by the leading classes, deterring the other as the enemy or downfall of society. By the end of the 1870s, Britain was foundering in severe depression, and throughout the 1880s class tensions, the suffragette movement, a socialist revival, swelling poverty and the dearth of housing and jobs fed deepening middle class fears. Selected quotes Development of the degeneration concept The earliest uses of the term degeneration can be found in the writings of Blumenbach and Buffon at the end of the 18th century, when these early writers on natural history considered scientific approaches to the human species. With the taxonomic mind-set of natural historians, they drew attention to the different ethnic groupings of mankind, and raised general enquiries about their relationships, with the idea that racial groupings could be explained by environmental effects on a common ancestral stock. This pre-Darwinian belief in the heritability of acquired characteristics does not accord with modern genetics. An alternative view of the multiple origins of different racial groups, called "polygenic theories", was also rejected by Charles Darwin, who favored explanations in terms of differential geographic migrations from a single, probably African, population. The theory of degeneration found its first detailed presentation in the writings of Bénédict Morel (1809–1873), especially in his (Treatise on Degeneration of the Human Species) (1857). This book was published two years before Darwin's Origin of Species. Morel was a highly regarded psychiatrist, the very successful superintendent of the Rouen asylum for almost twenty years and a fastidious recorder of the family histories of his variously disabled patients. Through the details of these family histories, Morel discerned an hereditary line of defective parents infected by pollutants and stimulants; a second generation liable to epilepsy, neurasthenia, sexual deviations and hysteria; a third generation prone to insanity; and a final generation doomed to congenital idiocy and sterility. In 1857, Morel proposed a theory of hereditary degeneracy, bringing together environmental and hereditary elements in an uncompromisingly pre-Darwinian mix. Morel's contribution was further developed by Valentin Magnan (1835–1916), who stressed the role of alcohol—particularly absinthe—in the generation of psychiatric disorders. Morel's ideas were greatly extended by the Italian medical scientist Cesare Lombroso (1835–1909) whose work was defended and translated into English by Havelock Ellis. In his L'uomo delinquente (1876), Lombroso outlined a comprehensive natural history of the socially deviant person and detailed the stigmata of the person who was born to be criminally insane. These
