This works challenges both theologians and sociologists. For theologians, original sin is portrayed by Saint Augustine, around 1700 years ago. His formulation has been discredited by the science of genetics. If Adam and Eve associate to the Developed Neolithic, then they cannot be the parents of all humanity. On January 2, 2024, Razie Mah proposes, in his blog, that a second doctrine of originial sin should be proposed, with the hypothesis of the first singularity in mind. For sociologists, who have set forth the notion of the post-truth condition as a way to model post-modern society, especially after 1989, theory flounders on the rocks of explicit abstraction. Explicit abstractions cannot picture or point to the inherent relationality within implicit abstraction. Triadic relations cannot be observed and measured. Yet, humans adapt to their potentials. This work shows diagrammatic techniques that place explicit abstractions into relational structures characteristic of implicit abstraction. Diagrams of judgment and the category-based nested form abound. In short, when a theologian looks at sociological theory concerning the post-truth condition, reflecting in the mirror of theology, the image should call to mind original sin. When the scientist looks at the second doctrine of original sin, reflecting in the mirror of science, the image should call to mind the post-truth condition. Look and see. Part 3 of 3.
