“Planning and Prioritized Defaults”

by Dustin Tucker (Ph.D., University of Michigan), Visiting Assistant Professor of Philosophy, Texas Tech University

Location: Lory Student Center, Room 214-216

Free and open to the public.

ABSTRACT: As theories of reasoning, traditional logical systems are highly idealized and impractical. John Horty has argued that more realistic, everyday reasons are best thought of in terms of defeasible rules of inference called defaults, and Richmond Thomason has proposed using a logic of such defaults to think about the way we reason and plan with desires and beliefs. Unfortunately, combining Thomason’s suggestion with Horty’s more robust framework raises puzzles. After briefly reviewing Horty’s system, I show how it can be reworked to capture hypothetical reasoning, which resolves the puzzles. I then turn to potential limitations of this approach raised by what might be called wishful planning—planning for desired outcomes that we think are unlikely.
