Despite the great risk of degeneration inherent in human relationships, it must be a great satisfaction to take part in an environment of cultural exchange, such as those that have taken place and those that exist in different countries, where a small group of intellectuals with a genuine common interest talk, teach, learn, help each other and develop. What seems most beneficial, and it does not always happen, is contact between different generations, which enables the personal transmission of a legacy, which should be equally satisfying for those who pass it on and those who receive it. In fact, this is what universities could do if they did not get involved in so many formalities. The value of physical presence—absent in books—cannot be underestimated, and so culture owes a lot to these small informal associations.
