“There’s no such thing as mathematical truth, math is just another language-game’.”

Refutation: Negating statements about value and meaning that intend to cover all statements are (often) performative fallacies.

This is a fallacy that, by necessarily referencing itself or its own state, causes a violation of orders and logic. I.e: “My existence is an illusion.”

If I say “All language is just a game without meaning”, or “Consciousness is an Illusion”, such statements undermine their own value/validity as a first move. If ‘everything is an illusion’, or my mind is an illusion, the idea that it makes valid or useful statements is also an illusion…

It is a performative fallacy due to the following problem that arises as a necessary consequence of the statement ‘There is no such thing as mathematical truth’. This would invalidate »analysis and measurement. Without analysis and measurement, statements about ‘truth’ are, themselves, meaningless. Therefore it is useless to make them.
