There is an account, of sorts, at the Penn student newspaper (it's sub-headline comletely mischaracterizes through innuendo what Wax said about slavery, judging from the account later in the body of the article–but this makes me wonder how reliable the whole thing is).   I can not tell to what extent Professor Wax addressed, if at all, the substantive (and devastating) criticism she receives from several of her colleagues.

UPDATE:  A friend at Penn points out that Professor Wax's entire talk can be viewed here.  I have not watched it, but may later.
