"Curiosity has this fantastic characteristic that it makes the questions more interesting than the answers. Questions open doors to other worlds, other realities, inexhaustible sources of enrichment. If we had all the answers, life would be reality, without dreams, without theories, without research, without ... questions! The only interest in the answer is the development covered, and that it often brings other questions, leading us elsewhere, and finally, constructing ourself. After all do we really want to know everything? Don't we prefer to maintain a part of the unknown that allows us to believe in something else?"
