Louis Dumont described the predecessors of Externatus: Homo Aequalis and Homo Hierarchicus. We may say that Hierarchicus himself had two ancestors. Let us call them Polytheis, representing the dominance of multiple deities, and before him, Animis, representing an era when nature held supreme power. These five phases, Animis, Polytheis, Hierarchicus, Aequalis, and Externatus, partially overlap. One complicating factor is that their timelines vary across regions. While the West has generally set the historical pace, in a contemporary North African family, for example, grandparents might embody Hierarchicus, parents Aequalis, and their tech-savvy children already Externatus. Animis and Polytheis are anthropological figures linked to the metaculture of mythos, which expresses the Unity encompassing human beings. Hierarchicus marks the emergence of logos (based on causality), while Aequalis corresponds to the triumph of logos over mythos—whether in the form of science or the singular God, a higher principle from which human action unfolds. The era of the procedural, autonomous individual at the turn of the twenty-first century signals the rise of Externatus: based on correlations and probabilities, arithmos is their metaculture, although logos and mythos persist, despite their decline.
