History as profession is a socially useful job. It should be. When you read Fontana, fully understand what this means. And his lessons confirm this. The pleasure of following them, and now reading them, always leads to a reflection process that removes the reader of the topics and further the risk of thinking, to rethink things. When this happens, the historian knows he has done his job. And, reading Fontana, this happens.n n(From the "Presentation" by Josep-Maria Terricabras)n
