Dear Colleagues, I agree with Dusko that it is much better to avoid any offensive remarks and I agree with every word Marta says in what she calls her "seems to be 14th" message. On the other hand, it really feels as everyone is trying to argue against Jean, gently or less gently… and then it is understandable if Jean's remarks become a bit (or more than a bit) angry. Removing "offensive", "against", and "angry", I think this discussion was actually very useful since it gave new information on the history of an important mathematical discovery (I essentially knew what Ross said because I heard that from Ross before, but I did not know about Jon's talk in 1967 mentioned by Bill). Let me also add that [G. Janelidze and W. Tholen, Facets of descent I, Applied Categorical Structures, Vol. 2, No 2, 1994, 245-281] refers (for the "monadicity=descent") to both Bénabou and Roubaud and to Beck. However: while the precise reference on the Bénabou-Roubaud paper is given there, Beck's name is mentioned without any reference to a paper (since as far as we knew he did not publish such a paper). I also had feeling confirmed by this discussion that nobody really remembers what exactly did Jon do, while the Bénabou-Roubaud paper is available to everyone… George Janelidze
