In April I took part in a panel discussion on solitude, along with authors Eleanor Catton and Yiyun Li and host Bridget Kendall, on BBC World Service’s program The Forum. (Update: I thought the podcast was going to expire on July 28, but it appears that it will be up for another year.)
Also, you may be interested Melvyn Bragg’s recent discussion on the philosophy of solitude, also on BBC. (Because my streaming is spotty, I haven’t listened to it yet, but I hope to do so soon. It looks promising.)
Finally, you may enjoy the recently posted samples from my students’ philosophy journal, CONTRARIWISE.
