It was one of their professors, Georg Ernst Stahl (1660-1734), who first reintroduced the ancient idea of the vital force in the form of the "anima sensitiva" which is derived from the Greek words for the sensitive soul.
Stahl's theory is called mono-dynamism because he postulates that the anima is the sole force behind all the activities of the organism in the state of health and disease.
Stahl taught that the nervous system was a network that the vital force used to transmitted its impulses of the vital energy around the various centers of the body.

Stahl was the originator of the phlogiston theory, which dominated chemistry until the end of the eighteenth century.
Stahl elaborated from Becher's "second earth" a new chemical principle, phlogiston, a substance representing the principle of combustibility that combined with other chemical substances to form compounds.
Stahl was proud, morose, and atrabilious; he rarely answered letters; he showed contempt for all who differed from his views and reacted violently to criticism.

Stahl, Franklin W. American geneticist who (with Matthew Meselson) elucidated (1958) the mode of replication of deoxyribonucleic acid (DNA; the gene substance), a double-stranded helix that dissociates to form two strands, each of which directs the construction of a new sister strand.
The German dramatist Georg Büchner exercised a marked influence on the naturalistic drama that came into vogue in the 1890s and, later, on the expressionism that voiced the disillusionment of many artists and intellectuals after World War I. He is now recognized as one of the outstanding figures in German dramatic literature.

 Ancients & Alchemists: Faces—The Human Dimension
Some may think it a dubious honor to go down in history as the founder of a discarded theory, but Georg Ernst Stahl’s development of phlogiston theory was an important milestone in the development of modern science.
Though Antoine-Laurent Lavoisier would later show that combustion was really the chemical combination of a material with oxygen, and calcification the combination of a metal with oxygen, Stahl’s phlogiston theory represented one of the first attempts to develop a formal theory of how a chemical process took place based on observations.
He became a professor of medicine at the University of Halle when that school was founded in 1693, due to his friendship with Elector Frederick III of Brandenburg, and later moved to Berlin as a court physician.

It is ironic that the views of the physician Stahl were mystical, dogmatic and unsupported by anything but stubborn insistence on the logical consequences of his reasoning, based on what this writer considers to be nonsensical assumptions.
According to Stahl, all emotions implied a need to acquire some psychological goal which in some way becomes united with an external object ("introjection" in today's terminology); the emotion, to be satisfied, might require rejecting or escaping from some external object.
Stahl also supposed two opposite propensities in the human body, one constantly and uniformly tending to corruption and decay, the other to life and health.

 Phlogiston Theory   (Site not responding. Last check: 2007-10-20)
According to the phlogiston theory, propounded in the 17th century, every combustible substance consisted of a hypothetical principle of fire known as phlogiston, which was liberated through burning, and a residue.
The word phlogiston was first used early in the 18th century by the German chemist Georg Ernst Stahl.
Stahl declared that the rusting of iron was also a form of burning in which phlogiston was freed and the metal reduced to an ash or calx.

Stahl postulated that ash from burnt wood and calx from heated metals are devoid of phlogiston, and heating calx with phlogiston-rich charcoal yields metal by calx re-absorbing phlogiston.
Though incorrect, Stahl's theory greatly facilitated the shift from alchemy to Antoine Lavoisier's new chemistry.

Georg Ernst Stahl (1660-1734), proposed that there was a combustible constituent or phlogiston (as Stahl named it from the Greek word for burned, or inflammable).
When a metal was heated it left a calx (oxide) and so a metal was considered as a compound of its calx with phlogiston.

One of these, the Animists, had for its chief exponent Georg Ernst Stahl of "phlogiston" fame; another, the Vitalists, was championed by Paul Joseph Barthez (1734-1806); and the third was the Organicists.
Hence in fever the pulse is quickened, due to the increased activity of the soul, and convulsions and spasmodic movements in disease are due, to the, same cause.
By many this theory is regarded as an attempt on the part of the pious Stahl to reconcile medicine and theology in a way satisfactory to both physicians and theologians, but, like many conciliatory attempts, it was violently opposed by both doctors and ministers.

The first step toward a theory of chemical reactions was taken by Georg Ernst Stahl in 1697 when he proposed the phlogiston theory, which was based on the following observations.
Stahl explained it by suggesting that the weight increased because air entered the metal to fill the vacuum left after the phlogiston escaped.
The phlogiston theory was the basis for research in chemistry for most of the 18th century.
