Science of Survival is a 1951 book by L. Ron Hubbard, extending his earlier writings on Dianetics. Its original subtitle was "simplified, faster dianetic techniques", although more recent editions have the subtitle "Prediction of human behavior". It is one of the canonical texts of Scientology.The title of Science of Survival alludes to Science and Sanity, a highly popular work by Alfred Korzybski, the founder of general semantics. Hubbard acknowledged Korzybski's contributions in the book.It has remained perpetually in print over the years, and is currently published by Bridge Publications, Inc.Science of Survival was the follow-up to Hubbard's best-selling Dianetics: The Modern Science of Mental Health. It expanded significantly on Dianetics, setting out what Hubbard called the "dynamics of behaviour" and provided descriptions of new techniques of Dianetics processing that Hubbard described as being faster and simpler than those that he had advanced previously. In the book, Hubbard introduced two concepts that were later to become key elements of Scientology: theta and the tone scale. He also endorsed the concept of past lives. Source: Wikipedia (en)
