A note on interpreting old temperament material

It’s usually pretty negative.

Take it with a grain of salt. We don’t know which individuals informed the perspective of the various historical commentators on temperament. They might have had in mind people who would, in our context, be in need of intense psychiatric care.

What I’m looking for when I read this stuff is tendencies, trends, clues as to how temperament was interpreted.

They shouldn’t be taken as universally authoritative texts.

Especially since they often contradict one another at various points!

I mention this because a reader wrote inquiring about part of Kant’s work that I quoted at length. Kant was a pretty unusual guy himself, but what does he mean when he says:

In case of perversion of his feeling and lack of a cheerful reason he succumbs to the adventurous: inspirations, apparitions, temptations.

If the understanding is even weaker, he hits upon grotesqueries: portentous dreams, presentiments, and wondrous omens.

He is in danger of becoming a fantast or a crank.

I think what Kant is describing is one of the dangers for a melancholic who loses his way. I stand to be corrected by any scholars of Kant who might come across this, but my interpretation is that melancholics are prone to let their ideals become detached from reality.

A ‘fantast’ is a dreamer, someone off on an adventure who follows (as Kant puts it) inspirations, apparitions and temptations.

A crank is an eccentric…the kind of person who clings to dreams and premonitions and omens.

I think Kant is warning that we can go off in strange directions if our ideals deviate too far from reality. This is under the heading of “degenerate form of the character”, so it’s not something we should all worry about.

Ultimately this is just Kant’s view. It tells us something about Kant, and the things he observed. I approach it as something potentially useful, but not necessarily true.

Then again, I’m a bit of a fantast and eccentric myself.


Medieval Latin rhymes about temperament

On the preservation of health in Medieval rhyming Latin verse.

Note how they conflate personality with physical features. Subsequent sections of the verse go on to describe physical symptoms of illnesses attributed to excess of each humour.

Complexions cannot virtue breed or vice,

Yet may they unto both give inclination.

The Sanguin gamesome is, and nothing nice,*

Loves wine, and women, and all recreation.

Likes pleasant tales, and news, plays cards and dice,

Fit for all company, and every fashion :

Though bold, not apt to take offence, nor ireful,

But bountiful and kind, and looking cheerful :

Inclining to be fat and prone to laughter,

Loves mirth, and music, cares not what comes after.


Sharpe Chollcr is an humour most pernitious,

All violent, and fierce, and full of fire,

Of quick conceit, and there withal ambitious.

Their thoughts to greater fortune still aspire,

Proud, bountiful enough, yet oft malicious,

A right bold speaker, and as bold a liar,

On little cause to anger great inclined,

Much eating still, yet ever looking pin’d.

In younger years they use to grow apace.

In elder, hairy on their breast and face.


The Flegmatique are most of no great growth,

Inclining rather to be fat and square,

Given much unto their ease, to rest and sloth.

Content in knowledge to take little share,

To put themselves to any pain most loth.

So dead their spirits, so dull their senses are :

Still either sitting like to folk that dream,

Or else still spitting, to avoid the flegme,

One quality doth yet these harms repair,

That for most part the Flegmatique are fair


The Melancholy from the rest do vary,

Both sport, and ease, and company refusing,

Exceeding studious, ever solitary,

Inclining pensive still to be, and musing,

A secret hate to others apt to carry:

Most constant in his choice, tho long a choosing,

Extreme in love sometime, yet seldom lustful,

Suspitious in his nature, and mistrustful,

A wary wit, a hand much given to sparing,

A heavy look, a spirit little daring-

*Nice used to mean ‘ignorant/foolish’, then came to mean ‘finicky, very particular’. I suspect the latter meaning in this context. The Sanguine is gameson and not very particular or finicky.

A brief history of temperament

The four temperaments theory is the oldest and most consistently utilised theory of personality in the Western world.

Its origins lie at least as far back as the 5th Century BC when Hippocrates, the father of Greek medicine, described human health and composition in terms of four humours or bodily fluids: blood, bile, phlegm and black bile.

The four temperaments were further developed and codified by Galen, personal physician to Roman Emperors in the 2nd Century AD. Galenic medicine remained the authoritative medical paradigm in Europe until the 18th Century, and his texts were still studied as late as the 19th Century.

But even as Galen’s theories about the human body were slowly discarded, his observations of the human mind continued to fascinate philosophers, physiologists, and psychologists even to the present day.

What underlies temperament?

Various theorists have attempted to define the temperaments in terms of more basic physical elements.

Galen described them in terms of heat and cold on the one hand, and moistness and dryness on the other. The Choleric is hot and dry while the Melancholic is cold and dry. Sanguines are hot and moist, while Phlegmatics are cold and moist.

But with the advances of medicine people have sought to describe the temperaments in ever more up-to-date terms, corresponding to changes in medical or psychological paradigms.

The 18th Century philosopher Immanuel Kant described the temperaments in terms of either feeling or activity that was short-lasting or long-lasting.  A Choleric is characterised by long-lasting activity while a Melancholic has long-lasting feelings. Sanguines have short-lasting feelings and Phlegmatics have short-lasting activity.

A generation later the German “father of psychology” Wilhelm Wundt described the temperaments in terms of either strong or weak emotion and slow or rapid change. Cholerics have strong emotion and rapid change, while Melancholics have strong emotion and slow change. Sanguines have weak emotion and rapid change, and Phlegmatics have weak emotion and slow change.

Another 19th Century German, the physiologist Jakob Henle, suggested that the temperaments might arise from the inherent activity or tonus of the nervous system.

Henle described each temperament in terms of the speed and the duration of reactions within the nervous system. Cholerics have quick reactions of a long duration while Melancholics have slow reactions of a long duration. Sanguines have quick reactions of short duration, and Phlegmatics have slow reactions of short duration.

The famous Russian physiologist Ivan Pavlov also studied the nervous system and he too drew on the ancient four temperaments to frame his theories.

For Pavlov the Choleric has a strong but unbalanced nervous system while the Melancholic has a weak nervous system. Both the Sanguine and the Phlegmatic are strong and balanced but the former is fast while the latter is slow. Though his studies focused on dogs, Pavlov applied his observations to humans also:

The melancholic temperament is evidently an inhibitory type of nervous system. To the melancholic, every event of life becomes an inhibitory agent; he believes in nothing, hopes for nothing, in everything he sees only the dark side, and from everything he expects only grievances.

The choleric is the pugnacious type, passionate, easily and quickly irritated. But in the golden middle group stand the phlegmatic and sanguine temperaments, well equilibrated and therefore healthy, stable…

The phlegmatic is self-contained and quiet, – a persistent and steadfast toiler in life. The sanguine is energetic and very productive, but only when his work is interesting, i.e., if there is a constant stimulus. When he has not such a task he becomes bored and slothful.

The psychologists

While the physiologists were studying nervous systems and linking their findings to the four temperaments theory, the new field of psychoanalysis founded by the Austrian physician Sigmund Freud approached the same questions of personality and temperament from a more psychological, clinically-oriented perspective.

Freud’s collaborator and contemporary Alfred Adler developed a personality theory that mirrored the four temperaments system.

Adler described each type or temperament in terms of high or low energy and high or low social interest. Adler’s Choleric equivalent has high energy and low social interest while his Melancholic equivalent has low energy and low social interest. Sanguines have high energy and high social interest, while Phlegmatics have low energy with high social interest.

Other psychoanalysts broke away from the four temperament model as they delved deeper into their own theories and observations. Carl Jung, for example, described a more complex range of cognitive functions and mental predispositions that were later codified into the famous Myers Briggs Type Indicator (MBTI), the most popular personality theory in operation today.

Yet the four temperament model was not entirely forgotten. It was retained primarily in the work of the psychologist Hans Eysenck, who described the four temperaments in terms of extroversion and neuroticism. Extroversion refers to how outwardly oriented a person is, while neuroticism is defined as a tendency to worry, anxiety, frustration, moodiness, and jealousy.

In Eysenck’s model the Choleric has high extroversion and high neuroticism while the Melancholic has low extroversion and high neuroticism. The Sanguine has high extroversion and low neuroticism, while the Phlegmatic has low extroversion and low neuroticism.

Temperament today

Modern trends in psychology and medicine make researchers wary of trying to match their research to pre-existing ideas and concepts like the four temperaments.

Contemporary psychology does draw on the concept of temperament, but it avoids the original four in favour of a research-driven approach. Psychologist Jerome Kagan is one example of an influential researcher on temperament, demonstrating throughout his career that key biological/behavioural traits in infants persist throughout adult life.

Kagan’s work focused on high and low reactive children, and he acknowledges that there are many other ‘temperaments’ or aspects of temperament yet to be studied.


For a lay person like me, learning about these different theories and approaches to the four temperaments adds to the sense that there’s a central phenomenon behind the archetypal four, and help us clarify exactly what the differences between them are.

As Kant wrote:

In this way the ancient forms can be preserved, and only receive a meaning better suited to the spirit of this doctrine of temperaments.

I still believe that Henle’s two-factor model of excitability versus duration of impression is the most fundamental, yet it helps me to have the others available too.

How better to explain a melancholic than “low energy, low social interest”? That’s me in a nutshell.

Other theories may seem more or less apt, but at the very least they show how different people have perceived the temperaments. We can also see where they have gotten it wrong, describing temperaments in ways that don’t at all accord with our experience, or letting their own temperament blind them to the true nature of the others.
