"I began studying Aristotle when I was still a student here in Padua. When I decided to write my thesis, I approached a professor who seemed particularly interesting to me, Marino Gentile. I told him about my interests, which centred on the debate on metaphysics, in particular the objections that contemporary philosophy raised against metaphysics, represented by major currents such as Marxism, existentialism and positivism, which were hostile to metaphysics. The professor advised me to read Aristotle's Metaphysics, a text I had already read for some university exams. Reading it, I realised that there were still many things to be clarified, even though Aristotle was considered by my colleagues to be an outdated philosopher. Perhaps this was also due to the cultural isolation that Italy suffered as a result of the war and the presence of the historicism of Giovanni Gentile and Benedetto Croce. In other European countries, he was still a relevant philosopher, especially in English philosophy, within the context of reflection on everyday language; English scholars continually discussed Aristotle. In Germany, Heidegger, one of the greatest philosophers of the last century, devoted a great deal of attention to Aristotle. Over time, I continued to study Aristotle, discovering more and more how relevant he was. Today, Aristotle is one of the most studied philosophers in the world and is considered an interlocutor, in contrast to those currents that are now almost obsolete."
