4 humours in respective order: choleric, melancholic, phlegmatic, and sanguine.
Four Temperaments is a theory of psychology that stems from the ancient medical concept of humorism.
History and development
Temperament theory has its roots in one of the ancient four humors theory. It may have origins in ancient Egypt or Mesopotamia, but it was the Greek physician Hippocrates (460-370 BC) who developed it into a medical theory. He believed certain human moods, emotions and behaviors were caused by body fluids (called "humors"): blood, yellow bile, black bile, and phlegm. Next, Galen (AD 131-200) developed the first typology of temperament in his dissertation De temperamentis, and searched for physiological reasons for different behaviors in humans. He mapped them to a matrix of hot/cold and dry/wet taken from the Four Elements. There could also be "balance" between the qualities, yielding a total of nine temperaments. The word "temperament" itself comes from Latin "temperare", "to mix". In the ideal personality, the complementary characteristics or warm-cool and dry-moist were exquisitely balanced. In four less ideal types, one of the four qualities was dominant over all the others. In the remaining four types, one pair of qualities dominated the complementary pair; for example; warm and moist dominated cool and dry. These latter four were the temperamental categories Galen named "sanguine", "melancholic", "choleric" and "phlegmatic" after the bodily humors. Each was the result of an excess of one of the humors that produced, in turn, the imbalance in paired qualities.
In The Canon of Medicine, Avicenna (980-1037 AD) then extended the theory of temperaments to encompass "emotional aspects, mental capacity, moral attitudes, self-awareness, movements and dreams."
Nicholas Culpeper (1616–1654) disregarded the idea of fluids as defining human behavior, and Immanuel Kant (1724–1804), Rudolf Steiner (1861–1925), Alfred Adler (1879–1937), Erich Adickes (1866–1925), Eduard Spranger (1914), Ernst Kretschmer (1920), and Erich Fromm (1947) all theorized on the four temperaments (with different names) and greatly shaped our modern theories of temperament. Hans Eysenck (1916–1997) was one of the first psychologists to analyze personality differences using a psycho-statistical method (factor analysis), and his research led him to believe that temperament is biologically based. The factors he proposed in his book Dimensions of Personality were Neuroticism (N) which was the tendency to experience negative emotions, and the second was Extraversion (E) which was the tendency to enjoy positive events, especially social ones. By pairing the two dimensions, Eysenck noted how the results were similar to the four ancient temperaments.
Other researchers developed similar systems, many of which did not use the ancient temperament names, and several paired extroversion with a different factor, which would determine relationship/task-orientation. Examples are DiSC assessment, Social Styles, and a theory that adds a fifth temperament. One of the most popular today is the Keirsey Temperament Sorter, whose four temperaments were based largely on the Greek gods Apollo, Dionysus, Epimetheus and Prometheus, and were mapped to the 16 types of the Myers-Briggs Type Indicator (MBTI). They were renamed as Artisan (SP), Guardian (SJ), Idealist (NF), and Rational) (NT). Rather than using extroversion and introversion (E/I) and task/people focus, like other theories, KTS mapped the temperaments to "Sensing" and "Intuition" (S/N, renamed "concrete" and "abstract") with a new pair category, "cooperative" and "pragmatic" . When "Role-Informative" and "Role-Directive" (corresponding to orientation to people or to task), and finally E/I are factored in, you attain the 16 types. Finally, the Interaction Styles of Linda V. Berens combines Directing and Informing with E/I to form another group of "styles" which greatly resemble the ancient temperaments, and these are mapped together with the Keirsey Temperaments onto the 16 types.
The four temperament types
Each of the four types of humours corresponded to a different personality type.
The Sanguine temperament personality is fairly extroverted. People of a sanguine temperament tend to enjoy social gatherings, making new friends and tend to be boisterous. They are usually quite creative and often daydream. However, some alone time is crucial for those of this temperament. Sanguine can also mean very sensitive, compassionate and thoughtful. Sanguine personalities generally struggle with following tasks all the way through, are chronically late, and tend to be forgetful and sometimes a little sarcastic. Often, when pursuing a new hobby, interest is lost quickly when it ceases to be engaging or fun. They are very much people persons. They are talkative and not shy. People of sanguine temperament can often be emotional.
A person who is choleric is a do-er. They have a lot of ambition, energy, and passion, and try to instill it in others. They can dominate people of other temperaments, especially phlegmatic types. Many great charismatic military and political figures were choleric. They like to be leaders and in charge of everything. They can be very manipulative.
A person who is a thoughtful ponderer has a melancholic disposition. Often very considerate and get rather worried when they could not be on time for events, melancholics can be highly creative in activities such as poetry and art - and can become occupied with the tragedy and cruelty in the world. A melancholic is also often a perfectionist. They are often self-reliant and independent; one negative part of being a melancholic is sometimes they can get so involved in what they are doing they forget to think of others.
Phlegmatics tend to be self-content and kind. They can be very accepting and affectionate. They may be very receptive and shy and often prefer stability to uncertainty and change. They are very consistent, relaxed, calm, rational, curious, and observant, making them good administrators. They can also be very passive-aggressive.
Decline in popularity
When the concept of the temperaments was on the wane, many critics dropped the phlegmatic, or defined it purely negatively, such as the German philosopher Immanuel Kant, as the absence of temperament. In the Five Temperaments theory, the classical Phlegmatic temperament is in fact deemed to be a neutral temperament, whereas the "relationship-oriented introvert" position traditionally held by the Phlegmatic is declared to be a new "fifth temperament."
Christian writer Tim LaHaye has attempted to repopularize the ancient temperaments through his books. In Waldorf education and anthroposophy, the temperaments are used to help understand personality. They are seen as avenues into teaching, with many different types of blends, which can be utilized to help with both discipline and defining the methods used with individual children and class balance.
Psychologist and writer Florence Littauer also describes the four personality types in her book Personality Plus.
One of the most current assessments of the four temperaments, Personality Dimensions, was created in 2003 in Canada, utilizing the work of Linda Berens, David Keirsey, et al.
Author Rupert Thomson used the four temperaments in his dystopian novel Divided Kingdom as the basis for dividing the population of a futuristic society.
LaHaye believes there are twelve mixtures of the four temperaments, representing people who have the traits of two temperaments, called Mel-Chlor, Chlor-San, San-Phleg, Phleg-Mel, Mel-San, Chlor-Phleg; and the reverse of these: Chlor-Mel, San-Chlor, Phleg-San, Mel-Phleg, San-Mel, and Phleg-Chlor. The order of temperaments in these pairs was based on which temperament was the "dominant" one (this is usually expressed by percentages). A person can also be a blend of three temperaments. Other four-type models, such as Social Styles, also have similar blends , and in the five temperament theory, the blends are defined along the three areas of "Inclusion", "Control", and "Affection". The blends expand the number of types to sixteen (twelve blends of two types, plus the four pure types) or more (for blends of three).
