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".
Aaron T. Beck
In 1962, he was already making notes about patterns of thoughts in depression, emphasizing what can be observed and tested by anyone and treated in the present. He strengthened the new alliance with the psychiatrist Stunkard, and extended his links to psychologist colleagues such as Seymour Feshbach and Irving Sigel, thus keeping abreast of developments in cognitive psychology, as he did also from the new Center for Cognitive Science at Harvard University. He was particularly engaged with George Kelly's personal construct theory and Jean Piaget's schemas. Beck's first articles on the cognitive theory of depression, in 1963 and 1964 in the "Archives of General Psychiatry", maintained the psychiatric context of ego psychology but then turned to concepts of realistic and scientific thinking in the terms of the new cognitive psychology, extended to become a therapeutic need.
