Ultimately people aren't going to agree on what is valid or not. We are talking about ideas, not about real things. I don't think there is such a thing as a "real" quantity.

In math we define things in terms of axioms. That defines what is valid or not. We can have opinions about whether we like a given set of axioms or not but I don't think we have some automatic shared idea on what is valid or not in mathematics.

Few mathematicians would have ever thought that until the 20th century. "Axioms" used to mean a self-evident or easily demonstrate truth. Now, because of the blunders modern math, "axioms" mean "any set of assumptions we take as a given and cannot prove."
There's no such thing as "self-evidence"
There are definitely self-evident truths.
"Every thing is exactly the way that it is, and it isn't however it isn't."
Self-evidently true.
Why is it self-evident?
