"Agreed. And now, we can agree that there are truths which do not require observable empirical testing. They are true in their inherent rationality.
I give more credit to our rational faculty than you do, Phooney. You only accept what you can prove has been demonstrated by whatever physical observable science is available at any given time. I say our rational faculty can lead us into higher truths."
This is very interesting. I will take some time at some stage to read up on tautologies in propositional logic.
I have already mentioned such things that are proven through retortion, like me saying “I exist”. The inherent truth of tautologies is something else that I am fine with. I think it is safe to say that yes tautologies are true by definition, but they don’t neccesarily have any correspondence reality or existence. Your unicorn tautology is a good example, just because a unicorn eats hay or it doesn’t, says nothing about whether unicorns exist. Also, while true, they are incoherent if you or nobody else knows what a unicorn is, with as much meaning to people as complete gibberish. Just as a logically sound argument is only true when the premises are true, despite being logically sound.
Are you saying “God exists” is a tautology or something?
“There are mathematical truths, for example, which cannot be tested empirically.”
Sure, such as we can say that the number 5,392,292,748,173,290,098,234,138,490,914,579,249,428,752,049,872,049,872,432,569,293,239,726,239,923^134,094,029 is a number, but nobody will ever count to it. Nobody can bring out some giant scales and weigh the earth. Luckily for us such mathematical truths are built on simpler proven concepts, that allow us to satisfactorily prove complicated concepts that we are, I agree, unable to test empirically.
"It is not uncommon for a physicist to say, “we know x is mathematically true, but we cannot prove it observably.”
Agreed. However, again, mathematically true and mathematically sound doesn’t automatically mean reality and existence. The example I have brought up earlier in this thread, and in the last one, was loop vortex theory, which was mathematically sound and matched observations, but has been proven to not be an accurate model of the universe.
The tautologies you’ve presented here aren’t rational justifications for belief in anything. You seem to be hell bent on arguing against what you perceive to be my materialist position, which I don’t think I fall into anyway.
Coincidentally, I requested and received a book for Christmas called “What we Believe but Cannot Prove: Science in the Age of Certainty” which I am looking forward to reading, but it is a few books down in the list at the moment.
“If you could BOLD or something my stuff or your stuff when you respond, I could get through it more quickly…”
Apologies for this. I was mauled as a small child by a website’s quote function and have avoided them ever since, I will try to use it from now on. I see by quote 669 that you have some problems with it as well!
Ditto to A’s opinion of your posts!!
Thanks to you as well. Rereading some of my posts I think some of my wording has seemed a bit on the harsh side towards you. Please put this down to, in one case, me being quite tired, and in
another case being in a bit of a rush. I have not intended to be spiteful to anybody here who was conversing intelligently.
You can see where I was going with the tautology by my shorter response and non-observable truths.
Yes indeed.
