"These tapes provide the only existing running day-to-day, week-to-week record of the progress of research in Dianetics and Scientology. They were blazing a trail from total ignorance of the subject to today. Man knew nothing about the mind when it began and we are where we are today. And these tapes were the milestones on the road out."
—L. Ron Hubbard
