John Gray argues that, throughout history, highly educated people have often made the worst decisions. Taking George Orwell as his starting point "There are some ideas so absurd that only intellectuals could believe them", he asks why we're still so reluctant today to give credence to the views of ordinary people. He examines the role of universities in teaching critical thought in the humanities and social sciences and wonders if students who have "swallowed this mishmash" really have a better understanding of the world around them.
