More Analysis Of "The Peculiar Institution"

I reviewed Kenneth Stampp's seminal treatment of slavery, titled "The Peculiar Institution" here several months ago. I'm pleased to see Rene Tyree, who runs Wigs-Wags, one of the best ACW blogs out there, reading and considering this book. Please take a look at his new post about it, the comment that I entered is below. I'm keen to see his response and please chime in on this issue whether you've read the book or not.
"I was struck, when I read the book, how Stampp used the work “positive” to describe those incentives. I don’t think it was for lack of a better term, I think he used it in a tongue-in-cheek manner. He knew full well how disgraceful it was to treat another human being like this, but managed to keep such editorial comment out of his book, which is one of it’s strengths. In using the word “positive”, I think he’s venting a little bit to show how there’s nothing at all positive about slavery"
