Laughing means placing yourself towards others events of reality without accepting them passively, but with at least a minimum of active detachment: now with surprise, now critically, now as a choice of lively sharing. We laughed in the long winters of Prehistory, we laughed in the dark ages of the Middle Ages, we laughed during the endless European conflicts and Asians and Americans of the Modern Era, even the Jews continued to laugh, for a long time everywhere discriminated against, despised and persecuted. So what right would we have today to refuse to do so?
