Here's how I am interpreting your OP,
@Jeremiahcp : "Is the claim, 'I have evidence of X', actual evidence of X if the claimant cannot share his or her evidence with anyone."
Is that a fair paraphrase of the OP?
I actually considered using the word
evidence, but decided
proof was a more fitting word. We could nitpick at the literal definitions, but I think the word
evidence carries a more formal weight than the word
proof in casual debate
. I recognize that when people say, "I have proof", this is not always in the most formal sense and it can mean perhaps a wider scope than
evidence. They are essentially saying, "I have something which convinces me of something" and that is not the part I question.
However, I feel when you make a claim with another person (especially in a debate) then the validity of that claim becomes something that no longer pertains just to the individual; instead it is something that is gauged by everyone involved. If you cannot share this proof in some way, either directly, empathetically or some other way, then I feel the validity of the claim is greatly reduced.
The context of where the claim is being made also has an impact. In a bar if someone says, "I met Ozzy Osbourne" I am not going to challenge it. However, in a place like these forums, where even though it is casual, it is still debate I think a claim has more stringent standards to live up to.
Just a side note since you were talking about love and perhaps to give an example:
I actually feel the claim: "I believe in God because I can feel his love." is a valid claim. Now personally I feel they are anthropomorphizing their emotions, but at least I connect with the idea of believing in something because of an emotional reaction. It is something I have done myself and it is something I can relate to. I consider emotions to be a valid base for beliefs.
Now if someone tells me "I believe in God because I had a transcendental enlightening experience ", I am more incline to tell them they are full of it and their supposed "transcendental enlightening experience" proves nothing. There is no way for them to share that experience and there is no way for me to relate to it.
In order for a claim to have validity when you are sharing it with someone else; there has to be a way for that person to share in the proof that convinced you.
