1. Despite my role of Professor in Administrative Law, I’m a person fully interested in other branches, as architecture, city life, planning and building, ecological rights, wild animals’ life, nature. There’s a notion I’m tied to: the “vital minimum”, or – as the German doctrine called it – existenzminimum. It is a concept transplanted in the Italian urban planning law in 1968, when a glorious battle was won to finally trigger a juridical idea of a sustainable, liveable city; I’m referring to the fabled d.m. no. 1444 of 1968, which – for the first time in our country – made politicians, citizens, people, understand that there were boundaries to decay of houseliving. As Aristotele said, indeed, “living” essentially means “living well”1.
It basically stands for – I add – living as the well-known Constitution of the United States of America (USA) says: searching – if possible – happiness. We have to try to reach happiness2. But this happiness cannot ever be reached without considering “the other”, “the neighbour”. And that’s a thing I deeply feel: there’s a well-known serenade by Rodriguez3 , a man that faced from the inside the Cuban Revolution, that says he is happy, really and deeply happy (muy feliz), and – at the same time – he apologizes to everyone has suffered for his happiness. Well, I think this is the sense of the real solidarity: to be grateful for everything – and everyone – has let a man, an animal, a being, when he could to, live pleromatically (I’m using the unforgettable words of a Master, Luigi Lombardi Vallauri). That is, to live fully and plenty of spirit. Seizing the day, but also watching prudentially to the future. Here is the topic of the next generations: an issue that I will just touch on. I said that I’m a jurist, but I love to snoop and look around even in fields that do not typically belong to law. Therefore, there’s a famous opera – in my opinion, the most gorgeous of the XXth century – that describes the profound sense of solidarity: Parsifal.
