This essay explores the role of religion, science, and the secular in contemporary society by showing their connection to social and political legitimacy as a result of historical processes. In Chapter One, the essay presents historical arguments, particularly linguistic, which confirm science and religion as historically created categories without timeless or essential differences. Additionally, the current institutional separation of science and religion was politically motivated by the changing power structures following the Protestant Reformation. In Chapter Two, the essay employs the concept of the modern social imaginary to show how our modern concept of the political and the secular subtly reproduce the objectified territories of science and religion and thus the boundary maintenance dialectic which dominates science-religion discourse. Chapter Three argues that ‘religious’ worldviews contain genuine metaphysical claims which do not recognizably fit into these modern social categories. Given the destabilizing forces of globalization and information technology upon the political authority of the nation-state, the way many conceptualize of these objects religion, science, and the secular will change as well.
