The author’s approach

The author’s aim is not to offer a final or definitive answer to the complexities of humans and society, but to propose a research framework to be tested, as an analytical tool, in historical, social, political and civilizational studies.

Testability

The theory’s value shows when it meets historical and social evidence.

Openness to critique

A theory must also make its own limits visible.

Capacity for development

An open theory, not closed and unchangeable.

Natural sciences⟷Humanities⟷Analysis of social systems

“Human Constants” is an attempt to build a bridge among these three fields; its continuation can lead to developing measurable indicators, comparative studies of civilizations and empirical testing of the theory across different societies.

“Despite diversity, humans constantly seek continuity, meaning and order; and in that search, civilizations form and fall.”
