Devoted to Skepticism
I for one was trying to put my hands on it for some time. It turned out that Professor Burnyeat originally gave the paper at the Ancient Philosophy Colloquia at Princeton sometime in the 80’s – in fact, he is said to work on it just before the talk -, but then he never finished it, while others developed similar theses in print. If you manage to get a copy, please be so kind and share it with me.
So far no luck. But I hope that eventually I'll get my hands on a copy.And thanks for that piece of information, Máté.Cheers
