Allan Bloom's 1987 book "The Closing of the American Mind" heralded a debate about "political correctness" in American higher education in the 1980s and 1990s. Professor of English literary and cultural studies at CMU Jeffrey J. Williams wrote that the "assault on ... political correctness that simmered through the Reagan years, gained bestsellerdom with Bloom's "Closing of the American Mind"." According to Z.F. Gamson, Bloom's book "attacked the faculty for 'political correctness'". Prof. of Social Work at CSU Tony Platt says the "campaign against 'political correctness'" was launched by Bloom's book in 1987.
