In 1979 Alberoni published his best-seller "Falling in Love". In the book, which further develops and expands the ideas and theoretical models from "Movements and Institutions", he maintains that the experience of falling in love is in essence the nascent state (or "ignition state") of a collective movement made up exclusively of two people. This time, however, Alberoni explores the subject in greater detail, using as much as possible the language of love stories rather than the abstract jargon of psychoanalysis or sociology. This book, which was rigorously scientific and at the same time innovative in its linguistic slant, turned into an international best-seller translated into twenty languages. After more than ten editions, it is still in print in Italy.
