AutoRicerca is a journal whose mission is to publish writings of value on the topic of inner research (but not only). This eighteenth volume is the first to be published only in English. It contains an interesting conversation between D. Aerts, K. W. Ekeson, M. Sassoli de Bianchi and V. Schneider, on "The secret of life." It also contains two original articles, written by D. Aerts and K. W. Ekeson, which complete the content of the conversation.
