Bivalence | Berka I 31f Bivalence/Logical Form/Peirce: the fact that the sentence X is either true or false is written as: (x - f)(w - x) = 0 - Execution/(s): a) x = w : (1 - 0)(1 - 1) = 0 - b) x = f: (0 - 0)(0 - 0) = 0. I 32 Therefore, (x - f)(w - y) = 0 means that either x is false or y is true. - That is the same as "if x is true, y is true" - ((s) This corresponds to equivalence: Always the same truth value because of 1) presumed bivalence - 2) exclusionary or) - ((s) Bivalence/(s) couples x and y together, without any contentual determination, simply because merely one other truth value remains, which is thus determined.) - (>equivalence). |
