Is it possible to validly invalidate logic without using logic?
Mere assertion gives rise to the question, "How do you know?".
At that point, you end up having to use logic to justify the thesis that... logic is invalid... lol
Or instead of trying to use logic to justify it, you can appeal to rank assertion or divine revelation. But these are both questionable bases (plural of basis) because two contradictory ideas would both be true...
So then does the impossibility of this feat actually prove of the validity of logic?
