Via Eric Johnson-DeBaufre, librarian at the Robbins Library of Philosophy at Harvard University, come a pair of audio recordings of J.L. Austin discussing performatives.
The first is a lecture, and the second contains a question and answer session. The lecture took place in October, 1959, in Sweden. It’s currently unknown who recorded them.
Great find. Somebody surely will recognise his persistent questioner in the second tape. He maintains his position well. It would be good to know who was in the room, about 10 people from internal evidence
