Thanks, I hadn't read the intro paragraph in italics, as I saw the first paragraph was what had been quoted. You are right. And Hudson was right then and is now. My bad.

I am also glad I successfully resisted characterizing Samuelson by inserting what would have been the third word of the title, although my fingers are gnawed as a result. It would have been uncivil and disrespectful.
