This is a graduate-level research seminar in the philosophy of logic. We will look at recent controversies, as well as classic work and theories which inform those newer debates. Topics will include what logic is and how to understand logical consequence, logical constants, the epistemology of logic and the question of how to choose the correct logic, the question of whether there can be more than one correct logic, as well as questions about whether logic is a priori, analytic, necessary, or normative. The course will offer opportunities to develop skills in both writing and presenting philosophy.

We are fortunate to have two guest speakers who will be visiting our seminar (in person) this semester: JC Beall, from the logic group at the University of Connecticut, Storrs, will visit us to talk about First Degree Entailment and the one true logic on March 1st, and Mario Gómez-Torrente, from UNAM (the National Autonomous University of Mexico) will be asking what makes something a logical constant on March 8th.

When we have guest speakers, members of the seminar are invited to accompany the speaker for dinner afterward and you are strongly encouraged to attend.

Assessment will be by way of a research paper on a topic of your choice, due on the last day of classes. (4000 concise and carefully chosen words would be reasonable, but your paper may be shorter or longer if the topic demands it.)

Each student will also be required to give one 15-minute in-class presentation during the semester. I will ask you to email me your top three choices for date/topic after the first class. I will then put together a schedule for the presentations.

Presentations should not try to summarise ALL the reading for that class. You should pick one or two points that you found interesting or which raise questions, and present these clearly in order to kick off discussion.

I recommend coming to see me during the week before your presentation, in order to talk over your plans.

It would also be a good idea to come and see me at least once during the semester to talk about your paper project.

The research paper is worth 80% of your grade. The presentation is worth 20%
