The Concept of Anxiety
The Concept of Anxiety (): "A Simple Psychologically Orienting Deliberation on the Dogmatic Issue of Hereditary Sin", is a philosophical work written by Danish philosopher Søren Kierkegaard in 1844. The original 1944 English translation by Walter Lowrie (now out of print), had the title The Concept of Dread. "The Concept of Anxiety" was dedicated "to the late professor Poul Martin Møller". He used the pseudonym Vigilius Haufniensis (which, according to Kierkegaard scholar Josiah Thompson, is the Latin transcription for "the Watchman" of Copenhagen) for "The Concept of Anxiety".

He wrote in January 1949 that he was working on a "book of psychology" about "the cause and cure of nervous tension", which he was going to call "The Dark Sword", "Excalibur" or "Science of the Mind". On March 8, 1949, Hubbard wrote to friend and fellow science-fiction author Robert Heinlein from Savannah, Georgia. Hubbard referenced Heinlein's earlier work Coventry, in
in which a utopian government has the ability to psychologically "cure" criminals of violent personality traits. Wrote Hubbard: 
His first published articles in Dianetics were "Terra Incognita: The Mind" in the Explorer Club Journal and another one that impacted people more heavily in Astounding Science Fiction.
