Originally written for a national magazine—published to coincide with the release of Dianetics: The Modern Science of Mental Health it started a wildfire movement virtually overnight upon that book’s publication. Here then are both the fundamentals of Dianetics as well as the only account of L. Ron Hubbard’s two-decade journey of discovery and how he applied a scientific methodology to unravel the mysteries and problems of the human mind.

This book contains the only account of:

• How the optimum computing machine, the mind, works
• How L. Ron Hubbard discovered Basic Personality
• How wrong answers enter into the mind and are held down, giving further wrong answers
• How there seem to be “Demons” of the mind
• How Dianetics techniques were developed

The Evolution of a Science is the story of the greatest adventure of all—the exploration that discovered the Reactive Mind and the technology to conquer it.
