“Houghton Mifflin moved aggressively to market the book, improving accessibility and price with a more mass-market edition. The new edition included a blurb from Dorothy Thompson, an American journalist who had been expelled from Nazi Germany. “As a liberal and democrat I deprecate every idea in this book,” she wrote. “The reading of this book is a duty for all who would understand the fantastic era in which we live, and particularly it is the duty of all who cherish freedom, democracy and the liberal spirit. Let us know what it is that challenges our civilization.””
