The president of Ball State University is forbidding faculty to endorse intelligent design, the belief that the universe is too complex to have evolved by chance.
President Jo Ann Gora has sent a letter to faculty and staff saying intelligent design is not appropriate material for science courses.
Gora said only humanities or social science courses may discuss topics like intelligent design, as long as professors do not openly support it.
That letter comes after an atheist group complained that the school hired a science professor who wrote a book on intelligent design and another professor was accused of teaching creationism.
Ball State is a state-supported university in Muncie, Ind.
