After establishing her model on the basis of science’s classifications of genus, species, and individual, Edith Stein proposes axioms for just how the species is informed by the genus and the individual by the species, i. e., how one comes to know and be filled with the content of who one is. She introduces the concept of “affinity.”
“The laws would not only govern the combination and separation of elements (which could not be transformed into one another) but also limit how every element may be combined that each elementary form has a potency for certain combinations (this is called ‘affinity’).” ~Potency and Act
Affinity presupposes laws governing the order of actualization within the genus to the species and the species to the individual. Importantly, however, we note that affinity does not imply “determinism.” The freedom of the individual is at work. Affinity simply implies more or less fullness of content and order from one classification to the other. We are most actualized, most complete, most properly ordered, the more we freely develop along our God-given affinities. This is a key conclusion, a foundational statement, supporting the Monarchy and the royal heart. The Monarch must freely accept the content offered through the genus and species by which they are informed and in which they have a given affinity if they are to be truly royal.
Next Stein introduces “motion,” or act, as a necessary complement to affinity in order for this all to happen. The actualization of the individual through affinities within the genus and species implies “motion.” Elements making up wholeness come together necessarily by both their affinity for each other and motion, or act. Being free, we must will to become all we can be by pursuing the affinities within the form’s content.
“The emergence of compounds also supposes motion, but it supposes affinity as well.” ~ Potency and Act
Now we have the basis to explain the ordered effects of causality through motion and affinity. This causality is a downward flowing dependent relationship, as in genus down to species and then to individual. And it is interdependent across éléments, as in affinity, whereby one element within the classification relates to another. Stein calls each respectively, “supramundane” and “intramundane” causality.
“We have thus met a number of different causalities, both ‘supramundane’ and ‘intramundane.’ ‘Supramundane causality [Kausalitat]’ means the dependence [Bedingtheit] of created being and what occurs therein on uncreated being and ‘intramundane causality’ the interdependence within created nature.” ~ Potency and Act
Thus, royalty is both God-given through dependent classifications and interdependent affinities within those classifications, but must be freely embraced through motion, or the act of the will. Royals are both born and made.
