a) One can surely find something useful for Gödel, because I have my own results: I relied on logic and reason. Thus, one can prove Gödel even without speaking within the Mathematical convention.
b) I see it differently, I have far more text than the trolling "if there are absolutely undecidable things, then there are things that can't be decided".
c) We need to define what is Truth. A thing is called True if it will never be found false.
By that definition of Truth the undecidable things are always true. Because Reality is not an illusion, the two true things can not contradict each other. Therefore, any set of axioms is consistent. If axiom will be shown non-true, it can not be called axiom any longer. Again, all mathematics must be consistent, because Reality is not an illusion, and mathematics has in its origin the adding of the physical stuff, thus numbers are the Physics. If you have 5 fingers stretched and add 2 fingers, then you have 7 fingers.
I have defined the two words "devil" as one seen in the solar system, and "alien" as one seen in other star-system. One can not argue over the choice of definitions. Work then within my definitions of the words. For the sake of conversation. One can not disprove a definition, the definitions are the starting points for conversation. If a conversation can not start, the definitions can not be disproven; because disproof comes inside the conversation.
