A Natural History of Natural Theology

This monograph presents a cognitive science approach to understanding why humans persistently engage in natural theology across diverse cultural contexts. De Smedt examines how evolved cognitive mechanisms shape human tendencies to reason about divine attributes, design in nature, and theological concepts, arguing that natural theology emerges from ordinary cognitive processes rather than specialized religious faculties.

The work synthesizes research from cognitive science of religion, developmental psychology, and evolutionary psychology to explain the cross-cultural prevalence of theological reasoning. De Smedt demonstrates that children spontaneously develop intuitions about purposeful design in nature and non-human creators, suggesting these concepts arise from maturationally natural cognitive systems. The author argues that teleological thinking, agency detection, and intuitive dualism constitute cognitive foundations that make natural theological arguments intuitively compelling across cultures.

Central to De Smedt's analysis is the claim that natural theology represents a predictable output of evolved minds confronting questions about origins, order, and purpose. The work examines how hyperactive agency detection mechanisms and promiscuous teleology in human cognition predispose people to perceive design and intention in natural phenomena. These cognitive biases, while adaptive in social contexts, generate persistent intuitions about cosmic designers and ultimate purposes.

The monograph critically engages with both defenders and critics of natural theology. Against theologians who view natural theological arguments as products of careful reasoning, De Smedt suggests these arguments often rationalize pre-existing intuitions generated by cognitive mechanisms. Conversely, against critics who dismiss natural theology as mere cultural indoctrination, the author demonstrates its basis in universal cognitive tendencies that manifest even in secular contexts.

De Smedt's contribution reframes debates about natural theology by shifting focus from the validity of theological arguments to the cognitive processes generating them. This naturalistic approach explains why design arguments and cosmological reasoning recur across cultures without validating or invalidating their conclusions. The work suggests that understanding the cognitive foundations of natural theology can illuminate both its persistence and its limitations.

The monograph's interdisciplinary methodology bridges cognitive science and philosophy of religion, offering empirical grounding for discussions typically conducted through conceptual analysis alone. By treating natural theology as a cognitive phenomenon amenable to scientific investigation, De Smedt provides tools for understanding why certain theological ideas seem intuitively plausible while others require extensive cultural scaffolding. This approach promises to inform both religious and secular perspectives on humanity's persistent theological impulses.
