Fed up with the state's censoring of Plato, Joan of Arc and Romeo and Juliet, humanities professors are leaving Texas public institutions in pursuit of academic freedom. Texas A&M philosophy professor Martin Peterson is leaving the university after administrators told him in January that he couldn't teach Plato's Symposium in his philosophy class; they said the ancient Greek philosopher's work violated the system's restrictions on gender and sexuality content. Peterson's colleague Linda Radzik, a philosophy professor and associate department head, is jumping ship with similar concerns about academic freedom. Lucy Schiller, a nonfiction writing professor at Texas Tech University, also has plans to leave her job. They are just a few of the faculty members giving up their jobs at Texas public institutions
