5.44 Truth-functions are not material functions.

If e.g. an affirmation can be produced by repeated denial, is the denial—in any sense—contained in the affirmation?

Does “~~p” deny ~p, or does it affirm p; or both?

The proposition “~~p” does not treat of denial as an object, but the possibility of denial is already prejudged in affirmation.

And if there was an object called “~”, then “~~p” would have to say something other than “p”. For the one proposition would then treat of ~, the other would not.
