Vitalism
This article is about the non-mechanist philosophy. For other uses, see vitalVitalism is the doctrine that
"life forces" are active in
living organisms, so that life cannot be explained solely by
mechanism. That element is often referred to as the "vital spark", "energy" or "
élan vital", which some equate with the "
soul". Vitalism has a long history in
medical philosophies. Most traditional healing practices posited that disease was the result of some imbalance in the vital energies which distinguish living from non-living matter. In the Western tradition, these vital forces were identified as the
humours; eastern traditions posited similar forces such as
qi,
prana, etc. Vitalism is largely seen as pseudoscientific (Williams et al 2000).
Aided by the invention of the
microscope in the
16th century, the
germ theory of disease gained momentum and challenged the role of vitalism in Western medicine.
Attention was also drawn to the role of the various organs of the human
anatomy, as opposed to vital forces, in the maintenance of life.
Experiments in the early
19th century continued to erode support for vitalism in the Western
scientific community, beginning with
Carl Reichenbach's theory of the
Odic force. As an implication of vitalism,
organic compounds were thought to be only produced by living organisms, as a byproduct of the presence of the vital forces. However, as chemical techniques advanced, it was found that many of these compounds, such as
urea, could be produced using the same types of
chemical processes that produced inorganic compounds.
Further chemical and anatomical discoveries pushed aside the "vital force" explanation, as more and more life processes came to be described in purely scientific terms, and as the medical model of disease came to be more and more focused on the failure of particular organs and processes in the body.
Vitalism in medicine (and more generally, in society) experienced a resurgence beginning in the late 20th century. Although scientific understanding of the
biochemical processes which distinguish living from non-living matter has become increasingly sophisticated, so has the realization that these fundamental processes are incredibly complicated; no complete,
reductionist theory has yet been proposed which coordinates all of the actions which occur in a single
cell (let alone a higher organism). Just such a thing, however, is an explicit goal of several currently working molecular biologists, some of whom speak of elucidating the complete "wiring diagram" of a living cell. Vitalism is a key aspect of many alternative medicines, and is often considered pseudsocientific (Williams et al 2000).
Sometimes a division between
soft vitalism and
hard vitalism may be drawn. The former have a vitalist world-view but employ common
scientific methods in their conduct, stating that their
metaphysical ideas have nothing to do with their work. The latter is the category usually identified with vitalism, clearly stating that life processes are radically different from the processes in non-living matter.
Modern medical vitalism, as represented by such schools as
homeopathy,
naturopathy,
acupuncture,
anthroposophy,
biodynamic agriculture and
chiropractic, tends to emphasize a
holistic approach to the cause and treatment of disease.
In terms of the
biology of the cell itself, a return to vitalism is seen in the proposal that life is an
emergent process which cannot be accurately described simply by understanding any number of chemical processes which occur in the cell.
