This discussion section is a result of an academic event organized at the Legal Research Institute, UNAM, in September 19, 2017 to commemorate the important work in moral philosophy of Professor John Broome. The event had an unexpected turn due to the earthquake that striked Mexico City at 1:14 p.m. that day. The event had to be cancelled in the middle of the sessions because the University decided to evacuated everybody from its campus as a precautionary measure. But inspite of the chaotic situation, the participants decided to continue the discussion in their hotel and discussion continued via emails to present the proceedings in Problema. The following people participated in the event: Alex Worsnip (UNC, Chapel Hill), Fernando Rudy Hiller (IIF-UNAM), Daniel Fogal (NYU), and Carlos Nuñez (University of Viena), and of course John Broome. My most sincere thanks to all of them, to Iwao Hirose who helped me organize the event and of course to the support of the Legal Research Institute at UNAM.
