There is no burden of proof if one isn't trying to convince another.
I don't really think we have much of a choice in that matter. You and me talking here, I at least, don't get the impression that either of us are especially concerned or interested in trying to convince the other of anything, as much as we are just sharing our views on this particular topic. But by doing so, you might give a reason or explanation that convince me that you are right, even though that weren't your motivation at all.
I think the moment we discuss something with each other and share our views, we automatically also try to convince the other, unless we are in complete agreement already.
If so, that's an alien way of thinking to me. I simply wouldn't use the words "I believe" (explicitly or implicitly) unless I considered the belief correct, even if it's not. I'm still looking for a rule from you that will allow me to know which expressed beliefs you don't consider claims. I can't discern one.
But simply believing something, doesn't imply certainty. Believing something is merely a position about a given thing or topic, its not something which we can directly question, so if we have two overall beliefs.
My believe: "I think there is other lifeforms in the Universe"
Your believe: "I don't think there is other lifeforms in the Universe"
If I simply said to you "Your believe is wrong" it wouldn't have any meaning, because on its own I can't tell you what you believe is right or wrong, only you know that.
But we could have a discussion about what made you believe that and why I believe what I do. And these are points where we could "attack" each other. And even here we could have believes as well, because you could believe a certain person, which had the view that life simply couldn't exist in the Universe and he made a case for this somehow or whatever. But this is based on this persons claims about knowing something about lifeforms in the Universe.
So if we should try to illustrate it.
<1. Your belief> <---
<2. Experiences/Exposure/Claims/Beliefs>
1. We could refer to this as you overall believe about something.
2. Would be the foundation for which you have based your overall believe on or whatever have convinced you that it is true.
Does that make sense?
If not, here is a very basic example:
I believe chocolate tastes better than strawberry, the reason I believe this is because I have tasted both of these. The foundation for my believe is that I tasted both.
For example, it seems to me that you would call your statement that the proof of God is in the life and words of Baha'u'llah a claim, but not that Baha'i is a correct religion, but maybe you consider them both claims or neither. I'd like a clear understanding of how you decide as I have given you. You know that if I make either of those statements, I consider them claims of fact: for me, the evidence supports belief and makes the religion correct. I still can't do that with you.
Its like above, Baha'u'llah made a claim that he was a messenger of God or whatever. The burden of proof is on him.
A person comes along and say they believe he was telling the truth. So now they are a Bahai follower.
Now you come along and question Baha'u'llahs claim, the burden of proof doesn't suddenly shift to the person that believe Baha'u'llah were a messenger, just because you don't believe it. That claim is on him and will always be.
But you can have a discussion with the Bahai follower, in regards to how they reached the conclusion that Baha'u'llah were telling the truth and what convinced them. This will lead to them having to create an argument for their position which contains a lot of claims and they are responsible and have the burden of proof for these.
(Sorry noticed I accidentally quoted the wrong reply, but given it follows the say discussion I just left it here
)
Yes, for me, the words "I believe" are implied whenever a claim of fact is made. Nothing is a fact because somebody says it is, and even when we agree, we are essentially saying we believe as well.
Well if we follow normal definitions, we would say that it is a fact that we will die, it is a fact that gravity exist etc. And I agree something is not a fact simply because we say so, it is a fact because it have proven to be so. Obviously we can't be certain, that we in some magical way won't die, or that gravity stops to exist tomorrow. But that is beyond rational thinking in regards to how we perceive reality and use the word fact.
