The Faces of Janus
The Faces of Janus is a book by A. James Gregor, in which the author argues that there are fundamental errors in Marxist analyses of fascism and that the political spectrum identifying the Left as progressive and the Right as reactionary was a dishonest way of "privileging purported movements of the Left and demonizing movements of the Right".
However, Adler also criticises Gregor, saying of the book:
Reviewer Harry V. Willems of the Southeast Kansas Library System writes:
The American Historical Review wrote that Gregor argues that fascism "was a compelling and coherent synthesis of ideas generated by some of the most creative thinkers of our time."
