ABSTRACT
This is written in homage to Pierangelo Garegnani, who not only has been a most faithful disciple to the Master but has in his own right been a creative innovator and expositor for the Sraffian heritage. None has benefited more than I from the Garegnani corpus (in English), both as a general reader but also in more personal communications. As I shall relate, Professor Garegnani on a good chance 1962 visit to Cambridge, Massachusetts prevented me from perpetrating a misdemeanor in print. And it was he—with Luigi Pasinetti, Michio Morishima, and Bruno, Burmeister and Sheshinski—who corrected in the 1966 Quarterly Journal of Economics an absurd conjecture that I had thrown toward an MIT graduate student. Yes, Homer nodded twice.
