“To illustrate the importance of knowledge sharing, I would like to tell you a little lesson in economics: I have a block of butter, and you have three Euros. If we proceed to do a transaction, you will, in the end, have a block of butter, and I will have three Euros. We are dealing with a zero sum game: nothing happens from this exchange.

But in the exchange of knowledge, during teaching, the game is not one of zero sum as more parties profit from the exchange: if you know a theorem and teach it to me, at the end of the exchange, we both know it. In this knowledge exchange there is no equilibrium at all, but a terrific growth which economics does not know. Teachings are the bearers of an unbelievable treasure – knowledge – which multiplies and is the treasure of all humanity.”
