the point isn’t to prove that the triangle is a triangle it’s to prove that the system of mathematics you made up actually works

Nobody is practically concerned with the “incompleteness” aspect of Gödel’s theorems. The unprovable statements are so pathological/contrived that it doesn’t appear to suggest any practical statement might be unprovable. Consistency is obviously more important. Sufficiently weak systems may also not be limited by the incompleteness theorems, i.e. they can be proved both complete and consistent.
Oh, what if the Riemann hypothesis is such a statement then? Or any other mathematical statement. We may not have any use for them now, but as with all things math, they are sometimes useful somewhere unexpected.
I think the statement “this system is consistent” is a practical statement that is unprovable in a sufficiently powerful consistent system.
Can you help me understand the tone of your text? To me it sounds kinda hostile as if what you said is some kind of gotcha.
It’s very counter intuitive. As the other commenter suggested I was referring to Gödel and his incompleteness theorem.
Actually if the system you made up doesn’t work it would be possible to prove that it does inside that system as you can prove anything inside a system that doesn’t work.
That is why my comment is not entirely accurate it should actually be: Until you prove that if the system works you can’t prove that the system works.
Can you spot the difference in the logic here?
You can tell it’s a triangle because of the way it is.
that won’t work for yoda, though. for him, there is no triangle. there’s just doangle or donotangle.
I nearly failed geometry because I didn’t understand what my instructor wanted from me.
Even philosophy 101 can give you a ton of reasons why looking at it just isn’t enough
