I've been thinking about if logic is meaningful and if so, what makes logic meaningful. Or more precisely, what makes the assertion that logic is meaningless meaningless. Do you require logic to question the validity of logic or attempt to establish its invalidity (because otherwise words, prepositions etc. would be useless)? Or is that the result of the a priori adaptation of the meaningfulness of logic? If it requires logic to question the validity of logic, then that is an internal contradiction?
