You confirm that this is true. In which case..... positive declaration (eg. 'x' exists).
I would suggest that the above statement is an 'if, then' proposition.
Anybody making this statement cannot be considered as 'making a claim'. It cannot be considered as "I definitively claim that 'x' exists".
Rather, the proposition is dependent upon somebody else's statement.
I recognise that this is a fine judgement, as a positive statement is being declared. However, I believe that the clause "in which case" confirms that this is a proposition, rather than a definitive 'I claim that 'x' exists'.
Am I correct?
The background to this question is fraught with difficulty.
It revolves around the limits of human knowledge, dealing with globally accepted, observable facts, that have no known explanation.
As a result, experts, posting on certain forums that operate at a certain level, are reticent to become embroiled in the discussion of potential explanation.
As a result... it is better to avoid an investigative path that leads to such a discussion.
Engineers have no such reticence... "it's all cause and effect, so deal with it".
On a Personal Note
I do accept the error that I made, when referring to the 'you'.
I should have said:
If this is true. Then..... positive declaration (eg. 'x' exists).
This was an honest human error, primarily due to my actual reliance on the expert at hand.
This was unfair on him.... particularly considering the gravity of what was being discussed. (I will apologise to him).
Anyway... apart from my human error.... I still rest with my title (unless a better title can be proposed).
Here is the link to the physics discussion.
It was shut down because it was deemed that I was falsely claiming something.
