The author also makes a significant contribution by locating Posadas’s eccentricity in the broader context of the s and s, when both the possibility of nuclear apocalypse and interest in ufology and the space race were actually widespread. Gittlitz rightly points out that the peak of Posadas’s political influence “overlapped with the more ardent period of the space race” (p. ). Both in the introduction and in the conclusion of his book, Gittlitz –whose first name, as with J. Posadas, remains a completely mystery to the reader – seems to suggest that there is something more than irony in the recent reappraisal of Posadism through memes and jokes, namely the appeal of apocalyptical perspectives in a time of crisis and climate catastrophe. Even if one is not willing to go that far, it is worth celebrating the idea that prompted the author towrite a useful book that sheds light on the history of revolutionary ideas andmovements in the twentieth century.
