistaken.

@plebeian_lobster I'd say a belief limits our ability to discover more. Faith seems to be more about not having all but just enough evidence to take action. There's an implied drive to discover more. Not so with beliefs, often they are people's conclusions formed without needing first-hand experience and evidence. That's how it looks to me for what it's worth.

@DavidBerigny I'm not sure I see a difference between what you say is faith and what you say is belief; I think the two are synonymous because if you believe something, then that something moves you to a certain action. Otherwise, do you really believe it? Ex. If I believe that when I hit the light switch, light will come on, then when I need light, then I will hit the light switch. I can say that I believe that hitting the light switch will produce light but never act on it, even when I need light, then I cannot really say that my belief is in fact a belief--it would have to be something else (maybe disbelief)?
As for faith, I have faith that the light switch will turn on when I hit it. I do not have a knowledge that the light switch will turn on--there are many things that could make the light switch not turn on when I hit it (e.g. power goes out, faulty wiring, etc.). Once, I hit the light switch and it turns on, then my faith that the light switch will turn on next time is increased a little. Obviously, that is a trivial example, but I think it can apply to bigger things, such as a belief in God.
If you are saying that belief implies inaction while faith implies inaction, then I would agree that your definition of belief would limit your ability to learn and experience things. However, I'm not sure how common that definition of belief is. In my view, faith and belief are either the same thing or inextricably intertwined so that you cannot have a belief in something without also having faith in that something, and you cannot have faith in something without believing in that something.

@plebeian_lobster I've talked to people that say they believe in UFOs without ever coming into contact with any. I've never heard anyone tell me they have faith in UFOs. Perhaps people use the words faith and belief differently without being so aware about their own implicit distinctions. I've also never heard anyone say they believe or have faith in the sun. I suppose some might as I heard about people worshiping the sun. Maybe they believe the sun requires worshiping? Is that a faith or a belief?

@DavidBerigny, do you think all of us, including animals, fish, worms, birds, etc . . .all came from the same primordial soup? No one knows for sure whether we actually have a life with God after death, but I would rather bank on that and a faith in God (I'm a Christian) than to live life here without faith in something other than what we have now. Christian teaching makes me a better person than no faith at all.

Think of it this way . . .can something be created out of nothing? If not, then how did the planets and earth come to being? A great explosion? Where did the explosion come from? A condensed mass of matter that exploded? Where did the dense matter come from? At some point you have to make a distinction that there is some ever present force that created the heavens and planets, and we are here for a reason.

@Mindful I've never heard anyone deny that an effect has a cause. But do we have the capacity to fully understand the cause of all causes? The force behind all forces? I don't doubt that to be what many call God. A word seems to imply there needs to be an agreed upon definition. At least to be practical so we can use language. But is God definable? If not, what do you mean by God?
