Please join us for tomorrow's Linguistics & Philosophy Joint Seminar Monday Jan 17th, 4pm G15 Chandler House Seth Yalcin (Berkeley) *'On Some Counterexamples to Modus Ponens and Modus Tollens' * * * *This talk is about whether the principles of Modus Ponens and Modus Tollens are valid for natural language indicative conditionals. I will describe one well-known alleged counterexample to Modus Ponens (MP), due to Vann McGee, and one counterexample of my own to Modus Tollens (MT). I will argue that while McGee's counterexample founders, mine succeeds. I'll then supply a semantics for the conditional, and a characterization of consequence, that validates MP while invalidating MT. I'll argue this semantics and definition of consequence have substantial independent motivation. But I'll close with discussion of some recalcitrant data -- data which may suggest that the MP and MT are both based on a syntactic mistake. My larger aim in this talk will be to become clearer on the sense in which MP and MT are, in the setting of natural language semantics, empirical hypotheses.* *__._,_.___* Reply to sender<[email protected]?subject=Re%3A%20Seth%20Yalcin%20talk%2C%20UCL%20Linguistics%20%26%20Philosophy%20joint%20seminar%2C%2017th%20January>| Reply to group<[email protected]?subject=Re%3A%20Seth%20Yalcin%20talk%2C%20UCL%20Linguistics%20%26%20Philosophy%20joint%20seminar%2C%2017th%20January>| Reply via web post<http://groups.yahoo.com/group/esap-news/post;_ylc=X3oDMTJwdTd2N21hBF9TAzk3MzU5NzE0BGdycElkAzIxNzkwMDMwBGdycHNwSWQDMTcwNTAyMDU4NQRtc2dJZAM3NjAEc2VjA2Z0cgRzbGsDcnBseQRzdGltZQMxMjk1MTgyOTg4?act=reply&messageNum=760>| Start a New Topic<http://groups.yahoo.com/group/esap-news/post;_ylc=X3oDMTJmZ2xhMnBiBF9TAzk3MzU5NzE0BGdycElkAzIxNzkwMDMwBGdycHNwSWQDMTcwNTAyMDU4NQRzZWMDZnRyBHNsawNudHBjBHN0aW1lAzEyOTUxODI5ODg-> Messages in this topic<http://groups.yahoo.com/group/esap-news/message/760;_ylc=X3oDMTMzcmlpcG1mBF9TAzk3MzU5NzE0BGdycElkAzIxNzkwMDMwBGdycHNwSWQDMTcwNTAyMDU4NQRtc2dJZAM3NjAEc2VjA2Z0cgRzbGsDdnRwYwRzdGltZQMxMjk1MTgyOTg4BHRwY0lkAzc2MA-->( 1) Recent Activity: - New Members<http://groups.yahoo.com/group/esap-news/members;_ylc=X3oDMTJncTV0OG44BF9TAzk3MzU5NzE0BGdycElkAzIxNzkwMDMwBGdycHNwSWQDMTcwNTAyMDU4NQRzZWMDdnRsBHNsawN2bWJycwRzdGltZQMxMjk1MTgyOTg4?o=6> 5 Visit Your Group<http://groups.yahoo.com/group/esap-news;_ylc=X3oDMTJmNmNlcDhhBF9TAzk3MzU5NzE0BGdycElkAzIxNzkwMDMwBGdycHNwSWQDMTcwNTAyMDU4NQRzZWMDdnRsBHNsawN2Z2hwBHN0aW1lAzEyOTUxODI5ODg-> [image: Yahoo!
