OT 1948: Introduction

Reference: DIANETICS: The Original Thesis

This paper presents Chapter 1 from the book DIANETICS: THE ORIGINAL THESIS by L. RON HUBBARD. The contents are from the original publication of this book by The Hubbard Dianetic Foundation, Inc. (1948).

The paragraphs of the original material (in black) are accompanied by brief comments (in color) based on the present understanding.  Feedback on these comments is appreciated.

The heading below is linked to the original materials.



In nineteen thirty-two an investigation was undertaken to determine the dynamic principle of existence in a workable form which might lead to the resolution of some of the problems of mankind. A long research in ancient and modern philosophy culminated, in nineteen thirty-eight, in the heuristically discovered primary law. A work was written at that time which embraced man and his activities. In the following years further research was undertaken in order to prove or disprove the axioms so established.

Certain experiences during the war made it necessary for the writer to resolve the work into applicable equations and an intensive program was begun in nineteen forty-five toward this end.

A year later many techniques had been discovered or evolved and a nebulous form of the present work was formulated. Financed chiefly by a lump sum disability compensation, that form of Dianetics was intensively applied to volunteer subjects, and the work gradually developed to its present form.

Dianetics has been under test by the writer, as here delineated, for the past three years. The last series of random volunteers, numbering twenty, were rehabilitated, twenty out of twenty, with an average number of work hours of 151.2 per subject. Dianetics offers the first anatomy of the human mind and techniques for handling the hitherto unknown reactive mind, which causes irrational and psychosomatic behavior. It has successfully removed any compulsions, repressions, neuroses and psychoses to which it has been applied.

KEY WORDS: Human Condition, Dianetics, Investigate

When investigating a pervasive condition, one starts as broadly as possible, and establishes certain axioms. These axioms are then resolved into applicable equations and workable techniques. One then tests these techniques and refines them.

In this case that pervasive condition being investigated is the irrational behavior and psychosomatic condition originating from the mind.

    In the introduction it seems LRH had a keen interest in the workings of the mind and was determined to look at its function and malfunction, i.e. The reactive mind. It was indeed a unique and ambitious undertaking. Raju Rao
