The chapter explores the concept of the individual as a democratic citizen who voluntarily exercises rights and authority, and can both legitimize and delegitimize the government. It suggests that Western secular cosmological dualism, which separates the world from man, has led to the development of the modern individual, capable of introspection, autonomy, and agency. This dualism creates a divide between the physical human body and the autonomous human mind and spirit. It has facilitated the simultaneous growth of natural sciences and humanities. The chapter examines how this secular imaginary, based on the separation of Nature and man since the seventeenth and eighteenth centuries, is reflected in the philosophical discourses of influential thinkers like Hobbes, Descartes, Locke, Rousseau, Hume, and Kant. They explored the potential of this separation to evolve human agency in politics and to derive universal rights from Nature to safeguard individual freedom in society and politics. This dual cosmology also led to the development of social sciences and varying views on voluntarism and natural determinism, as seen in Freud’s psychoanalytic theory. Finally, it shows how Nature has become a cultural resource through art.
