The healing force of nature, vis medicatrix naturae, was a guiding
principle of ancient Greek medicine. It protected the patient during disease
and determined his prognosis. The physician's task was to assist the healing
force during treatment. To modern medicine, the healing force stands for unspecified
processes operating in disease. It has lost its appeal since technology brought
about astounding medical achievements and profoundly changed medical practice.
Technology has also revealed that diseases evolve. While ancient diseases
fell upon the patient, modern diseases start as silent aberrations which gradually
emerge. With advancing technology, more and more silent aberrations are detected
while medicine lacks clear guidelines as to how to deal with them. Is an arteriosclerotic
plaque a disease that should be treated, or an aberration whose treatment
may be postponed? How to deal with slight hyperglycemia, or minimal blood
pressure elevation? Medicine has reached a conceptual impasse. While competent
at specifying how to treat, it generally fails to decide correctly when to
intervene (1).
Wisdom of the Body
The answer to these questions is given by the organism itself whose wisdom
directs diseases along their course (1). The Wisdom of the Body anticipates
diseases and directs the healing force in health and disease. It aims
at improving health. Health is represented here by a simpler concept: tolerance,
which can be estimated. Disease lowers tolerance, and correct treatment, improves
it. An aberration should be treated only if improving tolerance. Tolerance
estimation is therefore crucial for correct treatment. We shall be concerned
mainly with the direction of tolerance, whether it improves or deteriorates,
and less with its exact magnitude. The direction of the tolerance can be estimated
from the behavior of the healing force.
Norm and State
All components of the organism are its norm. The healing force continually
adjusts the norm to improve tolerance. Since most components are not observable,
we shall restrict our attention to measurable components, or the state of
the organism. Blood sugar, for instance, is such a component upon which the
healing force acts. Its level is defined as blood sugar state. So are other
factors, e.g., insulin, glucagon, ketosis, or apprehension. The intensity
of each can be expressed by a number, and the collection of these numbers
is the state of the organism. These values are continually adjusted by the
healing force to keep the overall state at its most optimal norm, or best
tolerance. The healing force might be likened to a conductor directing an
orchestra. While the conductor aims at aesthetics, the healing force aims
at optimality, or tolerance. Both are normative.
Treatment
Treatment should improve tolerance. Since the healing force manipulates
the entire norm, what appears optimal to us may be less optimal to the organism
as a whole. When treating a patient with insulin we aim at lowering blood
glucose to its non-diabetic level, which might be harmful since it lowers
tolerance. As disease progresses, the organism creates new norms which have
to be considered during treatment (2, 3). The diabetic norm might require
a slightly elevated blood sugar. Since only the healing force adjusts components
of the organism normatively, normative treatment can be achieved only by assisting
the healing force. This is the main therapeutic implication of the healing
force concept. It is a guideline for "normative treatment" (4). In
order to apply it we ought to explore ways of measuring the healing force.
F=ma
Science provides a means for dealing with vague concepts like the healing
force. Gravity, for instance, is as obscure as the healing force. Its
intensity can be deduced from its effect on the motion of objects. This is
the essence of Newton's formula F=ma. Given a body with a mass m whose velocity
is constant, a force F accelerates the velocity of m by a. This equation
links an obscure force with a measurable effect, acceleration. The greater
acceleration the stronger the force and vice-versa. We could apply the same
reasoning to the healing force. Let m be the state of the organism
represented by a list of component values. In the above example m is the state
of the diabetic patient; m = {blood sugar level, insulin level, glucagon level,
apprehension intensity, . . .}. Let F stand for the healing force,
'a' will express the change of each component in the list m during a time
instant. If the equation is applicable we might be able to estimate the
healing force F from the instantaneous change of components in the list m.
When a increases, the condition of the organism improves and when it declines,
tolerance is deteriorating. In this example 'a' is related to normativity.
Mathematics of medicine
This example illustrates how it is possible to define
healing force mathematically. The equation F=ma and its ramifications spurred
mathematical development during the last centuries and this wealth may now
be applied to evaluating the healing force. On the other hand, is it valid?
Is it appropriate to apply Newton's equation to a "force" that does not exist
in the physical world? Nor does it resemble any known physical force, e.g.,
gravity or electromagnetism. The name might be misleading; we could as well
call it "Act of God", or élan vital. Would this make F=ma meaningless?
Not at all! Changing the healing force's name does not obviate the validity
of the equation since "Act of God" or élan vital may still be estimated
from the acceleration of the components in the value list m. The equation
is valid as long as it can be applied for the benefit of the patient. Mathematics
is only a language and may be applied for describing unrelated phenomena in
the same way as our numbering system is applied to counting apples or oranges.
Chaos
This example highlights yet another facet of the equation F=ma. While Newton's
original equation is linear and can be solved with modern mathematics, its
medical counterpart, is non-linear and chaotic, and cannot be solved by modern
mathematics. The first rudiments for its solution are found in Chaos theory
(5-8).
