"Principle of equality among Humans: two identical Humans, two equal Rights"
Aequalitas (Principle of Equality among Humans) :

Having established the Right to be of the Human destined to be, the question then arises: what are the implications of this new Right?
This part is about parallelism: from one case to another, from one Human to another:

« TODAY, I WANT TO PROTECT (moment of legal recognition)...

...HER PRESENCE TOMORROW ! (subject of legal recognition) »
=
(means)

« TODAY, I WANT TO PROTECT (moment of legal recognition)...

...HER PRESENCE TOMORROW ! (subject of legal recognition) »
Principle of equality among Humans:
Two Humans of the same nature: one shared Will, two equal Rights.
"The 'you' I Wish today to protect is not limited to the person you are today, but also extends to the person you are destined to be in the future.
Therefore, I must not consider the embryo in terms of what it is today, but rather with a view that extends toward its future.
And, I cannot deny that, in the future, the embryo is the same person as the 'you' I Wish to protect".
It has just been proven that the Human the embryo is destined to become possesses a Right to be/to exist. Such a legal datum radically alters the manner in which each individual adjudicates on the matter of the embryo. Indeed, at present, no one considers the person the embryo is destined to become (IIIA). No one has yet understood that the embryo must be considered only in light of the person it is destined to become (IIIB).
