The lectures below were recorded as they were delivered — to students on course, to auditors in professional training, and to the congresses that gathered each year to hear the latest findings. Taken in order they are a running record of how the subject developed, year by year, from the first Dianetics course lectures of 1950 to the New HAS Course of 1975.
Each year below opens onto the series recorded in it, with a description of what that series covers. Choose a year to begin.
