IF AN ITEM IS VALID (V), THEN SHOW THAT IT IS VIA PROOF OF VALIDITY (S); BUT IF IT IS NOT VALID. THEN FALSIFY THE CONSEQUENT (F). Therefore, if an item is not valid, then do not show that it is, or if the item is valid, then do not falsify the consequent. 1. If Mitch is free and willing, then Carl would date her (F, W, D). But Carl will not date her. So if Carl will not date her, then either Mitch is willing but not free, or is free but not willing, or not froo and willing
