Vital Energy (1931)

In homeopathy we are more particularly concerned with dynamic energy. This dynamic energy Hahnemann called the dynamis, the spirit-like, vital force animating the material body. …

A thorough understanding of the subject of energy is a necessary foundation for the study of homeopathic philosophy, if the student is to understand the principles upon which the practice of Hahnemannian homeopathy is based.

Energy, as we understand it, is of a three-fold form, spiritual, dynamic and physical. In practical application we think of the source of energy as being a thing upon which we can draw. We draw upon spiritual energy, upon dynamic energy, upon physical energy. Because we speak of three forms of energy we do not mean that they are essentially different. They are not. The different forms shade insensibly into each other. Energy is a store-house of vitality which exists in all nature and it shall be our special effort to so train you that you may avail yourselves of the power which we call energy.

In homeopathy we are more particularly concerned with dynamic energy. This dynamic energy Hahnemann called the dynamis, the spirit-like, vital force animating the material body. In the human body we have present all three forms of energy, the physical in the tissues, the dynamic in the brain and nervous system, and the spiritual in the mind. This dynamis of the human organism inter-penetrates each and every physical tissue of the body, it does not sit apart and superintend the actions of the tissues and organs. It is the thing, the power, the force, upon which we depend for reaction. This brings us down to the practicality of taking advantage of this dynamic energy in our homeopathic prescribing. All energy, in its essence, consists of action and reaction, and this action and reaction are equal and opposite.


Now we come to the practical application. Disease, as we ordinarily understand it, originates in a disturbance of this dynamic energy. The harmony under which the vital, dynamic energy usually operates becomes disturbed. Its pace, its rhythm, its rate of vibration become changed in one way or another, and this disturbance reflects itself outwardly by means of symptoms. The appearance of the external symptoms is a manifestation of the internal storm. In speaking of these external manifestations we are not speaking of symptoms of arteries, of muscles, or of mind, but rather of universal symptoms shown in every part of the body, for the sick patient shows distress as a unit, and not as separate, single discrete changes or actions. Let us look upon disease as a unit of action moving in a certain direction, destined though it be. We must remain within the rhythm peculiar to our own vital force.- That rhythm is normally paced between certain limits and when these are overstepped, heightened beyond the normal or lowered under it, we have sickness. Thus sickness is a disturbance of the rhythm of the vital force, either increasing or lowering it, and such sickness is manifested by external symptoms.

In drawing upon this store-house of dynamic force within us we are also calling upon another force which acts almost synchronously with the disturbed vital force of the human body. If the pace were exactly synchronous there would be no effect. It acts by modifying the disturbing force by changing its rhythm. For example, in the case of a runaway train an engine is not sent in the opposite direction (allopathy) but in the same direction, following it. This engine or force acting in the same direction (homeopathy) changes the speed (pace) and rhythm of the runaway and checks the train (disease).

Symptoms show themselves in just the order above outlined, mental, dynamic, physical, but not every patient shows all symptoms in all three classes. One patient may show symptoms in the mental sphere, another in the dynamic sphere, and yet another in the physical sphere. Every patient will show some symptoms from all three spheres if careful search is made for them, but the symptoms shown will be more prominently marked in some one particular sphere.


Disorder or disturbance of the dynamis is called sickness, illness, disease, not at ease. This not being at ease presupposes some disturbance somewhere, which disturbance originates in the dynamic force of the body and restoration to order presupposes restoration of the normal dynamic action first and the physical afterwards. The dynamis of the body is resilient, just as a rubber ball pressed in on one place bulges in another. Distress, disease, injury of any part of the body shows in some other part. Allopathy attributes this to the reflexes. This disorder is disharmony, and to restore harmony a similar acting force must be applied. Such similar forces are of various kinds but the most similar and the best known at the present day is the potentised homeopathic remedy. How do we know this? We know it because the potentised drug when given to a well person, one without disorder, produces symptoms of disorder in the dynamis, and these symptoms represent distress, disturbance, picturing disease of one kind or another. We know it because the similar potentised remedy, administered to a sick person, tends to establish equilibrium and brings about a smoothness of action, a restoration to orderly action in the sick person. This constitutes the only logical and philosophical explanation of our homeopathic remedies ever expounded. Even that great philosopher, Emerson, recognised this to be true and whenever it was necessary called only a homeopathic physician.
