What is a lie? what is the truth? It is very difficult to find the truth, and the descriptions of the same thing are different for different persons. So the title and its content is a lie.
In this case they are talking about mathematical truth, which is a case of Coherence truth.
If you say that "it is difficult to find the truth", aside from the blatant subjectivity of your claim, then , if we believe your statement, then that itself must be a "truth". And yet you invalidate your own claim immediately by saying "different for different persons". Well, if that statement is true, then it invalidates itself as well.
You cannot disprove the existence of truth by using a system that relies on truth and falsehood.
For example, the movement of things exists, but Newton's understanding of this existence is different from Einstein's understanding of the same existence (or the movement of more things).
By the way, you claim that the movement of things exists, but that is simply something you saw from your perspective without confirming the reality of that. Buddha would beg to differ given that according to him in scriptures, things were never born and don't decay etc.
If we assume that anything was actually born, then I say that it operates by the law of cause and effect, and the theory of repetition. These two laws create all phenomena and all other laws aiui. they're very simple.
And there is a difference between complexity of structures, and a given persons difficulty in understanding it. I do get the impression that you know this, but my point is that even what we call complex could be of the same difficulty to comprehend for someone who can see the universe whole. "for a real master of philosophy there is no difference in the difficulty of questions."
if you still believe that I'm missing your point please tell me again, so we can confirm.
When my son says, "I wasn't there" when the glass broke, it's not just a matter of differing descriptions, it's a clear denial of a fact. There are facts, and when someone deliberately twists or denies them, that's not just a different perspective. That's a lie.
The fact that is difficult to find out the truth, does not mean that something was or wasn't a lie. Paradoxically this is an attribute of a "good" lie: it is difficult to find out that it wasn't the truth.
There is a physical component to this lie but it seems to me that the social part dominates.
