About the Author

Mohammad Rasoul Mohseni Rajaei is an independent researcher whose professional experience and academic interests span economics, banking, systems analysis, and investment management, alongside a broad and sustained interest in the fundamental questions of human beings and societies.

In addition to his education and professional experience in economics and banking, he has pursued extensive independent studies in physics, philosophy, psychology, sociology, and history. This interdisciplinary approach has contributed to the development of a perspective in which human and social phenomena are examined not as isolated events, but as interconnected components of a larger system.

This intellectual journey led to the development of the theory of “Human Constants,” an attempt to identify relatively stable patterns underlying human behavior and the organization of societies, beyond their historical, cultural, political, and civilizational differences.

The theory focuses on four fundamental domains: survival, connection, meaning, and order. Its central proposition is that although these dimensions may manifest themselves with different forms, intensities, and contents across societies, they appear to play relatively stable fundamental roles in the continuity and organization of human life.

The book “Human Constants” represents an effort to formulate this perspective theoretically and to move from conceptualization toward measurement and application. The author's objective is not to present a final or absolute explanation of the complexity of human beings and societies, but rather to propose a research framework that can be tested and evaluated in historical, social, political, and civilizational studies.

The author's approach in this endeavor emphasizes testability, openness to criticism, and the possibility of further theoretical development, rather than presenting a closed and unchanging theory. From this perspective, the value of the theory becomes evident when, in confronting historical and social evidence, it can demonstrate both its explanatory power and its limitations.

“Human Constants” is therefore not merely the product of a study within a single discipline; it is an effort to build a bridge among the natural sciences, the humanities, and the analysis of social systems—an effort whose continuation may lead to the development of measurable indicators, comparative studies of civilizations, and empirical testing of the theory across different societies.
