Recensione di Paola Zambelli. Alexandre Koyré in Incognito. (Biblioteca di Galilaeana, 5.) xxii + 288 pp., bibl., index. Florence: Olschki Editore, 2016.

Alexandre Koyré (1892–1964) is one of the most important historians of science of the twentieth century, and his bold views on the philosophical background of scientific thought have always aroused both interest and controversy. It is therefore not surprising that scholarly work devoted to his life and career is animated and, in recent years, very intense. Since the late 1960s, Paola Zambelli, a distinguished historian of astrology and Renaissance philosophy, has worked extensively on Koyré and translated a few fundamental texts into Italian. With her present book, she highlights several unknown events in Koyré’s life, and her effort to contextualize them within the intellectual development of the Russian historian has led her to some original, though not always convincing, conclusions.
