Dianetics 55! (December 1954): Research after the publication of The Creation of Human Ability began to undercut the lofty goals of COHA to provide a sure route by which more people could realize the promise of that book's breakthroughs. The foundation of that route was and remains communication, which is the focus of Dianetics 55! Ron gives the complete anatomy of communicaton as well as the formulas for good communication. The fundamental principle behind the workability of auditing or any therapy is good communication, hence the importance given to it in Dianetics and Scientology. To emphasize this book's importance he named it the Second Book of Dianetics.
