October 22,1954.- Y Professor Ludwig Von Mises, NEW YORK Dear Professor Von Mises: I want to thank you for sending me your article criticizing the use of mathematical methods in Political Economy.I have read it with great gusto.I also have lent it to some 08 my mathematical minded friends in the university. It has provoked in most of them a very strong and unfevourable reaction as could be expected. Professor Morgenstern whom-I came across at the Faculty Lounge= asked about you with great interest. I hope-if you have the possibility of doing it- that you will honour "Civis" with the contribution of one of your articles. Our publication upholds the same principles that have always accompanied you during your distinguished career. Sincerely yours Ruley humatte Carlos Luzzetti
