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".
Timeline of psychiatry
French physician Bénédict Augustin Morel published "Traite des Maladies Mentales" (2 vols.); the 2nd ed. (1860) coined the term "dementia praecox" (demence precoce) for patients suffering from "stupor" (melancholia).
In 1857 he published "Traité des Dégénérescences", promoting an understanding of mental illness based upon the theory of Degeneration, which became one of the most influential concepts in psychiatry for the rest of the century.
