Itinerary is somewhat autobiographical, for it is the story of the evolution of my political ideas. An intellectual biography but also a sentimental and even passionate one: what I thought and think about my time is inseparable from what I felt and feel. Itinerary is the story and description of a journey through time, from one point to another, from my youth to my present moment. The line that traces this plan is neither straight nor circular but a spiral that turns back ceaselessly and ceaselessly distances itself from the point of departure. What we are living today brings me close to what I lived seventy years back and, simultaneously, irremediably and definitively distances me. Strange lesson: there is no turning back but there is no point of arrival. We are in transit. Itinerary is the final work of a great thinker and magnificent writer.
