Objectivity and Subjectivity Revisited: Towards a Shared Human Ontology

Human beings have long struggled to explain the relationship between the external world and the inner life of the self. Across philosophy, psychology, and neuroscience, objectivity and subjectivity are typically treated as mutually exclusive categories, a division that obscures their deep interdependence. This paper argues for a conceptual shift: from viewing objectivity and subjectivity as antagonists to understanding them as co-constitutive dimensions of human existence. Drawing on interdisciplinary scholarship—phenomenology, cultural psychology, neuroscience, and philosophy of science—I examine how subjective experience permeates all acts of knowing, including scientific inquiry itself. Empirical evidence from contemporary Q methodology highlights the diversity of perspectives on subjectivity, while historical analyses reveal the persistent but unacknowledged role of subjective factors in knowledge-making. I propose that action is not merely the expression of an inner subjectivity but the very actuality through which subjectivity becomes objective. Recognizing this continuum invites a cultural psychology that integrates mind, world, and history, challenging the residual dominance of mechanistic naturalism and opening new possibilities for understanding the human condition.
