Doesn't concern me in even the tiniest, most infinitesimal amount. Remind me to post on the rationalist virtue of zs'hanh at some point.

According to the provided link, zs'hanh means "contemptuous indifference to the activity of others". I'm not sure how that's supposed to apply here, since the entire subject of discussion is the activity of others (namely, Gary Drescher's writings).

If what you mean is that I should have tried to evaluate his ideas on the object level instead of depending on the opinion of others, I did say that I was unable to make sense of his subjunctive relation. Given that, it doesn't seem wrong to check if anyone else could make sense of it and be concerned that no one apparently could.

Drescher on subjunctives - I agree, this strikes me more as Drescher trying to make partial progress toward a solution than presenting something well-defined in a logical sense. I'm not sure Drescher would disagree with that.

He has told me that he now regards the decision theory approach in "Good and Real" (as well as the newer "meta-circular" approach) as inadequate and has recently been "rebooting" his thinking in order to try to find the right approach from a fresh perspective. (He seems to think that UDT is more promising but may not be the right approach either.)
