I am proud to be a member of the Heterodox Academy (see http://heterodoxacademy.org/). Heterodox Academy members are all professors who have endorsed the following statement: “I believe that university life requires that people with diverse viewpoints and perspectives encounter each other in an environment where they feel free to speak up and challenge each other. I am concerned that many academic fields and universities currently lack sufficient viewpoint diversity—particularly political diversity. I will support viewpoint diversity in my academic field, my university, my department, and my classroom.”
