Karen Horney was born Karen Danielsen on 16 September 1885 in Blankenese, Germany, near Hamburg. Her father, Berndt Wackels Danielsen (1836-1910), was Norwegian but had German citizenship. He was a ship's captain in the merchant marine, and a Protestant traditionalist (his children nicknamed him "the Bible-thrower", as he did indeed throw Bibles). Her mother, Clotilde, nee van Ronzelen (1853-1911), known as "Sonni", was also Protestant, of Dutch origin.
Theory of the self
Horney also shared Abraham Maslow's view that self-actualization is something that all people strive for. By "self" she understood the core of one's own being and potential. Horney believed that if we have an accurate conception of our own self, then we are free to realize our potential and achieve what we wish, within reasonable boundaries. Thus, she believed that self-actualization is the healthy person's aim through life--as opposed to the neurotic's clinging to a set of key needs.  According to Horney we can have two views of our self: the "real self" and the "ideal self". The real self is who and what we actually are. The ideal self is the type of person we feel that we should be. The real self has the potential for growth, happiness, will power, realization of gifts, etc., but it also has deficiencies. The ideal self is used as a model to assist the real self in developing its potential and achieving self-actualization. (Engler 125) But it is important to know the differences between our ideal and real self.  The neurotic person's self is split between an idealized self and a real self. As a result, neurotic individuals feel that they somehow do not live up to the ideal self. They feel that there is a flaw somewhere in comparison to what they "should" be. The goals set out by the neurotic are not realistic, or indeed possible. The real self then degenerates into a "despised self", and the neurotic person assumes that this is the "true" self. Thus, the neurotic is like a clock's pendulum, oscillating between a fallacious "perfection" and a manifestation of self-hate. Horney referred to this phenomenon as the "tyranny of the shoulds" and the neurotic's hopeless "search for glory". She concluded that these ingrained traits of the psyche forever prevent an individual's potential from being actualized unless the cycle of neurosis is somehow broken, through treatment or, in less severe cases, life lessons.
