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".
Cognitive therapy
Beck outlined his approach in "Depression: Causes and Treatment" in 1967. He later expanded his focus to include anxiety disorders, in "Cognitive Therapy and the Emotional Disorders" in 1976, and other disorders and problems. He also introduced a focus on the underlying "schema"—the fundamental underlying ways in which people process information—about the self, the world or the future.
