👉 A metatheesis is a form of argumentation in which an argument is made that, while true for some purposes, is not necessarily true for all. It's like saying "I can't prove that this statement is always true because it depends on certain assumptions," but you don't have to prove the whole thing. Metatheses are often used in arguments where there are multiple premises and a conclusion that cannot be proven without including additional premises, which could lead to contradictions or inconsistency.
