Welcome to our meeting, in a city which is very Italian and very Swiss at the same time. In fact, it has the extraordinary characteristic of being what one would call an ambiguity or, as others would call it, an extraordinary synthesis. This city is our host, and in a certain sense it is a symbol of the Balzan Foundation, which is an Italian-Swiss foundation. I don’t think we could hold our conference in a better place, especially because we are in this city’s university. Only three decades ago it did not exist, and now it has assumed the role of being one of the most interesting among the Italian language universities. Because of its young age its fields of activity are maybe still somewhat limited, but they attain a very high level.
