Computers are the best thing on planet earth at calculating , we use them to do exactly that!
I don't think you know what you mean anymore.
We know what is true by what is evident. Truth by definition is belief based on evidence.
But it is easy to prove you wrong about what you think truth is, you see it as infinite truth.....something we dont have! Never have had! We have made many mistakes as a race as have many living things. Believing assumptions such as the earth being flat, but when more,evidence came to light, adapted our 'truth'.
Truth is dependant on what we learn via our inputs, our eyes, our nose, our ears...all our senses. We saw a flat earth with our eyes and for most of humanity that was the truth about our pkanet, of course it wasn't true.
You assume our truths are true and therefore there must be a source. But we will likely be proven wrong about much that we know. So how can you guve 'truth' such status?
What is tue, is simply what we observe. One and one apples amounts to having two apples.
That is logic and language, we assigned the word apple to the item in the tree and we measure quantity with words we have ascribed a number system to.
Somehow you think this means there is a soul. Without explaining it, you say "i am not sure you understand."
Of course I don't! I don't think you do either. We have now gone from math, to truth... I wonder what is next?
You can't ascribe truth to maths, it is our mechanism of measurement. We literally wrote the rules for maths and continue to do so. We have math based on a decimal system, as I said, it could have been based on a system of 6 heximal? and we would have computers earlier in human history (maybe). Math is not a perfect, unbreakable truth!
I could say the length of my forearm is the measurement 'zingabumbum' and then quantify a numerical system based on my forearm measurement and the bum bum numerical system. It would be useable, it would be true, it would be applicable to science, learning, logic...everything... but it would be my invention. Hardly infinite truth.
