Observing the nature of a complementary pair, we will use man and woman for the example:
1. A base isomorphism is observed where key elements (the angulature of the shoulders of the man relative to the hips of a woman observe inverse properties in not just "position" (height) but also form (angle vs curve), the male genitals as a projective form and female as a receptive void, etc.)
2. While elements (head, arms, etc.) exist through a replication, this replication exists through a constant variation because of this isomorphism. So the replication of symmetry observes a constant nature but exists through the variation of "isomorphism" as an inversion.
3. The synthesis, joining, of these isomorphisms (ie through sex) results in the continual replication of these symmetries (children) as well as the replication of isomorphism (the child may be male or female, even in hermaphrodites there is always a state in which one set of genitals are active and the other is not) as subject to a "symmetry" in and of itself (replication of dualisms).
4. The isomorphism (male and female), while replicated through joining still observes a quality of repitition in and of itself. The male and female genitals, while inverse, observe a linear form where one is represented through an active state and another through a passive (receptive void) state.
5. Isomorphism is the grounding of observing 1 form through many forms beginning fundamentally with a dualistic state.
6. This dualism, as "many", observes that the repetition of a phenomenon cancels out this separation in one respect (as the male/female dichotomy exists through the replication of children) through a continual repetition of a constant form (human) as "1" chain of movements but simultaneously allows for the dualism to be maintained (replication of male and female) in which isomorphism occurs through recurssion.
7. This isomorphism and recurssion (repitition) exists as the nature of "mirroring" where symmetry is maintianed through time as the constant repetition of one symmetry through many variations. In simpler terms contradiction is grounded in multiplicity through variation, premised in isomorphism, but recurssion allows a continuation of symmetry resulting in an inherent unity of a phenomena through time.
