500 B.C.: The Pythagorean Theory of Opposites

One of the themes in our asthma and respiratory therapy history is that asthma and asthma-like conditions were rarely considered important enough to be studied. For this reason the tree of asthma wisdom was ever so small for most of history, growing ever so slowly through the passing years.  Why this occurred may be best explained by the Pythagorean Theory of Opposites.

Consider that for most of history there were far more apparent and deadly diseases than asthma, such as influenza and tuberculosis.  Plus asthma was thought to be a rare disease that killed very few of its victims.  So if you had asthma, chances are you suffered privately, leaving little or no impression on society of the disease that plagued you.

The Pythagorean Theory of Opposites was made famous around 500 B.C. by a famous philosopher by the name of Pythagoras (535-475 B.C.  The theory states that in order to understand something you have to have experienced its opposite. Since few experienced asthma, then few would understand it, and few would have empathy for the plight of the asthmatic.

However, while Pythagoras is often given credit for the theory, it may have actually been created by the pre-Socratic philosopher Heraclitus of Ephesus (535-475).  

Heraclitus believed the world was not static but dynamic.  He was a follower of the Pythagorean School, and he was one of the first philosophers of ancient Greece, one of the first people who stated that there was more to the world than that it was just created by the gods.

He believed in the unity of the world, and he believed the essential element of change was fire.  Where fire is involved, great changes occur.  Fire in the body causes sickness just like fire in a home destroys the home. He thus believed fire created air, water and earth.

He believed everything came along due to tension and strife, which can be produced by fire.  A good example is war, which is one of the major causes of change.  He believed that all things are moved by an innate force, and from opposite tensions results harmony.

It was by this theory, some believe, that he developed the theory of opposites. He believed everything had an opposite, and when these two opposites were in harmony you had peace. He believed that all things are moved by an innate force, and from opposite tensions results harmony.

Thus, it is in opposites, he believed, that we become aware of things.  By seeing the sick we appreciate health.  By seeing the dead we appreciate life.  By sleeping we appreciate being awake.  By seeing evil we appreciate goodness.  By seeing antagonists we appreciate protagonists. By seeing hunger we appreciate satiation. By seeing asthma we appreciate breathe.  

When changes occur to one or the other opposite, then this is where your conflict occurs. For example, when both hot and cold are balanced in the body, the body remains healthy. Yet when the heat of your body is increased, you become sick. The same can be said of dry and moist, sweet and bitter, and rest and weary.

It was this same theory that was adapted by the Hippocratic writers when they wrote the Hippocratic Corpus.  They used this theory of opposites to describe how disease was created, and how such imbalances can cause the four humours to become imbalanced, thus resulting in sickness.  So the Pythagorean Theory of Opposites may have been the birth of humoral medicine.

The premise of this theory is that in order to understand the plight of mankind, you have to have walked in their shoes.  In order to understand their suffering, you have to have had exposure to their suffering.

It doesn't have to be a major exposure either. For example, you don't have to get asthma to appreciate the person with asthma; all you have to do is meet an asthmatic, or read about his plight.

500 B.C.: Pythagoras introduces Greece to philosophy

Pythagoras of Samos (570-495 B.C.)
Even though he made no direct impact on medicine itself, Pythagoras of Samos (570-495 B.C.) may well be the most significant figure to our asthma history. The reason is because he might have been responsible for bringing Egyptian and Babylonian philosophy, math, astrology and medicine to ancient Greece.

By no means am I implying here that Pythagoras invented philosophy, for that couldn't be further from the truth: the quest for knowledge, which is what philosophy is, started long before Pythagoras was even born.

Near the beginning of civilization there were a few sages who pondered in secret about the world around them, and doubted it was all created by the gods.  They asked questions and sought answers, and what they discovered became the first theories.

They studied the stars and planets and became the first astrologers.  They studied numbers and became the first mathematicians.  They studied geometry and became the first architects.  They studied medicine and became the first physicians.

Pythagoras celebrates sunrise (by Fyodor Bronnikov)
Such wisdom was only privy to a select few members of the priesthood or aristocracy, and what they learned was used to advance civilization.  An anonymous sage in Sumeria invented the potter's wheel to make clay pots, and and another sage learned how to build channels and aqueducts to irrigate the land. Another anonymous sage invented a language and a system of writing.  An anonymous sage in Egypt invented the material and tools for building massive pyramidal structures, and another learned how to mummify the dead to prepare their bodies for the afterlife.

The problem with this early philosophy was that it was far and few between.  The majority of the people, about ninety-nine percent of them, worked a minimum of twelve shifts everyday, seven days a week.  They did not have time to think and ask questions let alone time to learn.  Yet during the 9th century B.C. things were occurring in ancient Greece that would change all this, thus giving rise to the Age of Philosophy in ancient Greece.

No one knows exactly when this occurred, but sometime before the great poet Homer sat down to write his epic poems, gymnasiums were being built near the temples of various gods,and these were dedicated to shaping the bodies of young men.  (1, page 80)

In these gymnasiums young men would exercise, play games, and otherwise prepare their bodies for battle. Occasionally they ventured off to battle, and they won many wars, and they marched home with prisoners of war.  These prisoners were turned into slaves, and by the 6th century B.C. nearly all the citizens of Greece owned many slaves, and these slaves did all the work.  This allowed the citizens of Greece plenty of time to enjoy the pleasures of life.

Some citizens spent their days pondering about the world around them, and they yearned for answers.  So they traveled abroad to Egypt, and Mesopotamia, and India.  In this way, they spent time with the sages of these places, and they expanded their knowledge.

At this time, the best medical schools were in Egypt, and therefore it was probably at the schools at Heliopolis that the Greeks came into contact with Egyptian medicine. They must have been very impressed with this knowledge that they took it home and shared it with their fellow citizens of Greece. (7, page 22)(6, page 4)

It was in this way that the Egyptian method of healing at temples morphed into Aeslepion temples in Greece.  Apollo was a god similar to Thoth.  Thoth was worshiped as Hermes.  Other Egyptian gods, such as Isis, were worshiped in Greece, and later Rome, until around 50 B.C. (6, page 2)

Pythagoras is perhaps the man responsible 
for bringing Egyptian and Babylonian
math, astrology, and medicine
to ancient Greece.


So this was the world that Pythagoras was born into in 570 B.C., give or take ten years.  Since nothing was written about him during his lifetime, all we know of him comes from second hand accounts after his death.  It's from these accounts that historians learned his dad was Parthenis, and that he was a descendant of the gods.  His mother was Mnesarchu.  (3, page 7-9)

They learned that an oracle at Pythian told Parthenis that his wife was pregnant with a child who would be blessed with great wisdom and who would be of great benefit to mankind. In recognition of the oracle, the child was named Pythagoras.  (3, page 7-9)

In his youth he must have spent quality time in the gymnasium at Samos, as he became a gifted athlete.  He was also a gifted student who loved to learn, and so must have listened to the stories of the orators, and the lectures of the sages.  At one point he listened to a lecture by the philosopher Phercydes about the "immortality of the soul," and he was "so charmed" that he dedicated the rest of his life to philosophy.  (1, page 81)

To satiate his quest to learn more he began his travels around the world, or so legend has it.  He first traveled to Meletus of Anatolia (modern day Turkey), which was at the time the home of philosophers.  While there he learned of the wisdom of three early Greek philosophers.  

Thales of Miletus was perhaps the first Greek Philosopher
1.  Thales of Meletus:  (624-546) He was a Greek citizen who lived in Meletus of Anatolia.  He is often credited as being the first philosopher and scientist.  He was the first who, instead of giving credit of all physical phenomenon to the gods, searched for the true cause.  He asked questions and searched for answers.  The answers were called theories. (3 page 12)

He traveled to Babylon and learned astrology, and used it to predict an eclipse of the sun.  He traveled to Egypt and learned from the Egyptian sages at Heliopolis.  He learned geometry and predicted the height of the pyramids using only its shadow.  He learned Egyptian medicine, which at the time was the best in the world. It's believed that he started the process of blending Egyptian medicine into Greek philosophy. (5, page 89-90)

He concluded that water was the primary element, and that all other elements were derived from it. By his observations he associated life with water.  Of this, historian Henry E. Sigeris said in 1987:
Thales had been in Egypt and saw the Fertilizing effect of water of the Nile that flooded the land periodically. He even ventured an explanation of this natural phenomenon, as Herodotus tells us.  Throughout the East he could see that life was bound to the presence of water.  Where water reached vegetation was abundant, and where it ceased, the desert began. Whatever was alive was moist, and Thales must have noticed that life-giving human and animal sperm was moist.  And so he came to believe that there was a casual relationship between water and life... when water evaporated, did it not become air? Such observations and speculations must have guided Thales in his assumption that water was the primary element.  (5, page 90)
Because of Thales, Meletus is often considered to be the birth place of Greek philosophy. (3, page 12)(5, pages 89-90)

Anaximander was among the world's first scientists, or, among the first
to question why things exist and to seek out answers by empirical means.

2.  Anaximander of Miletus: (611-546 B.C.) He became the pupil of Thales, and together he and his master were the first known philosophers, and therefore the first astrologers, scientists, mathematicians, and physicians. (3, page 12)

He did not believe, however, that water was the primary element.  Of him, Sigerist said:
He believed that the elements commonly thought to constitute the world -- water, earth, fire and air, with their qualities wet, dry, hot or cold -- were derived from one common indeterminate substance.  From this inexhaustible primary substance which 'includes everything in itself and guides everything,' two pairs of elements with opposite qualities were born, which seemed to be in ideal balance. In the beginning of the world these elements were separated with the earth in the center, and covered by a sphere of water. which was surrounded by air and ultimately fire. Everyday experience taught what happens when fire acts upon air, water, and earth. The earth became dry, water evaporated, pressure increased, and the ring of fire burst... Thunder and lightning were not the work of Zeus, but were caused in a perfectly natural way when air was compressed in a cloud and burst forth violently.  All living creatures originated in the water, and some became land animals when the water evaporated.  Man too arose from a fish-like creature. (5, page 91)
Sigerest said Aristotle said that Anaximander said "all things are full of gods."  In this way, Sigerist said, Anaximander began the transition away from believing everything was caused by gods, to the idea that they were caused by naturally occurring phenomena.  (5, page 91-92)

3.  Pherecydes of Syros:  (570-495 B.C.) He was among the first to rationalize Greek mythology.  In this way, he is credited as being the first to establish the idea that the human soul was immortal.  This type of thinking was taught by Pherecydes at the gymnasium of Syros, and it greatly impressed a young Pythagoras. (2)

It is then speculated that Pythagoras traveled abroad, to Egypt, Mesopotamia and India.  It's believed he spent 20 years in Egypt learning from its sages.  Some speculate he even became an Egyptian priest.  He then was taken to Mesopotamia and held captive for 12 years in Babylon. During his time there he learned from Mesopotamian sages.   (3, page 12-14)

Medical historian Max Neuburger said once his travels were done he settled in Crotona, which is now Southern Italy. He said:
(He) founded a guild in Crotona, religious and moral, did pioneer work, not only in mathematics, astronomy and acoustics, but in investigation of the structure of the body, reproduction and development, the functions of the senses and mental activity, as well as in the treatment of the sick. (8, page 105)
Neuburger also said that being that there was also an Asclepion in Crotona, physicians at the medical school at Crotona were probably constantly in touch with the Pythagorean followers, many of whom were physicians. So early on there was a mingling of the different schools of philosophy or medicine. (8, page 106)

His greatest interest was regarding religion, and so he preached that what was learned in this life could be used in the next life when the soul moves on to another body, or to the final resting place.  (3, page 25)

Some speculate he came up with this idea from Phercydes, although some speculate this wisdom came from the Egyptians, who likewise believed the soul traveled into the afterlife.  Although others speculate this wisdom came from the Indians, who believed in reincarnation of the soul, or that once you die you are reborn as another person.

His followers were interested in his ideas about religion, but they were also interested in all his philosophical wisdom.  While historians credit Thales as the first philosopher, Pythagoras was the first person to refer to himself as a philosopher during his own lifetime.

Again, we must understand that philosophy is the quest for knowledge.  So when Pythagoras, and all the later ancient philosophers, lectured, they preached all the wisdom of the day, which included  mathematics, science, astronomy, astrology, music, and medicine.  It wasn't until many centuries later that each of these were extracted from under the rubric or umbrella term philosophy to become natural sciences all of their own.

So by his lectures he shared this knowledge.  His fellow Greek citizens were so impressed that word quickly got out about all the knowledge of Pythagoras, and so he quickly developed a large following. Renouard said his followers became known as Pythagoreans Disciples, or simply Pythagoreans.

Pythagoras established these followers of his into "a well-disciplined school," said Henry Sigerist in his 1922 history of medicine. It was called the Pythagorean Order.  (5, page 94-95)

Renouard said his followers would often sell all they had to dedicate their lives to Pythagoras and the general good.  (1, page 83)  Sigerist said they ate a healthy diet in order to maintain a healthy balance, or equilibrium, within their bodies.

Neuburger said, according to Pythagoras: (8, page 107)
The body was formed from the warm, the breath causes cooling.The causes of disease are bile, blood and phlegm. Predisposition to disease are excess or lack of warmth, nourishment, etc. Inflammation arises from accumulation of phlegm -- in itself warmth producing. (8, page 107)
When they were sick it was because the equilibrium was disturbed, and it was only re-established "physically with medicine, and mentally with music. This was why both medicine and music were greatly cultivated in the Pythagorean school, " said Sigerist. (5, page 96)

Neuburger said:
Health, according to him was a condition upon the equilibrium of materials present in the body (cold, moist, warm, dry, sweet, bitter); sickness results through the predominance of one quality, cure from a restoration of the balance, through the addition of the opposite one. (8, page 107)
Neuburger said he neglected "most surgical procedures, and mostly employed the following as remedies: (8, page 106)
  • Simples
  • Poultices
  • Salves
  • Expiations
  • Spells
  • Magical herbs
  • Incantations
  • Religious music
  • Physical exercise (gymnastics)
  • Dietetic measures (such as limited consumption of meat) (8, page 106)
Renouard said Pythagoras taught a system of numbers that he probably learned from the Egyptians. (1, page 84)
"He designated God by the figure 1, and matter by 2; so he expressed the universe by 12, because this results from the juxtaposition of the figures 1 and 2."  (1, page 84)
Renouard said he explained the three distinct parts of life, or the three worlds: body, soul, and spirit.  So in this way the universe was in "harmony with the body and the soul," which, according to Pythagoras, were "manifested by three distinct faculties: sensibility, thought, and intelligence."  (1)

Renouard said Pythagoras introduced the Greeks to the significance of the number four.  He preached that there were "four spheres from which are formed each one of its three distinct worlds, (that) correspond to four elementary modifications of inert or amorphous matter. These primitive modifications are called fire, air, earth, and water, and are the elements which constitute all material substance." (1, page 84)

He was the first to establish the idea that the brain was the center of human intelligence. (8, page 106-107)(9, page 83)  This was a major step as far as medicine was concerned because physicians of neither Egypt nor Mesopotamia considered this fact.  Egyptians thought it was the heart, and Babylonians thought it was the liver.

He is also credited with creating the Pythagorean Therum, which states that the square of a hypotenuse of a right angle is equal to the sum of its squares. He is also credited with being the first to say the earth was a sphere, among other things.

We  must remember, however, that since most of what is known of him was told by second hand accounts after his death, much of what we know of him was probably exaggerated. Much of what was attributed to him was probably actually invented or discovered by one of his contemporaries or peers.  This was probably because Pythagoras lectured mostly in secret because much of what he taught was radical.  His followers were sworn to secrecy.  Perhaps this explains why Pythagoras was credited with all the wisdom of the Pythagoreans.  (3, page 20)(5, page 95)

Sigerist said that another reason for this was because "loyalty to the master impelled his student to attribute every contribution of any importance to him (Pythagoras)."

This was typical, however, of the ancient world, as most people were forced to, or in most cases willing to, make a humble contribution to the the collective.    (5, page 95)

Many historians also believe much of what he is credited with may even have been known for generations before he was even born, such as the pythagorean therum, which must have been known when anonymous architects were building many of the structures of the ancient world.  It may have been postulated by Egyptian mathematicians, or perhaps even by an anonymous sage from ancient Sumeria.

Pythagoras was well respected in life, although his ideas on mathematics were generally not accepted until well after his death.  However, the teachings of his school would influence many succeeding generations of Greek philosophers, including Plato and Hippocrates.  In fact, his teachings also continue to influence people to this day.

Pythagoras died sometime around 500 or 490 B.C., although his philosophy lived on for many years by his followers. They continued to lecture, and in this way philosophy was learned by many Greek citizens, including Plato and Hippocrates. In fact, his teachings continue to influence people even to this day.

Henry E. Sigerist, in his 1922 history of medicine, said that Pythagoras may simply have been a benefactor of the times he was born into, a time when Greek citizens were becoming better educated about the world around them.  He said:
Many people were no longer satisfied with the naive and primitive worship of the Homeric gods and felt shocked by the many scandals mythology reported about them. We saw that the cult of Asclepius developed in this atmosphere, as did a number of mystery religions under Asiatic influence. Pythagoras is one of the exponents of the great Orphic movement." (5, page 95)
So by the 5th century there was such a demand for wisdom that many of the gymnasiums were transitioned to places of learning, thus becoming the schools and universities. (4, page 39)

Many believe this system of associating education with a temple was learned from Egyptian and Babylonian sages, as both those nations had a similar system of learning.

The most famous of these Greek schools were associated with temples of the god Asclepius, who was the the messenger of the gods and capable of communicating their wisdom with the citizens of Greece.  These schools became known as Asclepions.

Renouard said these gymnasiums were "surrounded by halls and porticos where philosophers, rhetoricians, artists, and physicians assembled to hold their schools and dispute on questions of art." (1, page 80)

So with a lot of time on their hands, and a burning passion to learn, Greek citizens like Thales, Anaximander, Pherecydes and Pythagoras traveled the world in search of the wisdom of the sages.  What they brought back to Greece inspired its citizens, peeking their interest in philosophy.

It was Pythagoras, and Pythagoras alone, whether this is accurate or not, who is given credit for introducing ancient Greece to philosophy.  Of this, Renouard concludes that Pythagoras was: (1, page 90)
"The last celebrated example of distant peregrinations in search of wisdom..." (after him) "the sages of Greece ceased their journeys in search of light in foreign countries, for their own country became in its turn a center of illumination for all nations." (1, page 90)
Pythagoras gave rise to the Age of Philosophers.  This is key to our asthma history because without ancient Greek philosophy, modern medicine would be ages behind where it is today, if it existed at all.

639-322 B.C.: Greek medicine was key

While medicine existed within the confines of other ancient civilizations, it came to a culmination in ancient Greece, particularly during the Age of Philosophers. With slaves were doing all the work, Greek citizens had time to ponder about the world around them and search for answers.  They visited all the sages of the world, adding what they learned to the pantheon of Greek philosophy.

Among this wisdom was all that was known about medicine, and, in this way, during a period of only a few hundred years, Greek philosophy became the key to all medical wisdom.  Those who had access to it would have the best physicians in the world.  Those who did not would be left in the dark ages of medicine.

It all began with Thales of Miletus.

1. Thales of Miletus (639-544 B.C.): Garrison, in his 1922 history of medicine, said "he was taught under Egyptian priests, and taught that water is the primary element from which all else is derived." (1)

2. Anaximander of Miletus (611 B.C.): Garrison said "he mapped the heavens and made a successful prediction of an eclipse."(1) Perhaps he did this while working with Thales, because Sigerist credited Thales as accomplishing this feat. He believed the common elements were fire, air, water and earth, and their qualities were wet, dry, hot and cold. He believed they were all caused by a primary substance. From this the idea of two primary elements with opposite qualities was born. In a healthy person they were in balance. This theory would go on to become a significant part of Greek medical theory. (2, page 91) It must be assumed her that he did not create these elements and qualities, simply introduced them into Greek philosophy.

3. Pythagoras of Samos at Crotona (580-489 B.C.): Garrison said he studied in Egypt and it is probably from here that he "acquired his doctrine of the mystic power of numbers... (of which) the numbers three and four represent the worlds, the spheres, and the primordial elements" (earth, air, fire, water). He was also the first to associate the brain as the "central organ of higher activities." (1)

Sigerist said that while he believed in the elements and qualities, he believed the number was the most significant. He said:
Among the numbers, four played a significant part, for it seemed logical that two pairs of forces with opposite qualities would constitute an ideal balance, and we shall see that this view had a profound influence on medical theory, as had the Pythagorean doctrine of opposites of its dualistic form in general. These opposites were necessary to explain the harmony of the world. (2, page 97)
He believed that a balance of the internal qualities must be achieved in order to
maintain health, and this was maintained by "practicing moderation." When a person was unhealthy it was because the balance was disturbed. Health was therefore re-established physically by medicine, and mentally by music. (2, page 96-98)

Neuburger said some of the internal materials present in the body that needed to be balanced were cold, moist, warm, dry, sweet, and bitter. Empedocles would later limit these to four.   (13, page 107)

As can be assumed with some degree of accuracy, he basically compiled all the wisdom of the sages of the world, and all the wisdom of the earlier philosophers of Greece, and created a large following who listened to his lectures. He even organized his followers into a school, and in this way he made philosophy popular in Greece, and is often given credit for giving birth to the Age of Philosophers in ancient Greece.

You can read more about Thales, Anaximander, and Pythagoras in this post. (1)

4. Anaximenes of Miletus (570-500 B.C.): He lived about the same time as Pythagoras. Garrison said he "assumed that indivisible matter (earth?), air, or fire respectively are the primordial elements."(1) Sigerist said he believed that of the elements of earth, air, fire and water, that air was the primary element. Of this, Sigerist said: (2, page 92)
He wrote a book of which one sentence has survived: "As our soul, being air, holds us together, so do breath and air surround the whole universe." (2, page 92)
He believed air was essential for sustaining life, and that it was also evident in the soul. He believed air was the primary element because he believed the others were "born from it through changes of density," said Sigerist, "through rarification (decrease in pressure) and condensation (increase in pressure)." (5, page 92)

Sigerist continued, "Rarified air became fire, and heat was generated in the process, while condensed air became water and finally earth, and produced cold. This was a logical explanation, and breath or air came to play an increasingly important part in biology." (2, page 92)

5. Heraclitus of Ephesus (556-460 B.C.): Similar contributions as Anaximenes.(1) Sigerist said he believed everything changes constantly, and therefore he believed the primary element was fire because it causes things to change. He believed fire produced air, water and earth. Fire, like war, causes strife, and the polar opposite of war and fire causes peace and unity (or balance).

Sigerist quotes him as saying: (2, page 93)
That which is in opposition is in concert, and from things that differ comes the most beautiful harmony." (2, page 93)
Sigerist said that, quoting Heraclitus along the way, "It is through opposites that we become aware of things. Disease 'makes health pleasant; evil, good; hunger, plenty; weariness, rest.' And everything in the world moves according to eternal laws. These very principles, unity of the world, eternal changing of all things caused by tension, and law and order ruling the world, were principles which proved to be strong stimulants to scientific research." (5, page 93-94)

6. Anaxagorus of Clazomenae (500-428 B.C.): He assumed the four elements (earth, air, fire, water) to be made up of as many parts or 'seed' as there are varieties of sensible or perceptible matter. (1)

7.  Empedocles of Agrigentuin in Sicily (504-443 B.C.): Medical historian Edward Withington said he first mentioned the four elements, which would later influence Greek medicine, in the following poem:  (7, page 45)
Listen, first, while I sing the four-fold root of creation,
Fire, and water, and earth, and the boundless height and the aether, For therefrom is begotten what is, what was, and what shall be. (7, page 45)
Withington explained that by... 
"...substituting air for aether, this is the doctrine of the four elements, which Empedocles introduced into philosophy, and which, with the co responding four qualities, heat, cold, moisture, and dryness, and the four humours, blood, phlegm, black and yellow bile, lies the basis of Greek medical theories." (7, page 45)
Fielding Hudson Garrison verifies this, adds to its significance.  He said:
"He introduced into philosophy the doctrine of the elements (earth, air, fire, water) as 'the four fold root of all things.'  The human body is supposed to be made up of these primordial substances, health resulting from their balance, disease from imbalance.  He holds that nothing can be created or destroyed, and that there is only transformation, which is the modern theory of conservation of energy.  Everything originates from the attraction of the four elements and is destroyed by their repulsion, and he applies the same idea, under the forms of love and hate, to the moral world.  Development is due to the union of dissimilar elements, decay to the return of like to like (air to air, fire to fire, earth to earth)." (1, pages 80)
The association between the four elements, four qualities, four humors, four basic organs, four seasons, and the four personalities can be seen by the following chart.

You will see the significance of these played out in pretty much any history of mankind, and definitely in any history of medicine.  While some contribute these to various different authors (Aristotle sometimes gets credit for the four elements, and Hippocrates for the four humors), it is the great Empedocles to which they may all be traced back to.

He believed that respiration, along with occurring through the lungs, also occurred through tiny pores in the skin.  (13, page 108-109)

While Empedocles probably wasn't the first to conceive of the idea that something in the air inhaled was essential to life, he created the theory of pneuma.  Pneuma was a substance in the air that contained a vital spirit.  It flowed through the body by veins, providing life to the organs.  It was responsible for movement, consciousness and perception.

8,  Democritus of Abdera (460-370 B.C.):  He was a student of Leucippus, and believed the mind and body were composed of corpuscles or atoms that were solids and unchangeable.  In this way, he believed living things were made of these solid atoms as compared to the humours of Hippocrates.  (14)

He believed the atoms were organized and arranged within the human body by a natural mechanism. (8, page 23)  He believed that inflammation was an accumulation of phlegm.  He believed the "widespread appearance of epidemic disease was... due to the disseminated atoms of shattered heavenly bodies." (13, page 110)

9.  Hippocrates (460-370 B.C.):   Prior to Hippocrates, methods of treating diseases were relatively simple, and taught mostly by word of mouth.  However, stored in the Asclepions were votive tablets, and these contained lists of diseases and their cures.  Hippocrates was the first to take all this wisdom and publish it into a compilation of 60 treaties called the Corpus Hippocraticum.

He believed air was inhaled, and this air contained pneuma.  He actually referred to "breath" as the pneuma, and this pneuma (or breath) flowed through the veins, such as was noted by Empedocles.  In health its flow through the body was unimpeded.

He believed that within each person was a combination of the following qualities: (14)
  • Acid
  • Saline
  • Acerb
  • Bitter
  • Mild
  • Insipid
  • Austere (14)
He said each of these was...
...possessed of different powers, in proportion to their quantity and degree of strength. All of these, when well united, and tempered by each other, are insensible to us, and do no injury; but if one should separate, and exist alone, it then becomes sensible, and ravages the system. It is the same with aliment. That which is improper for us, is either bitter, saline, acid, or too strong. (14)
Healthy food, such as bread, barley and cakes, "causes no uneasiness, or any separation of the particles of the humours of the body, and serving only to strengthen, nourish, and promote its growth. All these benefits arise from its well-attempered state, in which nothing predominates, nothing is irritating, nothing too strong. Every thing is reduced to a point, so as to be esteemed simple, homogeneous, and at the same time, of adequate strength." (14)

However, in the process of making such food, things like fire and water are employed, "each having its own peculiar powers and qualities. (The food) loses part of what it had, and what remains is a compound mixture." (14)
In this way, each type of food has its own particular qualities, such that bread has different qualities than cakes. Likewise, depending on how it was prepared, two different loaves of bread may have unique qualities. (14)

Hippocrates believed, therefore, that eating the wrong food, or too much of the good food, or food that was not prepared correctly, or food that was not part of that person's normal diet, might upset the unity and homeostasis within the body. This, in turn, leads to changes in the four qualities and four humors of Empedocles.

Medical historian Edward Meryon said Hippocrates must have studied the works of Democritus, who believed that a natural process usually worked to maintain a balance (homeostasis, unity) of the atoms.  Hippocrates believed a natural process usually worked to maintain four qualities and four humors of Empodocles in order to maintain health.  Hippocrates taught that any imbalance of the qualities or humors within a person was the cause of disease.  (8, page 23)

Nature worked to maintain balance in health, and to re-establish balance in sickness.  He believed imbalances were generally the result of eating the wrong foods, or changes in the wind, or changes in the temperature, or changes humidity.

His remedies were generally gentle, and merely worked to assist nature in the healing process.  They included simple things such as getting plenty of sleep, taking a bath, eating healthy, and exercise.  

He believed in the maxim:
"Merely give nature a chance, and diseases will cure themselves."  (3, pages x-xii)
His ideas would transform medicine from one of mythology and philosophy taught at the Asclepions, to a "distinct department of practical knowledge" that could be learned by anyone.  (9)

10.  Plato (427-347 B.C.):  He was a student of Socrates, and became famous for recording the wisdom of the great philosopher.  He then became a famous philosopher himself.  As was normal for the era he was born into, he was educated in all the knowledge of the day, including medicine.

Garison said that his main contribution to medicine was that "In pathology, the plastic significance of the number four was combined with the doctrine of the four elements." This can be seen here (in parenthesis is our modern correspondence): (1)
  • hot + dry = fire (hydrogen)
  • cold + dry = earth (oxygen)
  • hot + moist = air (carbon)
  • cold + moist = water (nitrogen) (1)
These could also result in the following:
  • hot + moist = blood
  • cold + moist = phlegm
  • hot + dry = yellow bile
  • cold + dry = black bile
The various combinations of these resulted in both the aspect of disease and the action of the drugs used to treat them.  Each person had a unique combination of these and maintained the equilibrium in times of health. Disease was a result of increases and decreases of any of the above.  Health was re-established by making the necessary adjustments.  (1)

Plato believed in the Pythagorean Theory of Opposites, although he also believed there was a "third element mediating between a pair of opposites." He believed the soul completed "the human trinity of body, soul and spirit."   (12, pages 2-4)

He believed the body consisted of a soul with three parts: (11, page 23)
  • Rational Soul: Created by the brain 
  • Animal Soul: Created in the chest and is responsible for emotions and passions
  • Vegetable Soul: Created in the abdomen and controlled physiological needs (11, page 23)
While Plato didn't create any of these ideas, he helped to keep them alive by his fame.  He would also relay this wisdom to his famous pupil, Aristotle.   

11.  Aristotle (384-322):  He was born in Stagira to a wealthy family. His father, Nicomachus, was personal physician to Amyntas, king of Macedon.  He probably learned quite a bit about medicine from his father before being instructed by Plato when he was 17.  (6, page 3)

He would spend about 20 years in Athens as a student at Plato's academy, and then as a teacher. Some speculate he left after not being chosen as Plato's successor upon Plato's death in 347 B.C.  Some speculate the reason Aristotle was not chosen, and why he left Athens, was because Aristotle was known to debate and disagree with Plato.  He moved from Athens and continued his work elsewhere. (6, pages 3-5)

Regardless, he basically supported the same ideas regarding medicine as Plato. He believed in the four elements, qualities, and humors. He believed that a balance or imbalance of these determined health and sickness.  (1)

While he believed in the elements of Empedocles, he attempted to add a fifth element that he called aether, a substance that made up what was seen in the sky at night, such as the stars, sun, planets, comets, etc.  He was not the first to write about the elements and their qualities, although by the fame he acquired by being the instructor of Alexander the Great, he was able to increase public awareness of them.

While he was not a physician, and is known mainly for his contributions to philosophy, he did make some significant contributions to medicine.  Considering he was unable to dissect human beings, he spent most of his time at the dissecting table studying plants and animals.  He was known for his faith in nature, claiming that "Nature does nothing uselessly."  (5)

12. Erasistratus (304-250 B.C.)  He was among the first Greek anatomists.  He was the beneficiary of the new city, Alexandria, created by Alexander the Great. After Alexander died before he was 32 years old, Ptolomy decided to make Alexandria the leading place of wisdom and science in the world, so he gave the physicians at Alexandria permission to dissect human beings.  Among these physicians was Erasistratus, who discovered and learned much about the inner workings of the human body.  Some say he even went as far as to dissect living human beings, but all in the name of advancing science and wisdom.

He disregarded the idea the four humors caused disease, and believed that diseases like pneumonia were caused by changes in the body, such as inflammation of the lungs.  This is the type of wisdom that might have been expounded upon if it wasn't considered sacrosanct to dissect the human body through much of the ancient world.

13. Herophilus (335-280 B.C.): He was the other leading physician at the school of Alexandria, and he likewise participated in dissection of the human body in a quest to improve wisdom and science. Unlike Erasistratus, he supported Hippocrates and his humoral ideas.

14.  Galen:  He was born during the Roman Civilization, although he still lived in Greece.  He lived in Pergamum, a city that was ruled by the Romans, but that still lived under Greek culture.  Galen learned from all the above physicians, and he basically combined the works of all these great men, particularly combining the theories of Hippocrates with the anatomical discoveries of Erasistratus and Herophilus.

He believed in the humoral theories of health and sickness of Hippocrates. However, while Hippocrates was not concerned with anatomy of the body, Galen came up with theories of how each organ participated in the organisms life giving process.

Galen also believed in the Aristotelian idea that nature makes no flaws, and perhaps from him Galen obtained his belief that God created only perfect human beings, and therefore each part of the body had a perfect function.

Through his writings he described the faculties of nature, whereby each part of the body (veins, arteries, organs, etc.) performed a distinct function in order to maintain life, health and longevity.

He absorbed the idea of Plato of the power of three parts of the soul, although he referred to them as spirit.
  • Natural Spirit: Formed in the liver and flowed through the body by veins to the various organs. 
  • Animal Spirit: Formed in the brain and responsible for sensation and intelligence
  • Vital Spirit: Formed in the heart when air mixed with blood, and flowed through the arteries to the various organs.  It consisted of passions. 
He believed the person ingested food, the food was cooked in the stomach, turned into chyle, sent to the liver by veins, and turned into blood in the liver.  The liver added natural spirit and nutrients to the blood, and sent it to the right ventricle of the  heart to be purified.  The blood was turned into a light, frothy substance so it could enter the lungs, and returned to the right ventricle of the heart as purified blood that ebbed and flowed through the entire system to provide natural spirit and nutrients to the body through the veins.

Some blood from the right ventricle was transferred to the left ventricle by invisible pores. This blood was mixed with air that was inhaled by the lungs. Since the heart was hot and controlled the temperature of the body, the cool air was needed to cool the heart. Air also contained pneuma, and so when the air and pneuma mixed with blood in the left ventricle, it formed vital spirit. This substance was responsible for the passions of the person, and was transferred through the body by the arterial system.

Some arterial blood went to the brain by vessels from the heart to the brain.  Here this blood was mixed with animal spirit and sensations and intelligence.  These were transported through the body by the various nerves.

His ideas of health and healing were similar to Hippocrates, although he believed changes that occur within one organ can effect the body as a whole.  For example, asthma was caused by increased phlegm in the lungs, epilepsy was caused by increased phlegm in the brain, fever was caused by increased blood, etc.

His remedy was to treat contraries with contraries, or to treat whatever was the suspected cause with the opposite.  If someone has too much phlegm, for example, Galen may have the patient drink a purgative or emetic to expectorate the excess phlegm.

Since Galen was the very last of the Greek and Roman physicians when Rome collapsed, and because he wrote so much about it, his works continued to be worshiped for greater than the next 1,500 years.  Basically, Greek medicine survived the dark ages through the works of Galen.

During the Middle Ages the Catholic Church accepted the medical writings of Galen, perhaps because he believed that God created only perfect human beings. This fit into the Christian belief that god made no flaws.  During this time, anyone who spoke out against the writings of Galen was greatly ridiculed, and sometimes severely punished, sometimes with death.  (4, page 113)

So during the dark ages of medicine, Galen became a god, of sorts, of medicine. His works were like the Bible to physicians. In this way, Greek medicine was the key, or the foundation of all medical knowledge. It would only be from using this key that any future advancements in medicine would be made.
