Book: The Wisdom of the Eternal Law
Harmony also implies a disharmony, as a new harmony in opposition to the former, in a way that the harmonic aspects can oppose one another and disharmony emerges from such opposition. Within substantial mutations and within all types of mutations, one can observe that the law of harmony is obeyed and, once such harmony is broken, the beings – that broke it – are integrated into a new harmony. Therefore, there are true specific leaps, qualitative leaps that occur in the passage from one harmonic state to another. Such passage is symbolized by the law of seven, which is the law of cosmic evolution.
As we have to consider each thing concretely by its unitary aspect, by intrinsic and extrinsic opposition, by the relations (series), by the interaction and form, we also have to conceive it as part of a harmony and, subsequently, by the possibilities to break the harmony and become an element of a new form.
 Evolution not in the Darwinian sense, or, as Mario puts it, “not in an axiological sense”, i.e., of a passage from a “worse” to a “better”, but as a passage from a “anteriority” to a “posteriority” (not in a temporal sense, though, but logical, ontological and mathetical).
