The essay offers, two and a half years after the disappearance, elements of reflection on Leonardo Benevolo, intellectual with a multidimensional character, protagonist of a long season of activities in the fields of culture, teaching, politics, publishing and profession. The article focuses on several aspects of its research, with particular attention to the different scales of the territorial project and the attempt to limit, through the plan, the influence of land rent. His activity tries to interweave the two themes with the aim of improving the conditions of social life in the modern city, at the same time enhancing the historical elements that have survived. All this cannot be generalized in a univocal spatial model, but is based on theoretical convictions, techniques and methods depending on the need to measure action with social, economic, environmental and physical contexts in which, from time to time, architects and planner are required to act. He appears as a connecting figure between important experiences, interlocked by a vision of society and of the city that escapes to predetermined schematism, by seeking constant measurement with reality. In the background, the article reflects on the function of the intellectual in Italy of the second half of the Twentieth century, in relation to issues related to architecture and urbanism, politics and academia.
