Book: The Wisdom of the Eternal Laws
All finite beings constitute an unity, a totality, an arithmos plethos (the arithmos of its totality). Such totality has a cohesion, the power to coact, which coherences its parts, coherences the composing elements of its dyadically opposite structures.
As totality, there is [within the being] a primary function, belonging to the whole, to which subsidiary functions of the opposites are subordinate and that analogizes it to the hipokeimenon of the being. The subsidiary functions are subordinate to the primary function, which abide by the interests of the totality. When the functioning of all parts and the respective subsidiaries subordinate to the normal given by totality, we have what the Pythagoreans called harmony. Harmony is the sixth ruling law of all finite beings and it is symbolized by the hexagram.
The law of harmony is not the result of a symmetry of opposites, but of a subordination of subsidiary functions of the opposites, analogized to a normal given by the whole according to its interest that can naturally have greater or lesser levels of intensity. The harmony observed on a cell or on a living being is greater than the harmony on an artifact, for instance.
Not only the entities unitarily considered constitute harmonic sets, but also, whilst unities, can be elements of totalities, of sets, of systems, in short: of bigger structures, to which they are subordinate. The law of harmony rules over all things and, whenever something breaks such law, the severance is merely apparent, since, once breaking the harmony of a set, the unity starts to integrate the harmony of another set. Thus, the law of harmony that rules the universe of beta context proclaims that the subsidiary functions of the composing elements, ordained within the set of oppositions, work obediently to a normal given by their belonging totality. As, naturally, there are levels of being within the finite things (things of beta context), there are, also, levels of harmony. Disharmony, therefore, does not break the law of universal harmony, but it breaks only a particular one, so the element moves to act within another harmony.
