The Nature of Logic

Tuesday 26 January 2016, 10.00AM to 6.15pm

Speaker(s): Saul Kripke, Michael Devitt, Romina Padro, Ian Rumfitt, and Rosanna Keefe

We are delighted to host Saul Kripke, Michael Devitt, Romina Padro, Ian Rumfitt, and Rosanna Keefe, at the University of York for a conference on ‘The Nature of Logic’ on the 26th January 2016. The topic of the conference will be the epistemology of logic, including issues concerning the choosing between rival logics, the practical significance of adopting a new logic, the requirements of an acceptable system of logic, the nature of logical inference, and the normative role of valid arguments. Some of the papers will address Kripke’s so far unpublished work on the ‘adoption problem’ - an interpretation of Lewis Caroll’s ‘What the Tortoise Said to Achilles’. 

Conference programme:

10am: Registration and welcome
10.30am: Romina Padro (CUNY) ‘What the Tortoise said to Kripke’
11.45am: Saul Kripke (CUNY) ‘The Adoption Problem and the Quinean Conception of Logic’
