Here we go! It is with distinct pleasure sharing this paper with my everpresent SF audience. It is the first one for this year. The topic is extremely timely: the morality of war. This is a real philosophical paper for the journal Moral Philosophy/Filosofia Morale. I thank Professor Roberto Mordacci, dean of the faculty of philosophy of Università Vita-Salute San Raffaele, for his kind invitation. It was the opportunity to write officially about Kant’s morality, one of my greatest philosophical conceptions. I reframed it and tackled the most difficult question in morals: can war be just? And the answer is resolute: no… but! And I leave you all with this hoping to have feedback on the reading. The paper can be found here: academia and on the journal’s webpage.
