“Eureka" can be an answer to a question we have never asked. It can be the articulation of a sudden and unforeseen idea or the expression of a magic moment that throws us into a new world. It acts like a radiant sunbeam that comes out of the blue and illuminates a dim past, opening a new, dynamic horizon. It may even be a trivial but lucky encounter with new friends, who let us be what we are in our imagination: original and undifferentiated. (“Waiting for Eureka” )”
