Kudos to Jeff McMahan, professor of philosophy at Rutgers University and a visiting research collaborator at the Center for Human Values at Princeton University, for writing the dumbest essay I ever read, and double-kudos to the New York Times for publishing it. I actually fell off my chair laughing. McMahan's contention is that we should engineer the selective extinction of all carnivores on Earth on the basis that they cause suffering to other animals. I don't know where to start with this, so I'm not even going to try, except to say that if you were ever looking for proof of why one should hesitate before going into press on a subject one knows nothing about, this is it. Meanwhile, I am sitting down to write an opinion piece on Schopenhauer, confident that the Times will publish it.
[PS, I wanted to comment on the piece, but I noted that after 270-odd comments along the lines of "what the f*@k?" the Times has disabled the comment function]
