Could It Be the Case That If I Am Right My Opponents Will Be Pleased ? A

I take up the four issues considered by Johnson-Laird, Byrne and Girotto in their reply to Politzer (2007). Based on the conceptual clarification which they adduce, it seems that the disagreement can be settled about the first one (truth functionality) and can be attenuated about the second one (the paradoxes of material implication). However, I maintain and refine my criticisms on the last two (negation and the probability of conditionals), backed up by considerations borrowed from the perspective of the conditional probability semantics for conditionals. keywords : conditional – probability of conditionals – negation of conditionals Guy Politzer CNRS – Institut Jean Nicod Ecole normale supérieure 29 rue d'Ulm, 75005 Paris, France email: [email protected] ijn _0 03 43 12 5, v er si on 1 29 N ov 2 00 8 Author manuscript, published in "Topoi 28, 1 (2009) 81-85" DOI : 10.1007/sl1245-008-9048-x
