This article is a republication of a chapter in The Road to Serfdom, “The End of Truth.” Hayek addressed Western intellectuals and political leaders, dedicating the book “To socialists of all parties.” The book beseeches them to consider how they were not as different from their 1944 foreign enemies as they imagine. In this chapter, he explains the kit that a bad regime uses to keep and consolidate power, including propaganda, censorship, persecution, the perversion of language, and a whole-of-society approach to corrupt discourse, science, and public thought generally. The despotic kit is, Hayek says, “destructive of all morals;” it brings the end of truthfulness. The chapter is reproduced by permission of University of Chicago Press and Taylor & Francis/Routledge.
