I'd also like to note that
opinions and beliefs can't argue with
facts and evidence. For example:
- Person A: I believe that Santa Claus exists. (opinion/belief)
- Person B: I don't believe that Santa Claus exists. (opinion/belief)
Here we have a disagreement of opinion/belief. Person A and Person B both probably have very good reasons for believing as they believe, and they aren't likely to settle their argument any time soon...if ever. Maybe person A could eventually convince person B that Santa exists...but that would have to be done with evidence instead of opinions.
A decisive argument isn't made with beliefs or opinions - it's made with facts and evidence.
However, compare the following:
- Person A: I believe that Santa's workshop is located at the North Pole. (opinion/belief)
- Person B: The North Pole has been explored and there are no workshops there. Therefore, Santa's workshop is not located at the North Pole. (fact/evidence)
Here we see a disagreement between an opinion/belief and a fact. The fact wins this disagreement hands-down. This doesn't mean that Santa doesn't exist - it simply means that his workshop (if it does exist) is not located at the North Pole.
Maybe Person A, having discovered this fact, will change their belief.
- Person A: I believe that Santa moved his workshop to Pluto to avoid discovery. (belief/opinion)
As more and more of Person A's beliefs are dis-proven, they become replaced with progressively implausible beliefs designed to be harder to disprove with evidence. Person A becomes less focused on being proven correct and more focused on not being proven wrong. However, this also makes Person A's position both implausible and more difficult for him to prove true.
This is the danger of supporting beliefs with beliefs - you build a house of cards that becomes less and less stable as we learn more about the world. Or, to relate this analogy to the Bible, think of the wise and foolish builder.
The man who supports his beliefs on evidence and facts digs down deep and lays his foundation on the rock, while the man who supports his beliefs with beliefs builds on the ground with no foundation. When the flood came, the wise builder's house was unshaken, but the foolish builder's house collapses.
The rock hard foundation are the facts and evidence the support a structured system of beliefs, and the flood is a flood of new information. Unfounded beliefs (beliefs with little or no support) will eventually collapse upon themselves as new information becomes available.
