Some context: 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.
Horney, together with fellow psychoanalyst Alfred Adler, formed the Neo-Freudian discipline. While Horney acknowledged and agreed with Freud on many issues, she was also critical of him on several key beliefs. Like many who held opposing views with Freud, Horney felt that sex and aggression were not the primary constituents for determining personality. Horney, along with Adler, believed there were greater influences on personality through social occurrences during childhood, rather than just repressed sexual passions. The two focused more on how the conscious mind plays a role in human personality, not just subconscious repression. Freud's notion of "penis envy" was particularly subject to criticism, as well. She thought Freud had merely stumbled upon women's jealousy of men's generic power in the world. Horney accepted that penis envy might occur occasionally in neurotic women, but stated that "womb envy" occurs just as much in men: Horney felt that men were envious of a woman's ability to bear children. The degree to which men are driven to success may be merely a substitute for the fact that they cannot carry, nurture and bear children. Horney also thought that men were envious of women because they fulfill their position in society by simply "being", whereas men achieve their manhood according to their ability to provide and succeed. Horney was bewildered by psychiatrists' tendency to place so much emphasis on the male sexual organ. Horney also reworked the Freudian Oedipal complex of the sexual elements, claiming that the clinging to one parent and jealousy of the other was simply the result of anxiety, caused by a disturbance in the parent-child relationship. Despite these variances with the prevalent Freudian view, Horney strove to reformulate Freudian thought, presenting a holistic, humanistic view of the individual psyche which placed much emphasis on cultural and social differences worldwide.

Some context: The Three Stooges were an American vaudeville and comedy team active from 1922 until 1970, best known for their 190 short subject films by Columbia Pictures that have been regularly airing on television since 1958. Their hallmark was physical farce and slapstick. In films, the stooges were commonly known by their actual first names. There were a total of six stooges over the act's run (with only three active at any given time), but Moe Howard and Larry Fine were the mainstays throughout the ensemble's nearly fifty-year run and the pivotal "third Stooge" was played by (in order of appearance)
On October 30, 2007, Sony Pictures Home Entertainment released a two-disc DVD set entitled The Three Stooges Collection, Volume One: 1934-1936. The set contains shorts from the first three years the Stooges worked at Columbia Pictures, marking the first time ever that all 19 shorts were released in their original theatrical order to DVD. Additionally, every short was remastered in high definition, a first for the Stooge films. Previous DVD releases were based on themes (wartime, history, work, etc.), and sold poorly. Fans and critics alike praised Sony for finally giving the Stooges the proper DVD treatment. One critic states "the Three Stooges on DVD has been a real mix'n match hodgepodge of un-restored titles and illogical entries. This new...boxset...seems to be the first concerted effort to categorize their huge body of work chronologically with many shorts seeing the digital light for the first time." Videolibrarian.com critic added "finally, the studio knuckleheads got it right! The way that the Three Stooges have been presented on home video has been a real slap in the face and poke in the eye to fans. They've been anthologized, colorized, and public domain-ed, as their shorts have been released and re-released in varying degrees of quality. Highly recommended." Critic James Plath of DVDtown.com added, "Thank you, Sony, for finally giving these Columbia Pictures icons the kind of DVD retrospective that they deserve. Remastered in High Definition and presented in chronological order, these short films now give fans the chance to appreciate the development of one of the most successful comedy teams in history." The chronological series proved successful, and Sony wasted little time preparing the next set for release. Volume Two: 1937-1939 was released on May 27, 2008, followed by Volume Three: 1940-1942 three months later on August 26, 2008. Demand exceeded supply, proving to Sony that they had a hit on their hands. In response, Volume Four: 1943-1945 was released on October 7, 2008, a mere two months after its predecessor. The global economic crisis slowed down the release schedule after Volume Four, and Volume Five: 1946-1948 was belatedly released on March 17, 2009. Volume Five is the first in the series to feature Shemp Howard with the Stooges and the final volume to feature Curly Howard. Volume Six: 1949-1951 was released June 16, 2009, and Volume Seven: 1952-1954 was released on November 10, 2009. Volume Seven included 3-D glasses for the two shorts: Spooks! and Pardon My Backfire. As of 2013, the 3-D versions of the two shorts in this volume have been removed. Volume Eight: 1955-1959 was released on June 1, 2010. This was the final volume of the Stooges collection, bringing the series to a close. Instead of two discs, Volume Eight includes three discs. It is also the final volume to feature Shemp Howard and the first and only volume to feature Joe Besser. For the first time in history, all 190 Three Stooges short subjects became available to the public, uncut and unedited. A 20-disc DVD boxed set entitled The Three Stooges: The Ultimate Collection, including all 190 shorts from volumes 1-8 and additional bonus material, was released on June 5, 2012.
