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".
Parataxical Integration
The concept first appeared in Sullivan's "The Interpersonal Theory of Psychiatry", published in 1953. It was developed further by his protégé, Lorna Smith Benjamin, in her "Interpersonal Diagnosis and Treatment of Personality Disorders" (1996). Benjamin saw parataxical integration as typical in the interpersonal behavior of couples with unresolved autonomy (i.e. separation, boundary) and identity issues. Erik Erikson had himself described the unconscious, reciprocal reactivation (without using Sullivan’s terms) in his essay, “The Problem of Ego Identity,” and in "Identity and Anxiety", by Stein "et al". (1960).
