Natural Man

The author reviews competing accounts of human origins, foregrounding evolutionary explanations over literal creation narratives and arguing that scientific evidence supports descent from lower organisms. He traces how early humans, living in precarious conditions, developed language, fire, tools, and social organization, and explains how religious belief evolved from fetishism to anthropomorphic deities. Moral qualities and cleanliness are depicted as acquired cultural developments rather than innate traits, with civilisation presented as the outcome of collective adaptation and the gradual suppression of more brutish tendencies.
