This document provides an introduction to the author's book on authoritarianism. It discusses how the author came to study authoritarianism after failing an exam question on the topic and getting caught up in trying to solve the puzzles it presented. It also acknowledges those who have supported the author's work over 40 years, including his wife, colleagues, and John Dean who discovered the author's research and inspired him to write this book. The author hopes to provide perspective to Dean's analysis of authoritarian leaders and the religious right for a non-academic audience by making the book freely available online.
