Is negation a truth functional connective?
Next, we note that the negation connective (~) is
truth-functional
. In other words, if we know the truth value of a statement S, then we automatically know the truth value of the negation ~S; the truth value of ~S is simply the opposite of the truth value of S. This is plausible.

Are all connectives truth-functional?
Classical propositional logic is a truth-functional logic, in that every statement has exactly one truth value which is either true or false, and
every logical connective is truth functional
(with a correspondent truth table), thus every compound statement is a truth function.
Is because truth-functional?
4 Answers. It is because ‘
because’ is not truth-functional
. For example, the two statements ‘Grass is green’ and ‘Snow is white’ are both true, but ‘Grass is green because snow is white’ is an invalid argument, and hence, as a statement as to the validity of that argument, a false statement.
