Origins of a "Science"

So where did L. Ron Hubbard come up with the idea for Dianetics? Well, Scientologist believe that Hubbard was source, meaning that he came up with everything by himself. They refer to his creation of Dianetics as the "bolt from  blue", however the truth is far more interesting. Dianetic auditing is actually merely an altered form of of Psychiatric therapy called Aberactive Therapy. Also Engrams as defined by Hubbard are remarkably similar to Freuds theory of repressed memories. Simply put, most of Dianetics is simply Freudian theory with a mix of post-WWII-era computer science terminology such as keyed in, and bank.
