Organon §15

The life force and the material organism form an indivisible whole, as do the mistunement of the life force and the complex of perceptible symptoms.

The suffering of the morbidly mistuned, spirit-like dynamis (life force) enlivening our body in the invisible interior, and the complex of the outwardly perceptible symptoms portraying the present malady, which are organized by the dynamis in the organism, form a whole. They are one and the same. The organism is indeed a material instrument for life, but it is not conceivable without the life imparted to it by the instinctual, feeling and regulating dynamis, just as the life force is not conceivable without the organism. Consequently, the two of them constitute a unity, although in thought, we split this unity into two concepts in order to conceptualize it more easily.
