After a brief introduction by Paolo Migone and Ulrich Wienand, the first chapter (pp. 5-13) of Aurel Kolnai’s book Psychoanalyse und Soziologie. Zur Psychologie von Masse und Gesellschaft ("Psychoanalysis and Sociology") is translated into Italian. This book, that was published in 1920 by the Internationaler Psychoanalytischer Verlag of Vienna as volume no. 9 of the Internationale Psychoanalytische Bibliothek, was written by Kolnai when he was 20 years old at the request of Sándor Ferenczi (both Ferenczi and Kolnai were of Budapest). It shows how the topic of the relationship between psychoanalysis and sociology had been discussed, and competently, already one century ago.
