Robin Horton’s critical and creative writings on African religious thought have influenced anthropologists, philosophers, and all those interested in the comparative study of religion and thought. This selection of some of his classic papers, with a new introduction and postscript by the author, traces Horton’s theoretical ideas over thirty years. In attempting to understand African religious thought, he also tackles broader issues in the history and sociology of thought, such as secularisation and modernisation. Part I is a critical assessment of two established interpretive approaches, the Symbolist and the Theological. Part II proposes an alternative ‘Intellectualist’ approach that emphasises the structural and processual similarities between religious and scientific thinking. The postscript appraises the Intellectualist approach in the light of recent theorising about religion and world views.
