The Logic and Reasoning Institute and the Department of Philosophy and Religion are co-sponsoring the following colloquium talk:

"Modal Validity and Logical Validity" Trenton Merricks (Department of Philosophy, University of Virginia)

ABSTRACT: Let an argument be modally valid just in case, necessarily, if its premises are true, then its conclusion is true. Logical validity, unlike modal validity, is defined in terms of an argument’s form. So the concept of logical validity is not identical with the concept of modal validity. This paper will defend a number of claims, some surprising, about the relation between logical validity and modal validity.

3:30 Friday February 5 in Cleveland Hall 114
