The latest book of Piero Coda, Dalla Trinità. L’avvento di Dio tra storia e profezia (From the Trinity. The advent of God between history and prophecy), is the first volume of the series “Per-corsi di Sophia” (Per- courses of Sophia), which seeks to present, in accord with the academic project of the Sophia University Institute, the interdisciplinary research and lessons programmatically achieved in dialogue between professors and students. In its second edition after only a few months, this book is already finding a prominent place in the cultural debate, showing its validity, as intended by the Author, in creating and connecting occasions of dialogue, even within the various fields of study. A sampling is offered here in the reviews of an urbanist, a theologian and three philosophers: Elena Granata, Roberto Repole, Massimo Donà, Adriano Fabris and Vincenzo Vitiello.
