Science of Survival Lectures Extension Course

Underlying the development of the Tone Scale and Chart of Human Evaluation was a monumental breakthrough: The Theta-MEST Theory, containing the explanation of the interaction between Life—theta—with the physical universe of Matter, Energy, Space and Time—MEST. In these lectures, delivered to students immediately following publication of the book, L. Ron Hubbard gave the most expansive description of all that lies behind the Chart of Human Evaluation and its application in life itself. Moreover, here also is the explanation of how the ratio of theta and en(turbulated)-theta determines one’s position on the Tone Scale and the means to ascend to higher states.
