Herbert Spencer was one of the most important contributors to the Victorian discourse on social evolution. His theory of evolution in nature and society has been the subject of countless scholarly works over the last hundred years. Nevertheless, not all of its dimensions have been studied in due depth. Contrary to a widespread belief, Spencer did not just design an evolutionary theory of upward, yet branched development. Searching for explanations for the social distance between presumably civilized and primitive societies and (...) between presumably well-conducted and pauperized Victorians, he introduced elements of retrogression into his theory of social evolution. In addition, he biologized social structures and social phenomena by constructing a causal relationship between social and somatic features. This article discusses Spencer's account of the social conditions of the so-called savages and paupers. It aims to shed light on the progressive and retrogressive modes of evolutionary development and the biologistic explanations he employed in his social theory to explain these conditions. (shrink)
