I am not sure that I would consider “human nature” to be a system in the same sense that in biology we can consider an assemblage of organs or related tissues concerned with the same function to be a system, or the entire human or animal body considered as a functioning unit as a system. The deeper question considers what is the organizing principle of the organic system.
In non-biological reality, we recognize many systems, too, such as the solar system.
Biological systems, while very complex, are no more irreducibly complex than are physical systems or such things as plate tectonics. In fact, if we strictly apply Behe’s definition of IR systems, then plate tectonics involves irreducible complexity.
As far as I can tell, the human person is the only irreducible complex organism, system, or whatever.
Long ago, I had started work on the following proposed thesis:
"The possibility of two sole parents of the human species lies within the nature of the human person,”
Once the true nature of the spiritual soul is determined and thus true human nature specified as an intimate, unique unification of spirit/matter, rational/corporeal, soul/ body – once that endeavor is accomplished – it would be possible to defend the proposed thesis:
As a consequence of returning humanity to its proper place at the pinnacle of creation, man’s spiritual soul, including its powers of intellect and will, becomes the sufficient reason to reexamine science’s assumptions of polygenism which is based on only part of the real, true human nature
Ah, one says. Spirituality cannot be put under a natural science microscope. True. But that does not exclude spiritual reality which can be known by the tools of reason, self reflection, logical evaluation, and analytical thought. These tools are part of human nature – the human being one sees in the mirror.
It must be completely understood that science is not excluded from this thesis. Nor are the various science disciplines being trashed. Science must contribute its knowledge in the material/physical realm. Even the age and development of the earth presents vital knowledge as to the environmental conditions suitable for human beginnings.
This means that an independent review of scientific literature would be conducted from an analytic position, hopefully one which is free from restraints. Of special interest would be the methods and materials sections. Also to be considered would be questions regarding the extrapolation of particular results to universal conclusions.
The
Catechism of the Catholic Church, paragraph 355, points out that in his own nature, the human person unites the spiritual and material worlds. This is truly awesome!
