I was delighted to hear that this fall Michael Sandel has returned to teaching his Justice course at Harvard. He’d gone many years without teaching it, which I think was a shame, because that course does a better job than just about anything else I can think of at introducing people to philosophy. So it’s great to hear that it’s back.

I was twice a TA – or “TF”, for Teaching Fellow, as Harvard calls them – for Justice, now twenty years ago during my PhD. When Sandel interviewed me for the position, it was my favourite job interview I’ve ever had: the only interview where I was grilled on the finer points of Kant and Rawls. It was a proud moment for me because Sandel was skeptical about whether, as a religionist, I’d have the competence to teach the course, but I showed him how much moral and political philosophy I knew.

In those days at least, Justice was the most popular course at Harvard. It was held in the beautiful Sanders Theatre, Harvard’s largest audience space, and was so popular that the students who wanted to take it wouldn’t even fit in that space. That occasionally put us TFs in the position, not exactly standard for graduate students, of being bouncers: I told one student “I’m sorry, you’re not allowed in at the moment”, and she tried to go in anyway so I had to physically block her. Its popularity often made it a target for funny student pranks (see the picture).
