IT is a sign of the speed at which events are moving that Hurst and Blackett's unexpurgated edition of Mein Kampf, published only a year ago, is edited from a pro-Hitler angle. The obvious intention of the translator's preface and notes is to tone down the book's ferocity and present Hitler in as kindly a light as possible. For at that date Hitler was still respectable. He had crushed the German labour movement, and for that the property-owning classes were willing to forgive him almost anything. Both Left and Right concurred in the very shallow notion that National Socialism was merely a version of Conservatism.
