In The Growth of Culture and the Evolution of Mind, Clifford Geertz challenges traditional views on human evolution, arguing that culture and biological development are not separate, sequential phenomena but interdependent forces that have shaped human cognition. Traditional evolutionary perspectives held that biological evolution laid the groundwork for human intelligence, after which cultural accumulation took over as the primary driver of development. Geertz, however, proposes a more dynamic interaction: culture itself played a role in shaping the biological evolution of the human brain.
The chapter begins by dismantling the "critical point" theory, which posits that a sudden, almost magical genetic mutation led to the emergence of human culture. Instead, Geertz asserts that culture and biological evolution co-developed over an extended period, particularly during the Pleistocene epoch. The emergence of tools, social structures, language, and symbolic systems created new environmental pressures, favoring individuals who could adapt to and expand these cultural forms. This feedback loop led to significant changes in brain structure, cognition, and social behavior.
Geertz also critiques the idea that the human mind is a fixed, innate entity. He suggests that cognitive capacities are deeply embedded in cultural contexts, making it impossible to separate intelligence from the social and symbolic structures that shape it. The chapter concludes with the assertion that the human nervous system itself is configured to depend on culture for its full development. This perspective places culture not as an addition to human life but as an essential component of what it means to be human.
Review
This chapter is a crucial contribution to cultural anthropology and evolutionary theory, as it reconfigures how we understand the relationship between biology and culture. Geertz’s argument is both elegant and profound: humans did not first develop fully formed cognitive abilities and then acquire culture—rather, culture was an active force in shaping those abilities. By presenting an integrated model of cultural and biological evolution, Geertz moves beyond simplistic nature-versus-nurture debates and offers a more nuanced view of human development.
One of the chapter’s strengths is its interdisciplinary approach. Geertz synthesizes insights from anthropology, evolutionary biology, psychology, and neuroscience to create a compelling case for his argument. He effectively critiques outdated evolutionary models and demonstrates how symbolic systems—language, art, ritual—are not mere reflections of human intelligence but integral to its formation.
However, the chapter is dense and assumes a familiarity with both evolutionary theory and cultural anthropology. While Geertz’s prose is engaging, his arguments require careful reading. Some critics might argue that his emphasis on culture’s role in shaping cognition risks downplaying the importance of genetic and neurobiological factors. Nonetheless, the chapter remains a landmark text that continues to influence discussions on human evolution, cognition, and the role of culture in shaping human experience.
