The University of Hawaii at Hilo has told a philosophy lecturer who swore in the classroom that his services won’t be needed next semester, according to an article in The Honolulu Star-Advertiser. The lecturer, Daniel Petersen, said he had told students that “stuff happens”—though he used a more emphatic word than “stuff”—to illustrate concepts like free will and determinism. Parents complained, and Mr. Petersen was suspended without pay. Then he was informed that he wouldn’t be returning to teach next semester. Mr. Petersen told the newspaper that he planned to sue the university.
