Book: The Wisdom of the Eternal Laws
The relations within a being of beta context occur in such a way that the opposites are simultaneously active and passive, more or less active or passive, so that the active part of one acts upon the passive part of the other, and vice versa. There is, between them, an inter-action, of which one symbol is the Chinese Yin-Yang. Now, the Yang is not purely active, neither the Yin purely passive; Yang is predominately active-passive and Yin, predominately passive-active. Such inter-action that happens in all finite beings reveals an efficient actuation, however com-proportionate to the nature not only of what is efficient, but also of the efficaciousness of the receiver of determination. The capacity to determine of one is consequently proportionate to the capacity of being determinate of the other. One part is acted upon and the other, naturally, resists. Every determination of beta context beings presents resistance. Clay, as a matter for the brick, offers resistance, a delimiting action upon the form in which the efficient cause tries to imprint in it. Therefore, the fourth fundamental law, the law of interaction, also called law of reciprocity. The analogized opposites, in their relations, do more than inter-actuate: they reciprocate. The law of quaternary symbolizes, in many religious conceptions, the cosmic order – viewed from a material angle. All material things are ruled by those four laws: of one, of two, of three, and of four. Therefore, those four laws constitute the fundamental laws of all material cosmic order. This is one of the definitions or, better said, one of the symbolic contents of the Pythagorean Tetrad.
The law of reciprocity can be observed within all entities in their intrinsic opposition, the opposition that is formed between the analogized opposites that interact, and also in extrinsic oppositions and extrinsic interactions. So that all things can be viewed unitarily in itself, dyadically in its oppositions, ternarically in its series (in its relations and also as beginning, middle and end) and quaternally as a result of opposites reciprocity, all of which interact proportionally to its determinative and determinable capacities. The law of reciprocity rules the primary and fundamental evolution of finite beings, rules the dynamicity of finite beings. As the Pythagoreans called it, it is the “law of fundamental evolution”.
