The philosophy department is based in Ockham House, with philosophy classes held there and around campus.
Simmonds Library is located in the ground floor of Ockham House. It houses nearly 5,000 books and is utilized by faculty and students as a meeting space, study area, seminar room, and lounge. The library collection was donated by Kent Simmonds, professor emeritus of philosophy, upon his retirement, and is a useful resource for the Luther College community. The student-run Philosophical Society meets weekly during the academic year in the Simmonds Library.
