“What I still do not believe is that we should add Asian philosophers, or African-American philosophers, to the curriculum in order to “encourage” (on some misguided theory) minorities to enroll in philosophy courses.”
I agree. We certainly should not add anyone to the curriculum on the basis of a misguided theory. But knowing all that we know about stereotype and implicit bias, we have very well-supported theories in favour of adding demographic diversity to our syllabi. Knowledge of these theories tells us that our selections for syllabi are very likely influenced by implicit biases which it make it more likely that we will select white men. It also tells us that demographically diversifying our syllabi is no mere marketing ploy, but rather something which is likely to have real effects on the attitudes not just of students from underrepresented groups, but also on those of other students.* Those who are making such suggestions are not acting as “identity politics police”, as Leiter would have it. We are carefully examining the evidence, and working to improve our profession. Eugene Park’s testimony is a further piece of evidence (albeit anecdotal) that these suggestions are on the right track.
