Robert Paul Wolff replies re: the prisonder's dilemma.

A couple of days ago I posted a criticism of Robert Paul Wolff's dismissal of the prisoner's dilemma . Wolff has now posted a reply on his blog (quoting the version of my post I had emailed to him). He is pressing the fact that game theory is only properly-speaking a study of decision under certainty, while the problem I identify (which is hardly original on my part!) is to do with decision theory, etc, regarding  decisions under uncertainty. He thinks I'm not really addressing decision theory head-on, and in turn I think he's not really addressing the concern head-on (as I have said in my response there). That's how philosophy works: round and round she goes, where she stops, nobody knows. But every iteration hopefully we know more than at the beginning: I certainly find exchanges like my current one with Prof. Wolff to be very helpful.
