Vitalistic thinking has also been identified in the naive biological theories of children. The notion that bodily functions are due to a vitalistic principle existing in all living creatures has roots going back at least to ancient Egypt.
These two forms of matter were termed organic and inorganic. Inorganic matter could be melted, but could also be restored to its former condition by removing the heat. Organic compounds "cooked" when heated, transforming into new forms that could not be restored to the original. It was argued that the essential difference between the two forms of matter was the "vital force", present only in organic material.
Aided by the invention of the microscope in the 16th century , the germ theory of disease challenged the role of vitalism in Western medicine, and the roles of the organs of the human anatomy in the maintenance of life became better understood, reducing the need to explain things in terms of mystical "vital forces". Nevertheless, vitalist ideas were still thought necessary by many scientists to explain how organisms maintained life.
Carl Reichenbach later developed the theory of Odic force , a form of life-energy that permeated living things; this concept never gained much support despite Reichenbach's prestige.
Vitalism is now often used as a pejorative epithet. It would be ahistorical to ridicule vitalists. When one reads the writings of one of the leading vitalists like Driesch one is forced to agree with him that many of the basic problems of biology simply cannot be solved by a philosophy as that of Descartes, in which the organism is simply considered a machine….. The logic of the critique of the vitalists was impeccable. But all their efforts to find a scientific answer to all the so-called vitalistic phenomena were failures.
No complex system can be understood except through careful analysis. However the interactions of the components must be considered as much as the properties of the isolated components. A popular vitalist theory of the eighteenth century was " animal magnetism ", in the theories of Franz Anton Mesmer — The commissioners learned about Mesmeric theory, and saw its patients fall into fits and trances. The commissioners concluded that "the fluid without imagination is powerless, whereas imagination without the fluid can produce the effects of the fluid.
In the history of chemistry, vitalism played a pivotal role, giving rise to the basic distinction between organic and inorganic substances, following Aristotle's distinction between the mineral kingdom and the animal and vegetative kingdoms. According to the conventional view of the subsequent progress of chemistry, further discoveries pushed aside the "vital force" explanation, as more and more life processes came to be described in chemical or physical terms.
Some of the greatest scientific minds of the time continued to investigate these vital properties. Louis Pasteur , shortly after his famous rebuttal of spontaneous generation, made several experiments that he felt supported the vital concepts of life. According to Bechtel, Pasteur "fitted fermentation into a more general programme describing special reactions that only occur in living organisms.
These are irreducibly vital phenomena. He found no support for the claims of Berzelius, Liebig , Traube and others that fermentation resulted from chemical agents or catalysts within cells, and so he concluded that fermentation was a "vital action".
Perhaps more than any other area of science, psychology has been rich in vitalist concepts, particularly through the ideas of Sigmund Freud and Carl Jung. Freud was a student of the notable anti-vitalist Hermann von Helmholtz , and initially struggled to express his concepts in strictly neurological terms.
Abandoning this effort as fruitless, he became famous for his theory that behaviour is determined by an unconscious mind , of which the waking mind is unaware. In , in The Ego and the Id , he developed the concept of " psychic energy " as the energy by which the work of the personality is performed.
Although Freud and Jung remain hugely influential, psychology has made a determined effort to rid itself of the most mystical of these concepts in an attempt to appear more like the "hard" sciences of chemistry and physics. The events of inner experience, as emergent properties of brain processes, become themselves explanatory causal constructs in their own right, interacting at their own level with their own laws and dynamics.
The whole world of inner experience the world of the humanities long rejected by 20th century scientific materialism , thus becomes recognized and included within the domain of science.
Anti-reductionism has been identified as a problem in psychology. Thomas states that "It is now generally considered that biology had to rid itself of vitalism to enable significant progress to occur. It is suggested that psychology will develop as a science only after it rids itself of anti-reductionistic, 'emergentism'. Caspar Friedrich Wolff is considered to be the father of epigenetic descriptive embryology.
In his Theoria Generationis , he endeavoured to explain the emergence of the organism by the actions of a "vis essentialis", an organizing, formative force, and declared that "All believers in epigenesis are Vitalists. Blumenbach cut up freshwater polyps and established that the removed parts would regenerate; he inferred the presence of a "formative drive", an organic force, which he called "Bildungstrieb". He pointed out that this, "like names applied to every other kind of vital power, of itself, explains nothing: it serves merely to designate a peculiar power formed by the combination of the mechanical principle with that which is susceptible of modification.
Vitalism was also important in the thinking of later teleologists such as Hans Driesch This comment came from his experiments on sea urchin eggs. Driesch, already a famous biologist, became a vitalist, but his reputation as a biologist deteriorated in later life. While conventional medicine has distanced itself from the less reductionistic and more vitalistic approach of traditional medicine , some complementary medical fields continue to espouse various guises of vitalistic concepts and worldview.

This theory was disproved when Friedrich Wohler made urea an organic compound from ammonia an inorganic compound.
Who believed in vitalism? Louis Pasteur was a French microbiologist and chemist and he was famous for his discovery of the principles of pasteurization, microbial fermentation and vaccinations.
What makes a compound organic? Organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides. What compound did Wohler produce? What was Aristotle's vital force? Vitalism, school of scientific thought—the germ of which dates from Aristotle—that attempts in opposition to mechanism and organicism to explain the nature of life as resulting from a vital force peculiar to living organisms and different from all other forces found outside living things.
What is the function of artificially synthesized urea? Synthetic urea is created from synthetic ammonia and carbon dioxide and can be produced as a liquid or a solid.
