Scientology has a common source — the psychiatrist-psychologist-psychoanalyst clique". In a letter addressed to the FBI dated July 11, Hubbard reports having been the victim of an "attack made by psychiatrists using evidently Communist connected personnel". In 1956, Hubbard wrote an article entitled "A Critique of Psychoanalysis" which embodies Hubbard's harder stance. Writes Hubbard: "Now and then it becomes necessary to eradicate from a new subject things which it has inherited from an old. And only because this has become necessary am I persuaded to tread upon the toes of the "grandfather" to Dianetics and Scientology." In the essay, Hubbard admits that from "the earliest beginnings of Dianetics it is possible to trace a considerable psychoanalytic influence." Hubbard makes a distinction between Dianetics and Scientology writing that "Scientology, unlike Dianetics, is not a psychotherapy. It is therefore from the dominance of Scientology rather than from the viewpoint of Dianetics that one can understand the failings of psychoanalysis, its dangers and the reasons why it did not produce what it should have produced." We discover psychoanalysis to have been superseded by tyrannous sadism, practiced by unprincipled men, themselves evidently in the last stages of dementia. This, then, is the end of the trail for psychoanalysis—a world of failure and brutality. Today men who call themselves analysts are merrily sawing out patients’ brains, shocking them with murderous drugs, striking them with high voltages, burying them underneath mounds of ice, placing them in restraints, “sterilizing” them sexually and generally conducting themselves much as their patients would were they given the chance. It is up to us to realize, then, that psychoanalysis in its pure practice is dead the moment the spirit of humanity in which Freud developed the work is betrayed by the handing over of a patient to the merciless misconduct which passes today for treatment. In 1957, Hubbard founded the "National Academy of American Psychology" which sought to issue a "loyalty oath" to psychologists and psychiatrists. Those who opposed the oath were to be labelled "Subversive" psychiatrists, while those who merely refused to sign the oath would be labelled "Potentially Subversive". In 1958, Hubbard wrote that "Destroy is the same as help to a psychiatrist". His 1958 writings cited "Psychiatry: The Greatest Flub of the Russian Civilization" by Tom Esterbrook; Hubbard's son would later reveal that Tom Eastebrook was one of Hubbard's many pen-names. In 1966 Hubbard declared all-out war on
